Wavetables for Electra 3
Tone2Software synthVerified
What a Electra 3 wavetable import expects, and how a Hyperwave export maps onto it.
What Electra 3 can (and can't) load
No user wavetable import. Custom Wave loads single-cycle .wav waveforms (files under 4,096 samples are treated as single cycles; longer files are resynthesized from the middle section) — but wavetables remain built-in only, unlike Icarus.
What Hyperwave exports
Every Hyperwave export is one packed wavetable WAV. Check these facts against the Electra 3 format above — where the two disagree, the fix is almost always the frame size or a conversion step, not the sound design.
- Sample format
- 32-bit float by default (values between -1 and +1); 16-bit WAV is a direct export option for targets that load integer banks.
- Channels
- 1 (mono). Every frame is one single-cycle waveform.
- Header sample rate
- 48,000 Hz by default. This is a label in the file header — for wavetable import it doesn't stretch or resample your frames. One exception: VCV Rack's Wavetable VCO reads the sample-rate field as the frame length when it's a power of two, and sample players that fall back to one-shot mode use it for pitch.
- Frame layout
- Frames are packed end-to-end in one data chunk, in wavetable order; the export filename records the shape as name-{samples}x{frames}.wav.
- Resolution
- The live table runs from 8 to 8,192 samples per frame and 8 to 1,024 frames (defaults 2,048 × 256).
- Metadata
- No extra metadata chunks are written — targets that read frame size from metadata have to infer it from the file itself.
Design the table once in Hyperwave's node graph and export the packed WAV — wherever it's headed next.
