Sustain pot of ENV2 to its maximum. Turn the three Mixer pots, and the four small pots in the filter
section to their minimums. Listen to the main output. It should be silent. Now turn up the VCO1 to
VCA pot, and you should hear a triangle wave at the same pitch as VCO1. Turn the Sustain pot of
ENV2 down and the volume of the triangle wave should also go down.
Turn the Sustain pot back up and the VCO1 to VCA pot down. Turn the filter mode switch to Shape
and the Shape control to LP (Low Pass). Now turn up the level control of VCO1 on the mixer and
select sawtooth. The signal you hear now will be the one going through the filter. Check that the
Frequency and Resonance controls do their usual thing. Turn the Shape control and listen to sound
change. It should become a fizzy high pass sound at the HP end and a phaser like sound in the
middle. Flip the mode switch into BP and the filter will be in band pass mode. This should
accentuate only one narrow band of frequencies and create sounds reminiscent of a wah-wah pedal
when the ASV's resonance is turned up.
Turn the VCF FM2 control up and you should hear the LFO modulating the filter's centre
frequency. The LFO's waveform is a sine wave. Turn VCF FM2 down and now turn up VCF FM1.
This allows VCO2 to modulate the filter and it'll probably just produce burbling out of tune noises
at the moment. Turning up the filter's resonance control will accentuate the burbling.
Now insert the gate connection to the Gate input again. Check that the ASV's output is now
controlled by your keyboard. Make sure that the envelope controls of ENV2 are behaving correctly.
Turn the ENV1 Depth control to its maximum and now check that ENV1 is behaving correctly. If
you have access to velocity CV from your midi-CV convertor or keyboard then connect this to the
ENV1 Accent socket. Check that playing harder on your keyboard sweeps the filter more strongly
when the ENV1 Depth control is not at its central position.
If all is well then it is time to calibrate your ASV. Please see the User Manual for details on the
calibration process.
