OP-XY: tools, mods & resources

Beyond the usual marketplace caution (use buyer protection on Reverb/eBay, beware too-good-to-be-true deals and stolen units), test the things that are expensive to fix. Exercise every key and encoder for dead spots or crackle, check the screen for dead pixels, try the headphone and line jacks, and confirm it charges and holds a charge. Make sure it powers on, takes a firmware update, and isn't iCloud/account-locked or reported lost. New units come with a warranty, which is worth weighing against the second-hand saving.

Not as a built-in feature — the dedicated multisampler is an OP-XY thing — but you can fake it. Record several different sounds (up to ~20 seconds each) across the four tape tracks, loop them, and use the multi/copy trick to spread them into a playable instrument. The OP-1 field and OP-XY are believed to share the same hardware (around 24 voices), so the limitation is the field's software playing one instrument at a time rather than the chips — hence the tape workaround rather than a true multisample patch.

A screen that sits very slightly off-center is common on these devices and falls within normal manufacturing tolerance — it's purely cosmetic and doesn't affect the display or how the unit works. Unless it's dramatically misaligned, has dead pixels, or the glass is lifting, it isn't usually worth the hassle of a return. If it genuinely bothers you on a brand-new unit, that's a reasonable thing to raise with the retailer, but don't expect a "perfectly" centered panel.

A few options come up repeatedly. Teenage Engineering's own case is slim and fine for light protection; for tougher travel duty, owners rate the Analog Cases OP-XY case highly, and generic small hard cases or camera bags that fit the unit also work. Precision-cut third-party cases exist too (see TEcases in this list). Pick based on how much impact protection you need versus how slim you want it.

The reliable approach is to record each track on its own. The OP-XY is a class-compliant USB audio interface, so connect it to your computer and, for each track, mute everything else and record that single track's output into your DAW in one pass — repeat per track to build up stems that line up. Keep transport and tempo consistent between passes so the stems stay phase-aligned, then assemble and finish them in the DAW. It's a few passes rather than a one-click export, but it gives you clean, separate tracks.

Yes — hold the mute/shift modifier and tap a track button to mute or unmute that track, so you can drop parts in and out by hand. For arrangements where you want the muting to be part of the song rather than performed live, build it into the composer: make pattern variations that include or omit specific tracks and switch between them. Between live muting and pattern variations you can get most of the "drop the drums, bring them back" control you're after.
