MIDI Control Codes
 1  TEMPO ADJ / DATA control. The default 
application for this control is to allow adjustment of 
the MIDI clock speed set by the VCF 2 TAP 
TEMPO button  3  . With the control in its mid 
position the clock speed is unaffected. Rotate anti-
clockwise to reduce, or clockwise to increase the 
clock speed. This allows external sequencers or 
drum machines to be accurately aligned to the BPM 
of pre recorded tracks. 
An internal jumper can be reassigned to change the 
function of this control to a dedicated DATA send, 
and will output Control Change CC94. See Service 
Options for details. 
 2  START / STOP button. Sends MIDI start/stop 
data to an external sequencer or MIDI device. The 
Lights yellow when pressed. Push once to transmit 
MIDI start data, push again to transmit MIDI clock 
stop+rewind data. MIDI output: 
 ON (1
st
 press), STOP/REWIND (2
nd
 press). 
3  TAP TEMPO button. The tempo of the MIDI 
clock is set by tapping it in using the button. The 
BPM is determined by the last two button presses.

independently output MIDI data 0 to 127: 
 VCF 1 FREQ: Control Change CC12 
 VCF 2 FREQ: Control Change CC13

MIDI data 0 (farthest left) to 127 (farthest right).
