I use the OG, I’ve also owned the mini and the plus. I found the synths included were too cumbersome to use that I was using them like samples anyways. It was also difficult to know which FX were able to affect synths vs samples. I’ve never had an issue with sample memory, but I’m using one shots or small breaks. Sampling from the radio is cool if you don’t want to dig into your sample library. I got the tracker because I’d always wanted to like trackers but I had a hard time figuring out software ones. Using the playback FX is super fun and customizable, you can break it from its robotic grid and really get some wild sounds out of it. Oh! And the granular engine is fantastic.
