Who wins on what

Ranked by what users actually praise

Overall Impression

The interface makes FM synthesis genuinely approachable. Multiple commenters highlight how the slider-based, visual-spatial layout demystifies FM programming compared to classic menu-diving synths like the DX7. Users say it's a 'must have' for learning FM, with one noting it's a big step up in usability even after decades of FM experience, calling the layout something that just 'works' for hands-on learners.

Sound design range impresses across FM and analogue-style patches. Owners praise the engine for sparkling FM chimes, weird evolving digital noise, warm tones surpassing older DX7/DS8 machines, and surprisingly convincing analogue emulations like supersaws and sub-bass via operator tricks. Several call it a 'sound designer's dream,' citing filters, alternate waveforms, and effects like the Rotary and MS20 LPF as key to its versatility and inspiring creativity.

Monotimbral operation and build quality remain persistent frustrations. Despite offering up to 64 voices of polyphony, the synth can't layer or split parts, which many call wasteful and 'redundant,' partly blamed on a Raspberry Pi compute module lacking power for multiple patches. Build and keybed quality are also called sub-par for the price, with several buyers switching to the SE keybed, VST version, or an external controller instead, and missing aftertouch on standard models.
