Nonlinear circuits VCO demo Part 1

Published on May 28, 2017 Randy Piscione

"Demo of a Nonlinearcircuits VCO. From the nlc website, 'The VCO is a standard Mikulic/Electronotes core with phase sync and pan-pulse circuitry from the Aries AR-338.' This is from 2012.

I created a custom (and not particularly attractive) panel to house two of these behind it. Going to do another video to demo the sync and FM but probably something more performance-oriented.

Nonlinear circuits VCO demo Part 2

"Here is the second part of the Nonlinearcircuits VCO demo. This one is just a performance, no talking (yes!). Just me showing off. I am at various times manually tweaking the tuning on the VCO to affect the Hard sync, and the frequency and modulation depth on the various CV inputs. It’s all live, so if you can manage to listen to all of it, there are some interesting sounds coming out of this thing. See the details below for what I’m using. This is a very cool and very capable VCO.

Here are the details:

The bass sequence and drums are from a Mutable Instruments Anushri. Everything else is the nlc VCO, just one VCO, one side, no filter. Sync (hard) is coming from the other side of the nlc VCO. Output is the PanPulse. PWM is handled by a Frequency Central Wave Runner, Sync Mod is a PM Foundations 3080 VCO, PanPWM is a TipTop Z3000, DC FM is modulated by an nlc ADSR 312, which is causing the Sync to move a bit when I play the keyboard. AC FM is modulated by an X-4046 VCO through a Fonitronik Cascade. An MFOS VCA is using CV from another nlc ADSR 312 to handle dynamics, and that is going to a Ladik M-171 Mixer."
