ENV RING
This is basically an envelope follower whereby the volume of oscillator 1 is controlled by
the audio "envelope" of oscillator 2 i.e. its volume at any given time. Patch number
179:Shakin'Str uses an internal sampled percussion loop (055 Shakin'+) and shows
off the effect very well (play the lower half of the keyboard). However, here is a good
opportunity to hook up an external audio source to your V-Synth...
Start from INIT PATCH again, activate oscillator 2 and set the Type to EXT IN. Select
ENV RING in the MOD section
Feed a drum loop or drum computer into the V-Synth's inputs and play a chord. To
accentuate the rhythmic effect, use only very short percussive sounds with no reverb etc.
You can always soften the rhythmic effect by adjusting ENV RING's own Attack and
Release parameters
ENV RING is very good in combination with dynamic filtering e.g. Auto Wah (available as
Multi Effect), but we are going to "jump the gun" here and use a similar (but polyphonic!)
COSM effect. Select COSM1 and change the Type to DYN-TVF. Touch the Cutoff tab
and take Cutoff frequency (Freq) down to around 50
(input Dynamics) up until it sounds interesting
the volume of the sound source or the Cutoff frequency again. Try going to the Resonance
page and take the Reso and/or DynEnv parameter up for a much more squelchy sound.
OSC SYNC
This algorithm resets the phase of oscillator
1 every time oscillator 2 repeats its cycle,
and can have a similar effect to sweeping a
filter with high resonance and overdrive if
oscillator 1 pitch is modulated. Start again
from scratch i.e. the INIT patch in
program number 512, activate oscillator 2
and set both oscillators to SQR. Go to the
MOD section and select OSC SYNC
Experiment with the OSC1 PITCH knob,
then set it to the center again. Go back to
OSC1 and touch the Pitch pad
Sustain down to zero using the slider and
change Decay to 40

to +50 . Tune everything down an
octave 6 in the Common / Tune page
(Course = -12) and play single notes on
your keyboard as dynamically as possible –
you might recognize this type of sound
from countless Techno tracks!
