MIDIbox SEQ Change Log
Last Release: V2.4c @ 2006-07-24
- V2.4a/b/c
- if not in songmode, the Fwd and Rew button can now be used to
increment/decrement the menu value. This is a nice alternative
possibility for "fine adjusting" values without the datawheel
- the clock rate of the external clock pin is now selectable from
96 ppqn to 24/13 ppqn in the BPM menu - just press one of the 16
general purpose buttons. With 96 ppqn the clock output is
permanently 1 (thats not a bug)
24 ppqn is the standard setting (GP button #4)
- a new option has been added which allows synchronized pattern
switching, the pattern will be changed with the next measure
(after the 16 steps of the "master track" have been processed)
- a new option has been added for arpeggiator mode which avoids
that the track position will be reset if no note/chord is played
- there is a new "MBSEQ Options" menu page which allows to select
these two new features online
- V2.4
- the arpeggiator has been enhanced by "Multi-Arp" events
The details are described in the 4th tutorial session
- a 24ppqn clock output is now supported to synchronize with vintage drum machines and sequencers.
The signal is available at pin #15 (RC0, CORE::J6::RC)
- V2.3
- the clock can now be divided by BPM/1,2,3,..15,16 for each track
separately. Before this change it was BPM/1,2,4,8,16,32,64.
It's possible to switch back to the old behaviour with the
DEFAULT_BPM_DIVIDER_BEHAVIOUR switch in main.asm
- the song menu handling has been overworked:
- for 2*2x40 LCD option, there is now an additional info screen
at the right side (second display)
- song mode can be enabled/disabled in song menu by pressing
the SONG button (again)
- if not in song mode, the pattern set will be changed
immediately (see usecases below for the reason)
- song position now named A1..P8 instead of 1..128 for easier
orientation
- song positions are now divided into parts A..P, each part
consists of 8 pattern sets, each pattern set can be looped
up to 16 times.
- song number, song position, loop/jumps now controllable with
the general purpose buttons
- Usecases of the new song handling:
- a) for song mode enter the song menu and press the button twice.
Press the "A" button + one of the 16 GP buttons to select the song
Press the "B" button + one of the 16 GP buttons to select the part
-> the sequencer will change to the part immediately, if the
sequencer was not running before, it will be started automatically
- b) this allows you to divide a song into multiple parts. At the
end of a part, you can either set a jump to the first step
of the part (so that the part loops), or you can set a jump
to the next part.
Note: if a song part consists of 8 song positions, it is not possible
to set an additional jump. The sequencer will jump to the next
part automatically (this ensures compatibility)
- c) it's always possible to change the part during the sequencer
is running - it won't affect the realtime behaviour :)
This allows you to change between breaks/fills/chorus or
whatever during a live session
- If you don't want to use the song mode, the new handling is
still useful for you - it allows to save up to 128 pattern
sets within a song.
Press the "A" button + one of the 16 GP buttons to select the song
Press the "B" button + one of the 16 GP buttons to select the part
(this already provides a quick access to 16 pattern sets)
Turn the datawheel to select pos 1..8 within a part
Similar to song mode, changes will take place immediately
without affecting the sequencer timings. The selected pattern
set will loop endless until you are changing to a new one
- V2.2
- a drum mode has been implemented which allows to play three drum lines
per track (makes up to 48 drum lines which can be played in parallel)
In this mode, each layer contains one drum line.
Limitations: each line has a dedicated note and gatelength. Only
two velocity values can be specified (normal and accent)
The accents can be set when the FAST button is activated.
More details are described in Tutorial #3
- single events can now be triggered multiple times (up to 4 times per step)
with a delay value of 1-31. The number of triggers and the delay can
be selected in the gatelength layer.
This feature allows to play doubled, triplet and quadrupled notes,
which is especially useful for drumrolls, ratterbeats and flams.
More details are described in Tutorial #3
Note: the new definition of the gatelength makes old patterns
incompatible to previous releases (better to do it now than
never) - the gatelength has to be divided by 4 in old patterns
- a humanizer function has been added which allows to add/subtract
random values from the 2nd MIDI byte (e.g. Note), from the 3rd
MIDI byte (e.g. Velocity, CC value, Aftertouch...) and from
the gatelength.
The humanizer mode and intensity can be selected in the Groove menu
- two additional gate trigger pins are now available for the AOUT option.
The 3rd gate is located at pin RC0 (CORE::J6::RC)
The 4th gate is located at pin RC1 (CORE::J6::SC)
These pins are only used when no AIN multiplexers are connected
(which is normaly the case when no pots are used)
- V2.1
- Two morphing modes have been integrated into the application:
- "Smooth morphing": Layer A, B and C (on Notes: Note number,
velocity, gatelength - on CC: CC number, value and gatelength)
are faded smoothly from one to another pattern.
The morph position between these two scenes can be controlled
from the Morph menu, or with the modulation wheel of an external
keyboard
- "Threshold morphing" - especially for Note events (Drum patterns):
Note and Velocity (Layer A and B) are switched to an alternative
track once the morph position (controlled from the menu or with
a modulation wheel) passes the so called threshold level of the
played step.
The threshold can be set for each step separately in Layer C
(normaly used for the gatelength).
In other words: the threshold levels of every step are used to determine
at which morphing level the sequencer should play the note from
another track
The gatelength itself is fixed in this mode.
- Transpose/Arpeggiator hold key function improved
- Transpose works also with CC events now
- Arpeggiator view now always correctly displayed independent from the
track direction
- Fast button now also speeds up the datawheel
- gate signals of CV out now handled correctly on overlapping notes
- IMPORTANT: from now on, the SCLK input of the AOUT module has to
be connected to port J10:MD (PIC Pin #28/RD5) of the core module
The use of MIOS V1.7 is highly recommended, you will notice brighter LEDs
