"The following are quick sound samples of the Plan B Model 30 Triple Digital VCO Subsystem.
There are no sound sources outside of a single Model 30 which is being either frequency, timbre or level controlled by external envelope generators, random voltages and LFOs. There were no filters, delays or any other types of sound processing devices incorporated.
These samples are dry.
Sample 1: Sawtooth output demo
Patch: Mini Mode 1. Three sawtooth waves:

Patch Mini mode 1. THree VCOs tuned to unison with a single envelope generator controlling PWM on each:

Patch: Mini Mode 2. Three sine waves with the amplitude of VCO 3 being controlled by a single envelope generator:

the external sync function turned on:

Patch: Mini Mode 1. Three VCOs tuned to unison, their frequency controlled by a single S+H and the output set to the second of two noise-based waveforms:

Patch: Mini Mode 1. Same pach as above with the waveforms set to sine:

Patch: Mini Mode 1. Same patch as above, this time with an external envelop generator modulating the wav eshape of all three VCOs form sine to saw:

Patch: Frequency Shift 2. A single drone controlled by five independent LFOs. One is altering the waveform of each oscillator, three other LFO set to very low amplitude are sweeping the frequency of the oscillators with one other LFO varying the amplitude of VCO2:
