Metamyther’s Stem Ripper vs 8TR: Eurorack Stem Recorders Go Head-to-Head

Metamyther dives straight into the thick of it, pitting ALM’s Stem Ripper against Halftime Modular’s 8TR. Both modules promise to make stem recording as easy as falling off a log—no external gear, no spaghetti, just plug and play. The comparison is clear: these are the Zoom L6’s modular cousins, built for capturing your best jams right inside the rack.

The intro sets the stage for a proper head-to-head, with Metamyther’s industrial-tinged delivery keeping things brisk. If you’re after a stem solution that doesn’t involve dragging a field recorder to the club, both modules are already looking tasty. But as always, the devil’s in the details—and that’s where this video starts to dig.

Both Stem Ripper and 8TR are designed for people who want to get recording with minimal faff. Eight inputs, a single record button, and SD card slots—this is as idiot-proof as modular gets. The expander modules spit your channels back out for monitoring or routing to a mixer, so you’re not stuck guessing what’s actually going down.

Metamyther points out that you just hit record and you’re off—no menu-diving, no firmware-induced rage. The 8TR even throws in a trigger input for beat-synced recording and comes in a 1U flavour for those who’ve run out of HP. Both modules are clearly built for the live crowd who want to capture the moment, not lose it in a menu maze.

Here’s where things get spicy. The 8TR is 2HP slimmer than the Stem Ripper, which might not sound like much, but in Eurorack land, that’s the difference between smugness and regret. The 8TR’s trigger input on the expander lets you sync recording to your set—perfect for live looping or tight transitions. And if you’re desperate for space, the 1U panel means you can squeeze it into even the most claustrophobic racks (though you’ll lose expander compatibility).

The Stem Ripper fights back with a red clipping light—handy, but it only tells you that something’s too hot, not which channel is melting. Meanwhile, the 8TR gives you green activity LEDs per channel, so you know what’s actually coming in, but no per-channel clipping. Both modules record to SD cards, and both ship with one—nice touch, even if you’ll probably swap it for something bigger.

The real kicker: Stem Ripper records at 32-bit, 8TR at 24-bit. The 8TR has a wider voltage range and a lower noise floor, plus it’s chainable for those who think eight channels just isn’t enough. Each module brings a few unique tricks, but you’ll need to watch the video to see which quirks matter most in action.
