Primal Audio has released version 1.1 of FM4, a 4-operator synthesizer app for iOS.

Primal Audio FM4

Modelled on the popular DX series from the 1980s FM4 provides the same gritty sound, with a modern interface, and without being bound by the limitations of the original units.

Every aspect of the hardware — from envelope curves to sine-table sizes and quantisation errors to digital-to-analogue converters — has been meticulously analysed, in order to recreate the raw and dirty sound of the original units.

Changes in FM4 v1.1

  • Audiobus support.
  • iOS 7.0.x crash has been fixed.
  • Performance boost: the UI responsiveness has been drastically improved.
  • App-size has been reduced with more than 60%.
  • The manual is up.
  • Added a tempo popover with manual control of the tempo.
  • Added a waveform popover with an overview of waveforms.
  • Minor bug fixes.

FM4 is available for purchase for $9.99 USD.

A free FM4 Lite version is now also available.

The lite version is fully functional except for the following limitations:

  • MIDI is disabled.
  • Inter-app Audio is disabled.
  • Audiobus is disabled.
  • Saving is disabled.
  • Only 40 factory presets are included.
