Yeah, should work with anything really! Just take the cables out of ‘from device’ on the Audio-8 module, and connect to a sample player, oscillator module or anything you want. I’ve got an old Juno 6 which I’ve plugged through a few guitar patches, they don’t always sound as good as you’d think. Maybe it’s because all my patches are kind of ‘tuned’ for guitar, and it’s a much more narrow frequency range than synths, but ultimately it’s just effects so still works. Enjoy!
