MIDIbox NG Change Log

Last Release: 2016-02-08

Current firmware, schematics, additional infos are located at http://www.uCApps.de/midibox_ng.html.



  • V1.035
    • Support for secure keyboard handling if patch is switched: keep original MIDI port, note, channel when playing Note Off (this feature is not supported for LPC17 due to high memory consumption)
    • Fixed encoder incrementer in absolute mode

  • V1.034
    • Support for interpolation tables:
      MAPs can now apply linear interpolation between data points.
      This allows to quickly define curves without the need to enter the values for the complete range. E.g. previously it was required to enter 128 values to create a curve for a CC controller, now it's mostly sufficient to define the same with 3..4 data points. MBNG will interpolate the values between these points.
      Interpolation tables can be defined with following commands: MAP<n>/BYTEI and MAP<n>/HWORDI
      A BYTEI map can define up to 64 datapoints with 8bit resultion, and a HWORDI map can define up to 32 datapoints with 16bit resolution.
      Usage examples can be found under cfg/test/map* and cfg/test/kb_2.ngc
      See the user manual for further explanations.
    • Support for 16bit maps: with MAP<n>/HWORD 16bit values can be mapped.
    • label "std_rgbled" renamed to "std_rgb" to avoid error message
    • Cursor handling on SysEx based GLCD output should now work correctly if the big font is activated

  • V1.033
    • with this release, .NGR scripts running on a STM32F4 are directly executed from RAM in a compressed format, and therefore they are significantly faster, so that they could even be used for timing critical operations.
    • added basic support for SPI_MIDI
      This feature requires an update to MIOS32 bootloader v1.018
      In the bootloader update app, enter "set spi_midi 1" to enable the SPI MIDI device at J16 (RC2 chip select line). This will also disable the OSC ports via MBHP_ETH module, which is normally connected to this port.
    • support for WS2812 LED strips (currently only for the MBHP_CORE_STM32F4 module).
      The data input has to be connected to J4B.SC, ground to J4B.VS and +5V to an external PSU (required, since each RGB LED can consume up to 20 mA!)
      Following meta event commands are available:
      • RgbLedClearAll (clears all LEDs)
      • RgbLedSetRgb:<led>:<r>:<g>:<b> (led=1..64, r/g/b=0..255)
      • RgbLedSetHsv:<led>:<h>:<s>:<v> (led=1..64, h=0..359, s=0..100, v=0..100)
      • RgbLedRainbow:<speed>:<brightness> (speed=1..255, brightness=0..100)
      Most simple way to test a LED strip: enter following command in MIOS Terminal
      ngr exec_meta RgbLedRainbow:9:100
      (don't forget to wear sunglasses, or start with brightness 20!!! ;-)
    • added EVENT_RGBLED
      See cfg/test/rgbled_1.ngc for usage examples
    • .NGR file: added "set_hsv" command which allows to control the hue parameters of a RGBLED
    • SRIO num_sr= reconfiguration works correctly with DIN/DOUT matrices now
    • added "inverted=1" to EVENT_BUTTON and EVENT_LED
    • .NGR file: added "load " command which allows to switch to another setup (.NGC, .NGS, .NGR, ... files)
    • implemented new meta command "SendEvent" which allows to remote control one or more events from a single event within a given value range and direction.
      See cfg/test/metalrn.ngc for a usage example
    • implemented new meta command "LearnEvent" which allows to learn SendEvent based controller assignments during runtime. See cfg/test/metalrn.ngc for a usage example
    • added new meta command "SaveDelayedSnapshot:"
      It will request to store a snapshot after at least the given seconds.
    • added new event type "NoteOnOff", which will send a NoteOff event immediately after NoteOn (resp. actually it will send Note On with velocity 0 for runtime event optimisation)
    • added possibility to calibrate the delay_slowest values for each individual key of a keyboard.
      New terminal commands:
      • set kb <1|2> key_calibration on: delay values will be measured (method described at the MIDIbox KB webpage)
      • set kb <1|2> key_calibration off: captured delay values will be used: ( * delay_slowest / 1000)
      • set kb <1|2> key_calibration clean: shows the captured measurement values
      • set kb <1|2> key_calibration_value : allows to modify a calibration value directly
      • kb <1|2> delays: shows the measured delay values
    • keyboard calibration values are stored in a new file: .NGK, and can also be edited there
    • bugfix for DELAY_MS
    • bugfix for fwd_id to a non-existing ID with specific value
    • bugfix for maps with duplicated values
    • bugfix for sporadic file access errors reported during snapshot restore

  • V1.032
    • support for mathematical operations in .NGR script. They have to be surrounded with square-brackets ([...])
      Syntax: [<left-operand><operator><right-operand>]
      Example:
      • set LED:2000 [LED:2000 + 1]
        will increment the value stored in LED:2000
      • set LED:2000 [LED:2000 - 1] will decrement the value stored in LED:2000
      Note that nested operations are supported as well, such as:
      • send CC USB1 1 [LED:2000 + [LED:2001 + [LED:2002 + LED:2003]]]
      More examples in cfg/tests/runscr5.ngc
      Support operators: + - * / % & | ^
    • number of scanned SRIOs now configurable in .NGC file with 'SRIO num_sr=<1..32>'
      By default 32 DIN and DOUT shift registers are scanned, which result into an update rate of ca. 420 uS on a STM32F4 based core.
      With (for example) 'sr_num=8' only up to 8 DIN and 8 DOUT SRs will be scanned anymore, but the update rate is reduced to ca. 110..120 uS (a little bit more than a quarter due to SR handling overhead)
    • corrected DebounceCtr parameter (value was not passed to MIOS32).
      Now also part of the SRIO configuration, use: SRIO debounce_cycles=<1..255>
    • added new meta event "KbBreakIsMake:<keyboard-number>" which will already trigger a note event when the break contact is activated (nice for playing organ style).
      Trigger it from a toggle button function as shown in cfg/test/kb_5.ngc Can be optionally set from the terminal as well with following command: "set kb <keyboard-number> break_is_make <on|off>" (e.g. "set kb 1 break_is_make on")
    • added ain_mode=Toggle for AIN and AINSER events.
      Similar to ain_mode=Switch it can be used if buttons are connected to analog inputs. The event will toggle between the min and max value.
    • .NGR: added "set_no_dump" command. It allows to change the "no_dump" flag which specifies if an EVENT_xxx should be sent during a DumpSnapshot.
      This feature can be used to handle different snapshot setups.
    • STM32F4: support for bootloader "enforce_usb_device" flag

  • V1.031
    • the STM32F4 variant of the firmware supports USB Host mode!
      See also this forum article.
    • MIDI clock input ports now disabled by default to avoid feedback loops in various setups
    • improved "ain_filter_delay_ms" implementation to support sensors (experimental stage)
    • Covered new use case which allows to transform velocity values of incoming notes. See cfg/test/conev_6.ngc
      EVENT_RECEIVER and EVENT_SENDER have to be specified with "key=any", so that any key will be received and sent.
    • support for DIN/DOUT emulation on digital IO ports J10A/J10B (LPC17: J10/J28)
      See examples in cfg/test/diocfg_1.ngc and cfg/test/diocfg_2.ngc

  • V1.030
    • increased event pool size to 64k for MBHP_CORE_STM32F4
    • added ain_mode=Switch for AIN and AINSER events.
      Can be used if buttons are connected to analog inputs. The event will send the min value if a 30% threshold is reached, and the max value if a 70% threshold is reached.
      Schematic: Ground |----o Button o-----> analog input + 10k Pull-Up resistor to 3.3V (AIN) resp. 5V (AINSER)
    • .ngr: added "change" command. It works similar to the "set" command, but only changes the value, and doesn't generate a MIDI event.
    • .ngr: added "set_min" and "set_max" command which allows to modify the min/max range of a EVENT
    • added new meta events to control the internal MIDI clock generator: MClkPlay, MClkStop, MClkPlayStop, MClkPause, MClkDecTempo, MClkIncTempo, MClkSetTempo.
      Example can be found under cfg/test/midiclk.ngc
    • added new string formatting items:
      • %t to display MIDI clock state (Play/Stop)
      • %T to display tempo (BPM)
    • added new MClk menu page to SCS to control the tempo w/o dedicated controllers
    • fixed AOUT_NG module communication issue if AINSER was used in addition
    • added new meta events:
      • CvPitchBend14Bit:
      • CvPitchBend7Bit:
      • CvPitchRange:
      • CvTransposeOctave:
      • CvTransposeSemitones:
      see cfg/test/cvtransp.ngc for usage examples
    • BUTTON toggle function can now also handle with inverted and reduced value ranges

  • V1.029
    • added USB MIDI workaround for Windows
    • if a EVENT_SENDER is part of a radio group, and got a new value, it will only send the MIDI event if the new value is matching with the specified range.
      Usage example: cfg/templates/pg300.ngc
    • if EVENT_RECEIVER forwarded to EVENT_AIN, EVENT_AINSER or EVENT_BUTTON, send also MIDI event.
      Usage example: cfg/templates/pg300.ngc
    • support for MBHP_CORE_STM32F4 module

  • V1.028
    • DOUT_MATRIX n=8 properly supported
    • now up to 16 DOUT_MATRIX and DIN_MATRIX can be configured

  • V1.027
    • .NGR: added "set_active" command. It can be alternatively used instead of the bank mechanism to activate/deactivate events, e.g. if the same events should be activated in multiple banks under certain conditions.
      A demo can be found under cfg/tests/multibnk.*
    • it's now possible to set a static forward value independent from the actual value of the event which initiates the forwarding.
      E.g. with
           EVENT_xxx fwd_id=SENDER:1:42
      
      the SENDER:1 will always get value 42 for additional processing
    • support for multiple MBHP_MF_NG modules in a chain.
      See cfg/test/mf_multi.ngc for a configuration example
    • support for Logic Control Meters.
      Configuration example: see cfg/templates/logictrl.ngc (search for "meter")
    • added new GLCD fonts (provided by Pcbatterij): Inverted and Tiny.
      In order to test these fonts, try following commands in the MIOS Terminal:
           lcd %C&t@(1:1:1)Tiny Font
           lcd %C&i@(1:1:1)Inverted Font
      
    • fixed OSC receiver (avoided stack overflow)
    • various minor bugfixes

  • V1.026
    • support for nrpn_format=MsbOnly (e.g. for MBSEQ V4 NRPNs)
    • new EVENT parameter ain_sensor_mode:
      • With ain_sensor_mode=NoteOnOff, AIN and AINSER events, which are assigned to Note events, send velocity 0 before a new Note is sent with velocity > 0 to avoid hanging notes.
      • With ain_sensor_mode=None (default if no sensor mode specified), Note events will be generated as a continuous stream like CCs

  • V1.025
    • new terminal commands:
      • ngc: allows to execute a .NGC command directly
      • ngr: allows to execute a .NGR command directly
      • ngr_section: sets the ^section for .NGR execution
      • ngr_value: sets the ^value for .NGR execution
      • run: can now also executed without specified <section> <value>
        (the previously set values will be taken in this case)
    • inofficial support for MAX72xx chains - see cfg/tests/max72xx.ngc for a configuration example (no schematic available yet)
    • .NGR: fixed "delay statements in if branches" issue
    • .NGR: added "set_lock" command. It allows to prevent, that received events will overwrite a value of an event.
    • .NGR: the "set" command now also allows to change variables, e.g.:
      set ^value 1
      set ^section 2
      set ^bank 3
      (etc...)
      the last one (^bank) will also switch MBNG to the specified bank
    • .NGR: added variables ^dev, ^pat, ^bnk, ^ins, ^chn
      These are the same which can be used in SysEx strings, and which can be changed in a SCS page (e.g. the variables could also be used for different purposes)
    • added new SCS menu page to execute the .NGR file with given ^section and ^value
    • the AIN command now supports the "resolution" parameter
    • the AINSER command now supports the "muxed" parameter.
      Use muxed=1 for the AINSER64 module (default), and muxed=0 for the AINSER8 module.
    • AIN and AINSER events, which are assigned to Note events, send velocity 0 before a new Note is sent with velocity > 0 to avoid hanging notes.
    • added "ain_filter_delay_ms" to support sensors (experimental stage)
    • EVENT_RECEIVER in conjunction with ^txt or ^txt56: if ^cursor is not specified in the SysEx stream, it will start at offset 0 from the specified lcd_pos=::
    • EVENT ... syxdumppos now supports the full receiver range 1..4095 (previously only 1..15)
    • the MIDI router forwards SysEx messages regardless if channels are filtered, or "All" is used. It's ensured that messages are only sent once if multiple router nodes forward to the same destination port.

  • V1.024
    • bugfix for "single_usb" option
    • support for LED Digits (7-segment displays).
      Configuration examples can be found under cfg/tests/leddig*.ngc
    • the DIN_MATRIX and DOUT_MATRIX configuration command now allows to mirror the row pattern with "mirrored_row=1"
    • added EVENT_RECEIVER emu_enc_mode and emu_enc_hw_id parameters.
      See cfg/tests/emu_enc.ngc for an usage example
    • .NGR now allows to cast the ID type: (id) or (hw_id).
      E.g. (id)LED:1 will search for the EVENT specified with id=1, and (hw_id)LED:1 will search for the EVENT specified with hw_id=1
      if (hw_id) is used (default if no type specified), and no EVENT with a matching hw_id can be found, a virtual event will access the control element directly. This is currently only relevant for the SET command.
      This matches with the behaviour of the "EVENT ... fwd_id=" function.
    • added RunStop meta event to stop the execution of a .NGR file
    • added "runstop" terminal command
    • new .NGR command: set_rgb
      E.g. "set_rgb (id)LED:1001 15:8:4"

  • V1.023
    • the current AIN/AINSER pot values can now be taken over by the meta events RetrieveAinValues and RetrieveAinserValues
    • new .NGR command: EXEC_META

  • V1.022
    • support for run scripts.
      See also the new manual page.
    • the new SysEx command ^label has been added. It allows to insert the ASCII code of a label string into a SysEx stream.
      See also cfg/tests/syxlabel.ngc
    • big GLCD font now correctly handled by ^txt and ^txt56 SysEx command
    • line number now displayed on errors in .NGC, .NGL or .NGR file
    • various bugfixes and improvements

  • V1.021
    • support for the "single_usb" option, which can be enabled with the bootloader update application V1.012 ("set usb_single 1")
      Use this option if you are working with a Windows PC which can't handle the 4 USB ports correctly (e.g. stucking MIDI, Filebrowser operations are failing, etc.)
    • added .NGS file which allows to store and restore values into up to 128 snapshots (0..127).
      The snapshot can be changed in the "Snap" menu in the SCS
    • the "Snap" menu also allows to dump all events (e.g. after a new snapshot has been loaded)
    • added new (hopefully selfexplaining) meta events:
      SetSnapshot, DecSnapshot, IncSnapshot, CycleSnapshot, LoadSnapshot, SaveSnapshot and DumpSnapshot
      Note that multiple meta commands can be assigned to an event, e.g. to set, auto-load and dump a snapshot from an encoder write:
      EVENT_ENC ... type=Meta meta=SetSnapshot meta=LoadSnapshot meta=DumpSnapshot
    • added "no_dump" parameter to EVENT_xxx
      It specifies if an EVENT_xxx should be sent during a DumpSnapshot.
      no_dump=1 is set for EVENT_RECEIVER and EVENT_KB and events which are using type=Meta by default.
      If such events should be part of the dump, set no_dump=0 For all other events/types no_dump=0 is set by default, set no_dump=1 if they shouldn't send MIDI events on a snapshot dump.
    • new label printf-control "%S" prints the snapshot number 0..127

  • V1.020
    • added "rgb" parameter.
      See cfg/tests/rgb_*.ngc for various examples.
    • added "spread_center" option to AIN/AINSER calibration.
      See cfg/tests/kb_1.ngc for an usage example.
    • reduced memory consumption of EVENT_* definitions
    • added MIOS Terminal commands: "show id" and "show hw_id"

  • V1.019
    • added "Autoload" function: whenever a .NGC file has been uploaded via the MIOS Filebrowser, it will be automatically loaded, so that "load <file>" doesn't need to be entered in the MIOS Terminal anymore.
    • EVENT_LED_MATRIX: now expects the 'colour' parameter to address the red (colour=0), green (colour=1) or blue (colour=2) LED.
      Note that it's still possible to control the LEDs from a single incoming MIDI message, e.g. by assigning the 3 EVENT_LED_MATRIX entries to the same CC number. But now it's also possible to address the LEDs independent from each other.
    • LEDs can now be dimmed with 16 brightness levels over the value range.
      This feature has to be enabled with dimmed=1 in the EVENT_* definition.
      Configuration example: cfg/tests/dimled.ngc
    • LEDs in a matrix configuration can be dimmed as well. The dim range is the same (0..15), but the effective dim level is limited by the number of scanned rows:
      • 4 rows: only 8 levels (0..1, 2..3, 4..5, 6..7, 8..9, 10..11, 12..13, 14..15)
      • 8 rows: only 4 levels (0..3, 4..7, 8..11, 12..15)
      • 16 rows: only 2 levels (0..7, 8..15)
      Configuration example: cfg/tests/dimled_m.ngc
    • the new MIOS Terminal command "lcd" allows to directly output a (formatted) string to the LCD(s).
      E.g. try "lcd @(1:1:1)Hello World!"
      Note that terminal strings can also be sent via SysEx from a DAW:
      F0 00 00 7E 32 00 0D 00 <ascii-text> 0A F7 Accordingly, this SysEx string will print "Hello World!" as well:
      F0 00 00 7E 32 00 0D 00 6C 63 64 20 40 28 31 3A 31 3A 31 29 48 65 6C 6C 6F 20 57 6F 72 6C 64 21 0A F7

  • V1.018
    • added EVENT_KB. See cfg/tests/kb_*.ngc for usage examples
    • new LCD formats: %N prints the note name based on the specified MIDI event, and %n based on the event value
    • new meta event: SwapValues - it swaps the primary and secondary value of an event.
      E.g. on a note event, velocity can be swapped with the key value.
      A usage example can be found in cfg/tests/kb_4.ngc, where the key and velocity value should be output by separate CV channels
    • AIN/AINSER configuration: added pinrange parameter.
      It allows to specify individual ranges for the connected pots to calibrate the physical min/max limits.
    • SCS configuration: added SCS num_items and lcd_pos parameters

  • V1.017
    • it's now possible to use the same hw_id in multiple event definitions. This allows for example to send multiple MIDI events from a single control element (e.g. from a single button)
    • the fwd_id now forwards to the event(s) with the given hw_id (which is the same like the "normal id" if not explicitely specified)
    • implemented "conditional events".
      See the User Manual for details and examples.
    • the new meta event UpdateLcd allows to force a refresh of the complete LCD content. This is especially useful in conjunction with conditional events: whenever a source value has been changed (e.g. a button state), all events which have this value in their condition will print out the label if the specified condition matches.

  • V1.016
    • LPC17: robustness of LCD driver has been improved

  • V1.015
    • support for GLCD_SSD1306_ROTATED
    • the ^txt and ^txt56 SysEx command now allows to map incoming characters to different cursor positions. An example can be found in cfg/templates/logictrl.ngc
    • independent from this map feature, ^txt and ^txt56 now also take lcd_pos=... and label=... into account to set the initial LCD and cursor position, at which the message will start. The label can be used to change the GLCD font before the characters will be print.
      An example can be found in cfg/templates/logictrl.ngc as well.

  • V1.014
    • the keyboard handler of MIDIbox KB has been integrated. The configuration commands are identical "set kb..." as documented at the MIDIbox KB page.
    • keyboard parameters are also stored in the .NGC file, and can be configured from there.
    • please note that the latency is 10 times higher than in the MIDIbox KB application! Each row is scanned in 320 uS (instead of 32 uS).
      This has to be considered in the velocity delay configuration. delay_slowest should be 100 (instead of 1000), and delay_fastest should be 5 (instead of 50)
    • DOGM and SSD1306 GLCDs: support for more than 12 displays via DOUT shift registers connected to J28

  • V1.013
    • overworked LCD handling: there is no buffer limitation anymore, any LCD and GLCD size is accepted, which especially means that GLCD fonts are displayed correctly independent from the specified number of connected devices.
    • this change has freed some RAM which can be used for other purposes in future

  • V1.012
    • The application boots a little bit faster now
    • support for more than 2 LCDs.
      A documentation can be found in the User Manual.

  • V1.011
    • EVENT_SENDER and EVENT_RECEIVER can now also be assigned to a radio_group.
      This can not only be used in conjunction with BUTTON/LED radio groups, but also to distribute MIDI events to from receiver to multiple senders without forwarding chains (which then can be used for a different purpose)
    • the "sdcard_format" command allows to format the connected SD Card with FAT32 from the MIOS Terminal

  • V1.010
    • SysEx: added ^cursor, ^txt and ^txt56 identifiers.
      They allow to send messages to the LCD via SysEx.
      A usage example can be found under cfg/templates/logictrl.ngc
    • Labels: ^# allows to terminate a label.
      E.g. "^label^#MyText" prints "MyText" directly after the specified ^label

  • V1.009
    • with a button assigned to 'type=Meta meta=MidiLearn range=0:1' it's now possible to activate a MIDI Learn mode which allows to assign an incoming MIDI event to any control element
    • with 'type=Meta meta=MidiLearn range=0:2' also NRPN events can be learned (in this case, CC#62 and CC#63 will be ignored!)
    • MIDI Learn mode can also be activated in the SCS menu

  • V1.008
    • DIN_MATRIX with rows=4 now properly supported
    • DIN_MATRIX/DOUT_MATRIX: it's now possible to invert the rows as well:
      inverted=1 or inverted_sel=1 will invert the selection lines
      inverted_row=1 will invert the row pattern
    • configuration examples for the 16x4 Button/Duo-LED matrix are now available under cfg/tests/blm16x4*.ngc

  • V1.007
      o changed bank concept: the BANK command has been removed, instead the EVENT command got a new "hw_id" and "bank" parameter.
      A simple configuration example can be found under cfg/tests/encbanks.ngc
      More complex configuration examples under cfg/tests/bnk*.ngc
    • added meta=CycleBank (increments bank, resets to 1 if last bank reached)
    • additional new metas: SetBankOfHwId, DecBankOfHwId, IncBankOfHwId, CycleBankOfHwId

  • V1.006
    • corrected LED pattern output for the case that the selection lines are inverted.
    • the new SCS command allows to assign emulated button/encoder functions if the SCS shows the mainpage.
      A usage example can be found under cfg/templates/lre8x2.ngc

  • V1.005
    • support for value MAPs.
      Various examples can be found under cfg/tests/map*.ngc
    • support for EVENT_CV
      Various examples can be found under cfg/tests/cv*.ngc
    • AINSER modules now disabled after RESET_HW
      They have to be explicitely enabled with the AINSER command
    • the AINSER command now supports the "resolution" and "num_pins" parameters

  • V1.004
    • some minor code cleanup

  • V1.003
    • added "enc_speed_mode" parameter to EVENT_ENC
      Valid modes are:
      • Auto (speed automatically adapted according to the value range),
      • Slow:0 .. Slow:7 (divides the increments),
      • Normal (no special measure) and
      • Fast:0 .. Fast:7 (accelerates the increments)
      A configuration example can be found under cfg/tests/encspeed.ngc

  • V1.002
    • the patterns specified with LED_MATRIX_PATTERN are now reversed so that the bit orientation matches with the hardware.
    • reversed value ranges (min value greater than max value) now properly supported
    • support for ain_mode Direct/Snap/Relative/Parallax
    • incoming MIDI values can now trigger the output of EVENT labels if the "fwd_to_lcd" option is set to 1 in the related EVENT_* definitions.
    • support for "Radio Groups": button and LEDs can now be assigned to groups, which handle the same value over multiple elements.
      A configuration example can be found under: cfg/tests/radiogrp.ngc

  • V1.001
    • maximum length of DIN/DOUT shift register chain increased to 32.
