Helm is a free, cross-platform polyphonic software synthesizer with extensive modulation capabilities, available as a standalone application and as LV2/VST/VST3/AU/AAX plugins. It offers 32-voice polyphony, dual oscillators with unison, LFOs, a step sequencer, arpeggiator, and built-in effects.

Use cases

  • create electronic music with a free software synthesizer
  • add a polyphonic synth plugin to my DAW
  • synthesize sounds with deep modulation and LFOs
  • make music on Linux with an open-source VST synth
  • use a free alternative to paid software synthesizers
  • experiment with waveshaping, filters, and effects for sound design

When to choose

  • you want a free, GPL-licensed synthesizer with no DRM
  • you need a synth that runs standalone or as a plugin on Linux, Mac, or Windows
  • you want rich modulation options with visual feedback
  • you need polyphonic synthesis with built-in effects like reverb and delay

When to avoid

  • you need a actively developed project with recent updates and support
  • you require sample-based or wavetable synthesis rather than subtractive synthesis
  • you need commercial support or guaranteed bug fixes
