Hardware MPE synths are still rare, and most are keyboards. Fred's Lab Manatee takes a different route: a compact desktop module that blends wavetable and additive synthesis, built from the start to be played with an MPE controller. Following the firmware 1.0.7 release covered by Synth Anatomy, it is a good moment to look at what the Manatee offers.
The architecture
Each voice combines two oscillators (a generator plus a sub), noise and a ring modulator, followed by a multimode resonant filter, a saturation stage, two envelopes, a custom LFO and a three-slot modulation matrix. A spectral maker, stereo delay and two stereo EQs per part round out the signal path.
The module is multitimbral with four parts and up to 16 voices in total. Although the hardware surface is small, there are more than 130 parameters inside the engine. Connections include MIDI in, thru and out, a clock input, stereo outputs, a stereo aux input and a headphone output. It is sold through retailers such as Musicstore and Perfect Circuit, and the list price reported is $999 / €749. More about the company is on the Fred's Lab website.
What firmware 1.0.7 changes for expressive players
The update, free for owners, includes several fixes aimed at MPE users: extended MPE expressors for part modulators, a fix for MPE mode initialisation from the multi page, and modwheel expressor fixes. It also adds compressors in the EQ and drive sections, a per-part master filter envelope and filter LFO, a reworked "pure" drive, improved gain staging and headroom, and a redefinable pitch pot.
None of that is glamorous, but it matters. MPE support on hardware is often judged by details like whether the synth initialises correctly when you switch modes, and whether modulation sources behave consistently across parts. Fixes in exactly those areas suggest the developer is listening to people who actually play the instrument.
How MPE is meant to work on it
The module is described as a 16-voice MPE spectral synthesizer. A comment from the developer in 2023 said the plan was for its MPE behaviour to match the company's earlier Töörö: two zones, a default single-zone mode using 15 member channels, and NRPN messages so an MPE controller can configure the synth automatically. That is a statement of intent from several years ago, not a verified specification, so check the current manual before building a rig around it.
If you want to understand the zone terminology, our introduction to what MPE is explains master and member channels in plain language.
Who it suits
Spectral synthesis rewards continuous control. When harmonic content shifts with finger pressure, a held chord stops sounding like a loop and starts sounding like a living texture. The Manatee's modulation matrix is small, but with per-note sources it can make each voice move on its own.
Players who already own a controller such as a keyboard, grid or touch surface will find the Manatee an easy way to go dawless. Four parts with 16 total voices means you can split a rig into a pad, a bass and a lead, though the voice pool is shared, so heavy chords will compete for resources.
Things to consider
The price is not small, and a 16-voice limit is real for dense MPE playing, where each finger takes a voice. Think about how you play. If you favour thick chords with slow movement, you may run into note stealing sooner than you expect. If you play melodic lines and small voicings, 16 voices is plenty.
Still, hardware MPE synths with a distinct sonic identity are welcome. The Manatee is a focused, characterful option for anyone who wants expressive spectral sound without a computer in the signal chain.
