TAETRO vs. Pocket-Sized FM Fury: The MVAVE FM-1 Reviewed

TAETRO rolls up with the MVAVE FM-1, a synth so tiny you could lose it in your hoodie pocket. Don’t let the size fool you—the FM-1 packs a decently sized screen, a built-in speaker (about what you’d expect for the price), and a surprising selection of ports. USB-C covers MIDI, charging, and audio, there’s a headphone jack, and a 3.5mm MIDI socket. It even boots faster than a Roland Aira—no time for tea breaks here.

Connectivity is the FM-1’s hidden weapon. Plug it in, power it up, and you’re off. Sure, the speaker won’t win any hi-fi awards, but we’re not here for audiophile fantasies. This thing is made for quick jams, instant ideas, and setups where space is as tight as your budget.

Scroll through the presets and you’ll hear a fair attempt at classic FM flavours—some hits, some misses, but plenty to keep you busy. Editing goes deep enough for FM nerds, with six operators, 32 algorithms, and full parameter access if you fancy a menu-dive. The effects section is basic but functional: reverb, delay, chorus, phaser, distortion, and a simple filter. You can rearrange the order, but don’t expect Eventide magic. They’re serviceable, but won’t make you ditch your favourite pedals.

The built-in keys? Let’s just say they’re more ‘novelty’ than ‘performance’. Spongy rubber and close together, they’ll trip up anyone with fingers bigger than a toothpick. Plug in a MIDI controller if you value your dignity. Still, for quick sketches or showing off at the pub, they’ll do in a pinch.

The FM-1’s arpeggiator is as straightforward as it gets: rate, direction, gate, swing, random mode if you need some chaos. The sequencer, meanwhile, started basic—just 16 steps, no rests or ties, and you couldn’t switch patterns on the fly. But here’s the kicker: a firmware update landed mid-review, adding long notes, sequence chaining, voice-per-sequence, and variable step lengths. That’s a rare win for a budget box.

It’s still not Elektron-level, but now you can chain patterns, get clever with sequence lengths, and even change sounds per pattern. No real-time overdub, no advanced song mode, but for a synth this cheap, these updates are proper progress. If you care about tight workflow, you’ll want to keep an eye on further updates—this toaster-fight isn’t over yet.

Here’s where the FM-1 starts flexing: Bluetooth MIDI. Forget cables—pair it with your iPhone or iPad and suddenly your pocket is a rave bunker. The FM-1 handles both MIDI in and out, so you can sequence it from an app, or use it to control other gear if you’re feeling wild. Tiny synth, big ecosystem.

Of course, no gear is perfect. The USB audio implementation is a bit odd—plug in and the speaker keeps playing unless you use the headphone jack. Volume controls affect both outputs, which is a head-scratcher. Still, Bluetooth MIDI is a killer feature for on-the-go jams and mobile rigs. If you want a synth that thrives in a bag full of gadgets, this is it.
