/* DUY Code: ARP Arpeggio example */

/*
 * Example script of RK002 arpeggiator.

 * PARAMETERS (accessible via DUY Portal or SysEx without compiling)
 * MIDICHN    : working input MIDI channel  (1..16)
 * MODE       : 0=off, 1=UP, 2=DOWN, 3=ALTERNATE, 4=RANDOM, 5=AS_PLAYED
 * OCTAVE_MIN : range min 0-4
 * OCTAVE_MAX : range max 0-4
 * CLOCKLENGTH: ARP clock length 1-48
 * GATE       : gate length: 1=1/4, 2=2/4, 3=3/4, 4=1, 5=5/4 etc.
 * TRANSPOSE  : ARP transpose 0-36
