Shoom is a brand new iOS polysynth which offers three independent synth engines and X-Y control over a wide variety of scales, from 12-tone equal temperament to microtonal and everything in between.

Operating within a 20–20,000Hz pitch range, the app can effectively achieve every note and harmonic audible to the human ear along its control surface. However, should you not want to get all xenharmonic, then you can snap to a scale grid of your choosing.

The app supports MIDI CC control and clock sync, but MIDI note input is not yet available. It should arrive in an update very soon. The synth comes with 60+ presets to get you started.

Shoom offers Inter-App Audio and Audiobus 2 support and is available now on the Apple App Store for the introductory price of £4.49/$5.99.

Synth engine features include:

  • Adjustable polyphony, up to 30 voices
  • Two oscillators with 4 waveforms and PWM, and one noise generator
  • Oscillator FM cross-modulation
  • 4 pole (24 dB/octave) resonant low pass filter with overdrive and pitch tracking
  • 2 variable slope ADSR envelopes for amplitude and filter cutoff
  • 2 LFOs with 9 waveforms, up to 3 out of 12 simultaneously assignable parameters, trigger and global running modes, fade-in and phase controls
  • Y axis position as modulation source with up to 3 of 15 simultaneously assignable parameters
  • Note pan randomizer
  • Built-in stereo delay and reverb effects
