The .mid is a shadow of the score: one channel per voice, each carrying its own pitch-bend stream. Tabota's curves and tunings are unconstrained — these settings decide only what the shadow can carry.
sthow far one channel's bend may reach before hard-walling. Must match the receiving instrument's own bend range — Kontakt generally ignores the RPN this writes.
voice 1 takes this channel, voice 2 the next, wrapping at 16.
leave the GM percussion channel out of the rotation.
writes format 1 with a conductor track. Off = format 0: one track, all channels — Reaper splits that by channel, most hosts don't.
/beatcontour sampling rate; in free time a beat is one second. Repeated 14-bit values are dropped, so a slow drift costs almost nothing.
