PLAN B analog blog

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:

Sample 2:  PWM demonstration

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

Sample 3:  

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

Sample 4:  Minimode 2 with internal sync.  Same patch as above with
the external sync function turned on:

Sample 5:  Sloped Random Waveform demo

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:

Sample 6:  Sine purity demo


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

Sample 7:  VC waveshape demo

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:

Sample 8:  Frequency Shifting demo


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:
