Helm

Matt Tytel

Helm is a polyphonic software synthesizer developed by Matt Tytel, offering comprehensive sound design capabilities through oscillators, filters, modulation sources, and effects. It combines classic subtractive synthesis architecture with advanced features like cross modulation, feedback comb filtering, formant synthesis, and a step sequencer, making it suitable for everything from warm pad creation to aggressive bass design and experimental timbral manipulation.

Written from the manual and checked against it. How we check

Key Features

01Filter with 12dB and 24dB low/band/high pass filters plus low/band/high shelf modes, blendable responses, and key tracking
02Feedback comb filter with semitone transpose and cent tune for harmonic manipulation
03Stutter module with independent stutter and resample frequency controls plus fade softness
04Formant filter with XY pad for vowel sound morphing (ee/ah/eh/oh corners)
05Four distortion types (soft clip, hard clip, linear fold, sine fold) with drive and mix controls
06Three modulation sources: ADSR envelopes (amplitude, filter, modulation), LFO with waveform and frequency controls, step sequencer with up to variable steps and slide smoothing

Things to Try

  • 01Set unison to 5 voices with 10 cents detune and enable harmonize mode to create a harmonically rich, orchestral tone
  • 02Use the formant filter by clicking different spots in the XY pad to smoothly morph between vowel sounds (ee at top-left, ah at bottom-left, eh at top-right, oh at bottom-right)
  • 03Enable stutter with softness at 100% to create smooth, windowed repeats with sine-wave fading between steps
  • 04Map an LFO to the filter cutoff with a saw-up waveform and adjust tempo sync to create evolving filter sweeps locked to your session tempo
