waverider digital vco

price : $350.00



waverider digital vco here we go! now in production, wavetable vco with tons of features: cv'd interpolating waveforms, cv'd subosc waveforms and octaves, cv'd glide, bitcrushing and more!

frequency the frequency cv input accepts 0-5v control voltages, quantized to semitones, to cover the midi note range 0-63. it is possible to limit the cv input with the cv attenuator. the basic frequency range of the vcdo is ten octaves from midi note 0 to midi note 120 (8.18hz to 8372hz), and can be selected by the manual frequency knob.

detune the detune cv input is not quantised, and allows for -5v to +5v cv to modulate +/-8 semitones. the manual detune knob allows adjustments to be made +/-100 cents.

waveform the vcdo section has 16 waveforms which you're unlikely to have seen before, arranged as a wavetable. the vcdo is able to crossfade from one to the next, creating a wavetable which you can scan through under voltage control, -5v to +5v. it would have been easy to include standard waveforms like ramps and triangles, but there are many oscillators that produce those. this oscillator has its own character and provides something different.

sub wave as well as the main oscillator, there is also a sub oscillator with 8 waveforms. each waveform can be selected at one of four octaves, either +1 octave (above the main osc pitch!), in unison, -1 octave, or -2 octaves. additionally, the sub wave can be selected externally by cv, -5v to +5v.

glide waverider also includes a glide/portamento effect, glide times range from 12ms/octave to 2.4secs/octave. turning the glide knob to minimum switches the glide effect off. additionally, glide can be externally controlled by any gate source, 0v = glide off, 5v = glide on.

crush the crush knob controls the sample bit resolution of the output (ie bitcrushing). this can be reduced from 8-bit down to 1-bit in eight steps.

vcdo and sub osc outputs 8-bit, 62.5khz sample output rate. the internal waveforms and calculations are 8-bit, and new samples are output via the on-chip pwm modules at 62.5khz. the pwm modules' outputs are at 125khz.

audio samples:
first up, 2 x waveriders, using my kenton pro 4 to use them both as a duo-synth. so this is 2 x waveriders into 2 x system x vca's, controlled by 2 x loopenv generators

some douphonic kometenmelodie

this next soundclip uses an lfo to cycle through the sub-oscillator's octaved waveforms. just to make it clear, there is no arpeggiator or sequencer being used all live action

next up, using both lfo and adsr to modulate the main wavetable

next clips featuring just the suboscillators their waveforms are more conventional than the main vcdo output, and lend themselves to some subtractive synthesis.
so here's 2 x waverider sub oscillators through my system x filter

...and here's 2 x waverider subs through a multimode in hpf mode

this one feature 2 x waverider subs through different vcfs, with an lfo modulating the waveform/octave of one waverider to create a pseudo-sequence no sequencers or arpeggiators were used.

waverider is 14hp and 55mm deep
