Wavetables
A library of moving spectra, not frozen waveforms.
- 22 morphing wavetables — FM, formants, bells, super saw and more
- Two wavetable oscillators plus sub and noise
- See the waveform at the current position, and drag it to morph
- Mipmap anti-aliasing: clean highs at any pitch
Synth Engine
The full CurlySynth voice underneath.
- 16-voice polyphony, unison for wide stacks
- Filter with its own envelope, two LFOs and a mod matrix
- Poly, mono and legato modes with sustain-pedal support
Step Sequencer
Write basslines and riffs on a piano roll, not with sliders.
- Piano-roll grid from C2 to C5: tap to place notes, drag to draw
- Per-step gate, slide, accent, probability and ratchet
- Swing and four play directions: forward, backward, ping-pong, random
- 40 ready-made sequences in classic bass and lead styles, plus your own
Arpeggiator
From classic up-and-down to rhythmic patterns.
- 11 patterns, including converge, diverge, pinky and chord
- 16-step rhythm mask: rests, ratchets and accents
- Swing and three velocity modes
- On-screen keyboard to play it without a MIDI controller
XY Pad & Clock
Two parameters under one finger.
- The XY pad drives any two parameters across their full range — wavetable position included
- Bypass puts every value back where it was
- Master clock: host-locked in your DAW, tap tempo standalone
FX Rack
Seven effects on board — the patch is finished inside the synth.
- Drive (2× oversampled), chorus, delay, reverb
- Pump, compressor and 3-band EQ
- Soft-limited master — push it safely
Presets
A sound library that grows with you.
- 81 factory presets plus your own (.cswt)
- Shared browser across the CurlySynth line
- Musical randomizer for happy accidents
MIDI & Control
Hands on everything.
- Right-click MIDI Learn on every control
- MIDI channel filter and host BPM lock for synced LFOs and delays
