Our take on the Portable FM Synthesizer, 27-Key Keyboard with 6-Operator Engine, 128 Presets, USB and Bluetooth MIDI, 16-Step Sequencer and Built-In Speaker

The CPOMS FM-1 is a pocket-sized FM synthesizer with a 27-key silicone keyboard, a 6-operator engine with 32 algorithms, and 128 factory presets. It adds six effects, a seven-mode arpeggiator and a 16-step sequencer, plus USB, Bluetooth MIDI and 3.5 mm MIDI for hooking up to software and gear. A 2000mAh battery rated around 12 hours and a built-in speaker make it a grab-and-go sketchpad. Against rivals like the Korg Volca FM or Sonicware Liven XFM, it trades a smaller, softer keyboard and fewer hands-on knobs for portability and wireless MIDI.

About the Portable FM Synthesizer, 27-Key Keyboard with 6-Operator Engine, 128 Presets, USB and Bluetooth MIDI, 16-Step Sequencer and Built-In Speaker

The FM-1 is a compact portable synthesizer with a 6-operator FM engine. It offers 32 selectable algorithms and adjustable sound parameters. 128 factory presets cover piano, string, brass, bass and synthesizer tones, and compatible FM SysEx sound library imports add more sounds.

Six built-in effects shape the sound: filter, reverb, delay, distortion, chorus and phaser. A seven-mode arpeggiator and a 16-step sequencer help build patterns. The 27-key silicone keyboard plays monophonic or polyphonic, with up to 12 voices.

It connects by USB, Bluetooth MIDI and 3.5 mm MIDI to compatible music devices and software. Sound plays through the built-in speaker, or through headphones on the separate 3.5 mm headphone jack. A 2000mAh battery gives approximately 12 hours of use, depending on volume and operating settings.

Questions and answers

Is the CPOMS FM-1 good for beginners?
Yes, if you lean on the 128 presets and arpeggiator first. The 6-operator engine is deep, so expect a learning curve before you program your own sounds.
Can it work as a MIDI controller for my DAW?
Yes. It sends MIDI over USB and Bluetooth, and has a 3.5 mm MIDI connection for compatible gear. It has no traditional 5-pin DIN MIDI port.
How long does the battery last?
The 2000mAh battery is rated for about 12 hours, depending on volume and settings. Heavier speaker use and Bluetooth will shorten that.
Does it have a real audio output?
There is a 3.5 mm headphone jack, which doubles as the line out for speakers or an interface. There is no separate 1/4-inch output.
How many voices can it play at once?
It runs monophonic or polyphonic with up to 12 voices. The 27 keys are silicone and not velocity-sensitive.
Can I load my own sounds?
Yes, it imports compatible FM SysEx sound libraries, so you can add patches beyond the 128 factory presets.
