I can't go over all the features, there are too much, here's a list of which I use and how I use themĪLT 3/4 -> to send in the looper, coming back in a stereo channelīuiltin effect unit, mainly for reverb, with option to send the effects into the alt 3/4 (to have effects inside the looper, however the effects bleed into it) or only to main mix (with zero effect in the looper and therefore zero bleed) In terms of outputs, I got surprised by the fact the main outputs are only XLR cables, but after a second thought it doesn't bother me at home since I record from USB and send to my home speakers via RCA, and for a live setting having an XLR output is the better option. I also didn't expect it, but you have some degree of control over each effect by being able to tune one or two parameters per effect. I mostly used reverb so far, and it's great. I was pleasantly surprised by the quality of the built-in FX unit. Double AUX send: one AUX send and one FX send, both with returns, offer quite a bit of wiring options. Compressors for the mono channels do an okayish job if you don't need real control over it. The sound quality is good enough for recording, I'll maybe edit this feedback once it will be tried in a live setting. Allows us to play live with several channels and I can just pick one or two to record and loop while the others are left unchanged.

The alt bus is the feature I was looking for the most, to be able to allways choose whether to send a channel to record with the looper. I also play sometimes with a friend who has a modular synth and me with semimodular + looper. As a project, I play with an acoustic guitar, a small semimodular synth, and a loop pedal.
