A wavetable builder for synths and hardware

Draw, import, and morph single-cycle waves into 1D and 2D wavetables, listen as you edit, and export in the format your synth or module expects.

From the makers of SampleStack.

From a single cycle to a finished table

Draw and shape
Pencil, line, curve, and harmonic tools. The curve tool bends a wave, squeezes it into an envelope, or limits it between two curves, with templates and an optional region.
Build whole tables
Start from one frame and sweep brightness, filter, fold, sync, formant, PWM, and more across a 1D table or a 2D grid. Keyframes fill in the frames between them.
Import what you have
Serum and Surge tables open directly. Plain WAVs can be sliced into fixed-size frames, or single cycles can be pulled out of a pitched recording.
Export for your gear
Serum-style WAV, plain WAV, or Surge .wt, at any frame size and bit depth. Device profiles for the Disting NT and EX, Deluge, Serum, Vital, and Surge XT check and convert tables on the way out.
