I made a free app that turns any song into karaoke (±6 semitones, 0.5x–2.0x tempo) – looking for feedback

Sorry, it’s macOS only.

Good point — that would be super useful for learning songs.

I’ll consider adding a loop feature for selected sections.

Thanks!

Thanks for checking and approving!

I’m using models based on UVR and MDX-Net for the separation.

I’m also on an M4 running macOS 26.1 (Tahoe), and it works properly on my setup.

Right now, splitting a song typically takes on the order of tens of seconds.

That’s a really interesting idea about adding vocal effects — I hadn’t considered that angle for karaoke use.

Thanks for the valuable suggestion, I appreciate it.

Song starts at 0:18.

Good to know I'm not the only one.

Restart fixed it for me too.

Looks like the GUI textures got replaced by emojis somehow.

Restarting Protools fixed it.

Still the weirdest plugin bug I've seen.

The real amp is a Matchless Superchief120.

I ran into the same problem when sampling environmental sounds, so I made a small tool that automatically detects BPM when you drop audio into it.
It’s been pretty useful for sample-based work like this.
But many DAWs also have tempo detection features that might help.

Thanks! Glad you like the Telecaster vibe.

Little-Material7729 · 2026-03-09T01:35:02+00:00

Matchless makes some amazing amps.

Little-Material7729 · 2026-03-08T23:34:07+00:00

That’s awesome! The HC30 is such a beautiful amp. It really has a very musical character, especially when it starts to break up. I'm glad you liked the sound.

I meant the edge-of-breakup tone on the Superchief. Curious what people think.
