FM Synthesizer

for Mac/Windows ($24,99)  and iPad/iPhone ($7,99)  

FM synthesis for the masses.

Get carried away.

Baervaag is a fairly simple FM synthesizer with one carrier and one modulator. The oscillator waveforms can be modified seamlessly between sine wave to pure square wave with PWM (pulse width modulation).

  • FM Feedback, Filter, ADSR Attack and Volume can be modulated by velocity
  • Oscillators can be shaped between sine, square and PWM
  • One ADSR for each oscillator.
  • Controllable wobble factor that adds analogue unpredictability.
  • 50+ handcrafted presets created by professional musicians

  • 1. Carrier Oscillator

    This XY pad controls pulse width modulation on the X axis and the wave shape on the Y axis.

  • 2. Carrier ADSR

    Controls the carrier oscillator envelope. The attack time is optionally reactive to MIDI Velocity.

  • 3. Modulator Oscillator

    This XY pad works like the Carrier Oscillator, but it also has a frequency multiplier button.

  • 4. Modulator relative ADSR

    These sliders control the envelope of the Modulator oscillator and are relative to the Carrier ADSR. If all values of the sliders are in the middle, the Modulator envelope will be the same as the Carriers.
