A wavetable is a row of waveforms, each a single cycle. The Wavetable plays one of them in a loop, at the requested pitch. Between two neighboring frames, it crossfades: as you turn Position, the sound glides from one shape to the next, with no clicks. The screen shows the 8 frames of the bank, stacked, and in color the wave being played right now.
Controls
- Tune, Fine: the pitch, like the VCO (octaves, semitones).
- Position: from 0 (first frame) to 1 (last).
- Bank: five banks of 8 frames, computed by the synth.
- Classic: sine, triangle, saw, square, then narrower and narrower pulses.
- Harmonics: like the drawbars of an organ, each frame adds harmonics.
- Voice: vowels, from "oo" to "ee" through "o", "ah", "eh", "ay". The tone talks.
- Metal: a sine folded harder and harder, bright and metallic.
- Lo-fi: staircase waves, the grit of old samplers.
- FM: depth of the FM input (at full, +1 V = one octave).
- Pos CV: depth of the Pos input. At 1, 10 V sweep the whole bank; negative, the CV moves the position backwards.
Inputs
- V/Oct: the pitch. FM: exponential pitch modulation.
- Pos: CV added to Position. An LFO, an envelope, or even an audio signal for a grinding tone.
Outputs
- Out: the wave, at ±5 V. The tables are band-limited per octave: practically no aliasing, even up high.
