More PLL

 Last week the Doepfer A196 was integral to synthesizing a flute. Since that worked out well I wanted to dive deeper into the functions of this module. While recreating the Buchla 259 Complex Waveform Generator still eludes me, another cool voice came out of the A196 today. Behold a screeching cello!

Phantasie for Cello Patch by jeremiahfisher

This voice was pretty easy to create. Here is the barebones idea:

Osc 1 square wave into A196 input 2. A196 square wave out into filter. Filter output into VCA. VCA output into wavefolder. Wavefolder out to mixer/soundcard/etc.

The modules I used with the A196 were an Analogue Systems RS95e, Tiptop Audio Z2040, and a Toppobrillo Triple Wavefolder. The z2040 has a built in VCA. I used a Malekko Envelator to open the VCA. The Doepfer A149 Source of Uncertainty controls rise/fall time of the envelope and pitch of the RS95e.

Mess with knobs and switches until satisfied with the result. You could also add portamento with a slew limiter and vibrato with another vca.

The accompaniment in Phantasie for Cello Patch is two drones: one from my e350 and another from a bunch of oscillators through a matrix mixer.
