/*CHANGE LOG

0.6.16:
add gate status feedback in steps (white lights)

0.6.15:
add right-click menu option to bound AutoStep writes by sequence lengths

0.6.14: 
rotate offsets are now persistent and stored in the sequencer
allow ctrl-right-click of notes to copy note/gate-type over to next step (not just move to next step)

0.6.13:
fix run mode bug (history not reset when hard reset)
fix slide bug when reset happens during a slide and run stays on
add live mute on Gate1 and Gate2 buttons in song mode
fix initRun() timing bug when turn off-and-then-on running button (it was resetting ppqnCount)
allow pulsesPerStep setting of 1 and all even values from 2 to 24, and allow all gate types that work in these
add two extra modes for Seq CV input (right-click menu): note-voltage-levels and trigger-increment
fix tied bug that prevented correct tied propagation when editing beyond sequence length less than 16
implement held tied notes option
clear all attributes (gates, gatep, tied, slide) when cross-paste to seq ALL (CVs not affected)
implement right-click initialization on main knob

0.6.12:
input refresh optimization
add buttons for note vs advanced-gate selection (remove timeout method)
transposition amount stays persistent and is saved (reset to 0 on module init or paste ALL)

0.6.11:
step optimization of lights refresh
change behavior of extra CV inputs (Gate1, Gate2, Tied, Slide), such that they act when triggered and not when write 
implement copy-paste in song mode
implement cross paste trick for init and randomize seq/song
remove length and arrow buttons and make steps with LED buttons
add AutoSeq option when writing via CV inputs 

0.6.10:
add advanced gate mode
unlock gates when tied (turn off when press tied, but allow to be turned back on)
allow main knob to also change length when length editing is active

0.6.9:
add FW2, FW3 and FW4 run modes for sequences (but not for song)
right click on notes now does same as left click but with autostep

0.6.8:
show length in display when editing length

0.6.7:
allow full edit capabilities in Seq and song mode
no reset on run by default, with switch added in context menu
reset does not revert seq or song number to 1
gate 2 is off by default
fix emitted monitoring gates to depend on gate states instead of always triggering

0.6.6:
knob bug fixes when loading patch

0.6.5:
paste 4, 8 doesn't loop over to overwrite first steps
small adjustements to gates and CVs used in monitoring write operations
add GATE1, GATE2, TIED, SLIDE CV inputs 
add MODE CV input (affects only selected sequence and in Seq mode)
add expansion panel option

0.6.4:
turn off keyboard and oct lights when detached in song mode (makes no sense, can't mod steps and shows stepping though seq that may not be playing)
removed mode CV input, added paste 4/8/ALL option (ALL copies length and run mode also)
allow each sequence to have its own length and run mode
merged functionalities of transpose and rotate into one knob
implemented tied notes state bit for each step, and added light to tied steps
implemented 0-T slide as opposed to 0-2s slide, where T is clock period
changed copy-paste indication, now uses display rather than keyboard lights

0.6.3: 
added tie step macro button
added gate probabilities (one prob setting for all steps)
removed paste-sync

0.6.2:
initial release of PS16
