Trouble Shooting
VCO1 or VCO2 seem to be transposed to a higher or lower range.
If you un-patch a CV from one of the analogue VCOs pitch CV inputs, they will remember
the last voltage they received, and this will offset the Tune control. This will be over-ridden when
a new CV is patch to the analogue VCO pitch CVs.
VCO3 seems to play the wrong note when patch to the MIDI-CV converter.
The Tune control of the VCO3 adds to the note coming in on VCO3's pitch CV input. It acts
as a transpose control. When controlling VCO3's pitch from a CV, you must turn the Transpose
control to minimum.
The EGs are acting strange.
They both have a repeat function. To oppurate them, the sustain must be at a very low setting, and there must be a gate signal triggering the envelope. The EG will repeat as long as the
gate is present. The repeat time and output waveform can be changed with the Attack and Decay
time. If very short settings are made, an audio waveform will be present. To eliminate the repeat
function, increase the Sustain level until there is no more repeat.
I cannot get the Sequencer to clock in order.
For the sequencer to run in order from 1 to 8, if must receive a square wave. Ensure the LFO
triangle/square Level control is pulled out to select square wave. Also the Level must be turned
up suffiiciently high enough.
