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 , go to OSC1 and change the waveform to SAW.

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 , Freq KF to +100 and Dyn

(input Dynamics) up until it sounds interesting . Note that you might also have to adjust

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 . Flip

Sustain down to zero using the slider and

change Decay to 40 . Change the

Velocity Curve to 1 and Env Depth

to +50 . Tune everything down an

octave 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!
