is Fred's Lab most powerful machine, a 4-part 10 to 16-voice spectral synthesizer module, with full support of MPE (MIDI Polyphonic Expression).

This instrument offers original & innovative synthesis options thanks to the spectral engine, a smart blend between additive and wavetable synthesis, granting the adventurous musician the possibility to sculpt and articulate his sound from the tone spectral level.

Manatee also includes more traditionnal - Virtual Analog, Waveform and 2-Operator FM - algorithms to either complement the spectral oscillator or to be used solo.

Each voice holds 2x oscillators, an advanced noise & ring modulator, a multimode resonant filter (12, 24 dB / Octave) with extra RC section, a wild saturator module, 2x meta-envelopes + 1x custom-LFO and a classic modulation matrix. In addition to the hardwired routing, each modulation source can target many parameters and the intensity of the modulation be controlled by any available expressor (MIDI CC, Aftertouch...).

Each part carries the spectral maker, 2x custom-LFOs, a versatile stereo delay and finally 2x adjustable stereo equalisers.

A master quality reverberation module with several models (hall, plate, room ...) is also included as an insert mixing effect.


Manatee is a professional MPE & multitimbral digital synthesizer with a polyphony ranging from 10 to 16 voices (depending on patches complexity), 4 parts and multiple carefully crafted audio algorithms for sound generation.

The instrument MIDI implementation is extensive and well documented and fully complies with the recent MPE - MIDI Polyphonic Expression - specifications. Thus making Manatee the perfect companion for any expressive MIDI controller and all advanced hardware or software MIDI sequencers.

Fred's Lab instruments are still proudly & manually assembled at our facilities in Bonn / Germany using premium components and material sourced from all over the globe.
