EssenceFM

The most powerful and easy to use FM synth!


EssenceFM front panel view

  • Hybrid FM and subtractive synthesis with resonant filter
  • 300 voice polyphony (6-op FM) with layering ability to create sounds made of 12, 18, 24 or more FM operators
  • Free algorithm & envelope design: use the touch screen to link the operators together and shape your envelopes
  • 24 fully customizable waveforms, built-in effects, multitimbral, microtuning support and much more...

Ambient / Electronic

Classic FM bass, percussions, leads and lots of other sounds are inside the preset banks.

Analog

Warm analog-like sounds made with the resonant filter. Operators are used like the oscillators of a subtractive/additive synth, using FM only to build the basic oscillator sound.

Ethereal Pads

Wide atmospheric pads made by stacking layers and using the integrated reverb effect.

Orchestral

Orchestral rendition using the GM-compatible patch bank (excerpt from A.Dvorak - Symphony n°7 in D minor)

Dark ambient & SFX

Heavy use of looped envelopes and complex pitch envelopes. The Voice Sequencer helps here to create rhythmic and evolving sounds.



Designed and hand-made in France in our workshop.




Can be used as a rack or table top synth, 45° tilted support bars are provided for comfortable use.

The EssenceFM is a modern FM synthesizer representing our new vision of FM synthesis.

By using a large touch screen and dedicated knobs/keys for common operations, creating complex FM sounds is easier than on any other synth. The 1000-step undo/redo history encourages you to experiment with sound without having to worry about making mistakes!




Choose between linear and exponential envelopes


Link the operators together by drag'n'drop

Design complex envelopes easily



The EssenceFM is organized into 4 modes accessible with the buttons.

  • Performance is ideal for orchestrations, polyphonic expression controllers (MPE) or very fat sounds.
  • Patch is where you layer Voices, split them across the keyboard, detune them and setup other behaviors like the arpeggiator
  • Voice is a 6-op FM sound with its envelopes, frequency parameters, filter settings and more.
  • Global provides everything else: display and MIDI settings, waveform editing, scales...

Features

Design your own algorithms by creating links between operators.

Draw waveforms with the touch screen or import them from wave files.
The EssenceFM has 24 fully customizeable waveforms.

Make complex envelopes easily by moving the points and defining their attributes (sustain, loop start, loop end...)

Screenshot of the graphical enveloppe for volume
Create layers and splits with advanced options like round robin,
exclusion groups and arpeggiator.
