INSTRUCTIONS FOR MIDI INTERFACE 
SEQUENTIAL CIRCUITS PROPHET 5 

USING THE MIDI INTERFACE 

When you turn on the synthesizer for the first time, you will be in omni-on mode for 
receive (all channels) and channel 1 for transmit - See next page for factory default 
settings. When you select a transmit or receive channel, this will be stored in memory 
and will be remembered for when you subsequently turn on the synth - all parameters 
listed on the next page are stored. 

If you want to put the machine back to the factory default settings at any time, switch 
the synth on whilst holding the red push button pressed - hold for a couple of seconds 
then release. 

RED PUSH BUTTON 

Three modes are available by pushing the red push button. Before you press the red button 
however, make sure that no notes are pressed on the synth otherwise the results may be 
unpredictable. 

1) PATCH CHANGE MODE 

Pressing once only enters patch change mode. Any key then selects a patch change which it 
sends through MIDI. YOU are then automatically returned to playing mode. 

2) SET-UP MODE 

Setting MIDI channels and assignments. Give the red push button two short presses (half 
a second each) - then release. Follow ttiis with a note or sequence of notes as detailed 
on page 2. After selecting a channel you will be .automatically returned to playing mode 
but after making assignments you will need to press the ENTER key (Top C) to return to 
playing mode. This is to enable you to make the multiple key presses required when 
reassigning sources to destinations. (N.B. setups are stored in non-volatile memory). 

3) TRANSPOSE MODE 

Press and hold the red push button for four seconds - then release. Middle C will sound 
on the synth and continue to sound until you press a key. The note that you press will 
be the new middle C for MIDI IN. You can set any value up to two octaves up or down. 
Settings outside this range will be ignored. Note that transpose mode cannot be entered 
from program mode. 

ASSIGNING MIDI CONTROL SOURCES TO DESTINATIONS 

SOURCES                   DESTINATIONS                   (d)=factory default 

AFTERTOUCH                off / modulation (d)/ p.bend / vcf / resonance 
CONTROLLER X              off / vcf (d) / not used
CONTROLLER Y              off / vcf / resonance (d) 
VELOCITY                  off (d) I vcf / vca 
MIDI VOLUME               off / vca (d) 

Sources can control more than one destination at once, but a destination can only be 
controlled by one source at a time. Thus if velocity is currently controlling VCF and 
then you switch aftertouch to VCF, velocity will then control nothing until reassigned.
