Free new FM Synth, OctaSine, For Linux, Mac and Windows

 

Joakim Frostegård has introduced OctaSine, a free and open source FM VST2 synthesizer plugin that the developer say “draws inspiration from the Elektron Monomachine, as well as from NI’s FM8”.

 

Features:

 

  • Works on macOS, Windows and Linux
  • Four operators with independent parameters such as volume, panning, modulation index, feedback, three different frequency modifiers (ratio, free and fine) and ADSR volume envelope parameters. The operators can be independently switched to white noise mode
  • Flexible routing allowing setting the output operator (with some limitations) as well as the percentage of signal that is simply added to the final output, enabling additive synthesis. By default, operator 4 is routed to operator 3, operator 3 to operator 2 and operator 2 to operator 1.
  • Modulation panning (!), not present in FM8
  • Master volume and master frequency parameters
  • Four LFOs capable of targeting most operator parameters as well as most parameters of lower index LFOs.
  • 128 voices
  • Fully automatable
  • Preset handling
  • SIMD-accelerated audio synthesis with runtime feature detection for less CPU usage

 

 

OctaSine is available now as a free download. The source code is also available.
