300 voice polyphony, unlimited sound layering and lots of advanced FM synthesis capabilities.
All in a compact and robust metal enclosure, useable as a rack or table-top module.
The EssenceFM is an FM synthesizer currently in development, whose pre orders will start on december 2019.
We aim to design a very powerful FM synthesis device, while making FM fun and easy to work with.
Altough power and ease of use are often hard to conciliate, we think we made this possible with an optimized user interface using a large 7" touch screen and physical buttons.
Everything in the EssenceFM is represented as graphically as possible to make it easier to see what happens as you edit a sound.
Quick'n'easy algorithm design
Graphical envelopes with preview
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, waveforms, scales, import/export from USB...

The following sounds are directly recorded from the EssenceFM prototype without any post-processing. Some recordings may have background noise coming from the recording equipment.
These sounds are not definitive. Final sound banks will consist of several hundred patches created by different sound designers to allow for a variety of styles. The EssenceFM can store approximately 3300 sounds in its internal memory.
Very wide, sitar-like pad
Layered marimba and sawtooth, with stereo delay
Guitar/rhodes-like patch with distorsion
Rythmic harp pattern with the arpeggiator, which is polyphonic
(up to 300 instances, same as the base polyphony)
Using the arpeggiator to make rythms
Rich flute ensemble sound
FM strings made of a single 6-op voice
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...)
Create layers and splits with advanced options like round robin,
exclusion groups and arpeggiator.
Design exotic scales, early temperaments and microtunings.
Use the modulation matrix to shape the sound in every possible way.
Assign parts to different audio outputs and configure each effect DSP.
