2.5. ARPEGGIO CLOCK RATE
This parameter adjusts arpeggiator tempo. Parameter values are 0 to 127. Value of 0 switches
instrument’s internal clock generator on. (Arpeggio speed is adjusted by the TRIGGER - RATE slider
on the instrument’s panel or by external clock impulses form the EXT CLOCK IN connector on the rear
panel.)
Parameter values from 1 to 127 synchronize arpeggiator speed according to incoming “MIDI
Clock“ data. Higher value of the parameter corresponds to higher arpeggiator speed: Value 1
represents 127 MIDI ticks between clock pulses, value 2 represents 126 MIDI ticks, etc. The highest
value of 127 represents one MIDI tick between clock pulses. For conversion rates see table 2 – the
table contents only selected values of the parameter for frequently used arpeggiator tempos.
The value can be adjusted in two ways:
a) by MIDI controller (Control Changes) Nr. 19 - see chapter 3.1.2.
b) by SysEx Message – see chapter 3.3.

3. MIDI IMPLEMENTATION
Interface has only MIDI input - therefore it only receives MIDI commands. Interface recognizes
channel commands, common system commands and System Exclusive messages.
3.1. CHANNEL COMMANDS
Interface receives MIDI commands on selected MIDI channel (parameter "MIDI Channel"). In
OMNI mode, interface receives data on all 16 MIDI channels simultaneously.
3.1.1. NOTE ON/OFF
Interface receives Note On/Off commands on selected MIDI channel. “Key Shift“ parameter
defines assignment of MIDI notes to instrument’s keys. When four valid MIDI notes are received (all
