/*CHANGE LOG

0.6.10:
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)
update VCF code to match new Fundamental code (existing patches may sound different)
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
dark by default when create new instance of module

0.6.5:
initial release of SMS
