Simple and Powerful Audio Devices for All Musicians



The EssenceFM is a powerful hardware FM synthesizer designed to bring FM synthesis to today's standards.
It follows a very straightforward, graphical approach to make sound creation easy and enjoyable.

Release / Pre-Orders : December 2019

We believe the future of FM synthesis should not be focused on emulation but towards new systems using modern technology.
That's why we designed our custom engine called "VFM" (Variable Frequency Modulation), providing great sound capabilities while running efficiently on embedded systems.

The EssenceFM is currently in development. It will be ready for production by the end of 2019.

Huge DSP capabilities

  • 300 voice polyphony, 16 part multitimbral
  • Up to 128 stacked 6-op voices per patch
  • 24 editable waveforms with real-time interpolation
  • 2 multi effects processors
  • Powerful modulation matrix
  • Integrated arpeggiator with wave-morphing capabilities

Easy to use

  • Optimized workflow using the touchscreen, physical keys and knobs
  • Useable as a rack or table-top module
  • Free algorithm design by drag&droppping the operators
  • Graphical envelopes with real-time status display
  • Direct waveform drawing on touchscreen
  • Dedicated physical Undo-Redo keys with 1000 step history

Advanced features

  • Microtuning support
  • Waveform import from wave files via USB
  • Four balanced stereo outputs (8x 6.35mm jack)
  • MIDI-RTP (Ethernet), MPE support
  • MIDI-host capabilities
  • Upgradable firmware

It's Fast

  • 60 frames/sec screen refresh rate. No slowdowns.
  • Boot time approx. 3 seconds
  • 2ms latency

Voices are basic 6-op FM sounds, patches are instruments stacking multiple voices, while performances can be used for complete orchestrations or very (very) fat sounds.
