On this demo I wanted to give a flavour of the various tones and response curves available from the WMD / SSF Amplitude VCA, whilst under control from an envelope provided by the ADSRVCA. The WMD / SSF Blender was also used in this patch. All audio recorded direct with no processing.
Patch Details
1. A chaotic rhythmic pattern was patched together, and used to clock the Turing Machine.
2. A PDO mk.2 was sequenced by the Turing Machine, and also synced by a droning Rubicon Pulse, whose pitch was subtly modulated by a second Maths LFO.
3. Four waves from the PDO were mixed together in the Blender, with a slow Maths LFO used to crossfade between the two 2-channel Blend mixers.
4. The output of the Blender was fed into the Amplitude VCA
5. The ADSRVCA was triggered - via its Gate input - by the same erratic rhythmic pattern that was clocking the Turning Machine. It was then sent to Amplitude's VCA CV input, and also into two CV inputs on the WMD Triple Bipolar VCA (set to Phase Modulate the PDO's channels)
6. At 02.44 the ADSRVCA's envelope length was changed from LO to HI, making it much shorter and spikier.
7. During the recording various other controls were tweaked: ADSRVCA's envelope settings; Amplitude's Gain/ Saturation, CV Level, Offset and CV Response
8. For the last few seconds the Loop was switched on, so that any held (Gated) notes would produce a fast, cycling AD envelope.
All in all I'd say that I didn't hear any bleed from the Amplitude VCA, and it is capable of a very wide range of tones/ shapes - from spiky and clean, to hefty and saturated. The ADSRVCA makes a great companion for it, with some additional features demonstrated in the second demo.
