HEEL makes tuned kicks and falling bass hits for producers who need the low end to fit an arrangement. Start with a short sub anchor, a compact club knock, or a long 808 descent. Strike it, edit the part that needs work, and export the finished hit for a Drum Rack or sampler.
The pitch fall and weight contour have separate editors. Their points concentrate near the attack, where a small change can turn a soft thump into a hard knock. Harmonic weights give the body more upper presence; pressure saturates it, while attack bite adds a short pitched transient. Root frequency and length stay directly accessible.
The character stays deliberately narrow: phase-reset, mono-solid synthetic weight. You own its tuning, fall, sustain, harmonic balance and attack. There is no sample hunting or upload step.
Strike auditions the same PCM samples that go into the mono 48 kHz, 16-bit WAV. Edits apply to the next strike. Save a recipe on the device or capture its JSON to keep another version alongside the exported sound.
