On the Audioside
- Highspeed VCO using a sequencer as grafic oscillator
- Non harmonic parallel tuning (harder than soft sync but not hard sync)
- When used without fq multiplication it creates some interesting sliding
effects on the PLLed Audio-Out

Regarding the usage of control signals I did not think about it yet.
