Arturia Mellotron V 1.9.3 — Mac version

Arturia Mellotron V is a software take on the Mellotron keyboard, built as a 64-bit plug-in you can load with your own samples.

Formats — VST, AU, and AAX. It's a 64-bit plug-in only, so it will show up in any modern DAW that runs on macOS 11 or later. It works on both Intel and Apple Silicon machines.

Sample loading — You're not locked to the factory sound. Each track can hold up to two factory samples, eight of your own, or a two-plus-six mix. The plug-in reads WAV, AIFF, and FLAC files — no arcane conversion needed.

Sound shaping — An ADSR envelope sits alongside dedicated mechanical, noise, and tape controls. You can push the flutter, scrape, and hum until a clean choir pad sounds like it's been living in a damp church hall for forty years.

What's new — Version 1.9.3 tidies up the preset browser. Favourites management, naming, and search all feel quicker. One practical tip: if your playlists ever disappear, removing and reinstalling the instrument brings them back.

Shift-drag samples onto a track to snap to semitones

Double-click a track name to rename it instantly—no menu diving. Hold Shift while dragging a sample onto a track row and it snaps to the nearest semitone, which saves fiddling with the offset knob later. Right-click any knob to return it to its default value. The tape-age slider works in tiny increments if you hold Command while dragging, giving you fine control over how knackered the tape sounds.

The preset browser search field accepts partial words. Type "bass" and you get every preset with bass in the name or tagged category, no need to remember how Arturia capitalised it. Favourite presets now sort correctly with shuffle on, so random browsing through your shortlist actually stays random.

Loads in under two seconds on Apple Silicon

On Apple Silicon the plug-in loads fast, usually under two seconds even with a full tape bank. Intel machines take a beat longer—maybe four or five seconds—but once it's up there's no perceptible lag switching between tracks. Memory use sits around 400 MB with a modest set of user samples loaded. Push it to eight custom tracks per row across several rows and you might see 800 MB, which is still reasonable for a sample-based instrument.

CPU hit stays low. A single instance playing six-note chords rarely nudges past 8% on an M1 chip. Stacking four or five instances in a busy project will start to show in your CPU meter, but freezing tracks sorts that quickly. The tape flutter and mechanical noise modelling run on their own thread, so cranking those up doesn't choke playback.

Stability is solid in Logic Pro and Ableton Live. Older Intel machines running Big Sur have thrown the occasional UI glitch where the tape reels stop spinning visually, but audio keeps going. Quitting and reloading the plug-in fixes it straight away.

Playlists can vanish after an update

Playlists vanishing after an update. This one catches people out. The fix is simple: remove the instrument, reinstall it, and your playlists reappear. Arturia sorted the underlying bug in 1.9.3, but if you skipped a version in between, you might still see it.

User samples not mapping correctly. If you drag in a WAV and it spreads across two semitones instead of one, check the root-note metadata. Mellotron V reads embedded pitch info. Your sample might be tagged as C3 but the track row expects C4. Rename the file with the correct note or set the offset manually.

Silence when loading a project. Sometimes a DAW recalls the plug-in state but mutes the audio engine. Toggle the track's mute button twice, or delete and undo the plug-in instance. It wakes up. This happens more often with the AU version in Logic; the VST in Live seems immune.

High noise floor on old presets. That's not a bug. The mechanical noise knob defaults to about 30% on many factory banks. Dial it back to 5-10% if you want cleaner pads. The tape-age control also adds hiss—zero it out if you're after a modern sound.

Favourites not sticking. Before 1.9.3, marking a preset as a favourite during shuffle mode would sometimes lose the tag. That's fixed, but if you're on an older build, disable shuffle before favouriting anything.
