The Tracker is great BUT it does have some quirks and limitations that still are frustrating because it is like 75% of the way there. For example, adding certain effects or parameters to samples (like chorus) are 'additive' and take a while- then if you don't like what you hear, you have to scrap the altered sample and start over again. So, there are some things that I'll say aren't great. But if you are into more dnb/glitch/EDM or any heavily-sample based music, it's totally worth looking into.

Probably too close to the M8 but Polyend Tracker Mini is a smaller version of the Tracker but more portable and battery powered.

Korg Prologue (8-voice), Polyend Tracker (for drumz and sample mischief), Elektron Model_Samples (because for portability and messing around, it's the easiest) and now I just purchased a Syntakt. Run stuff into a mixer>interface>FL Studio. Sometimes I will also plug in my G&L Fallout guitar and make guitar sounds and play with those as well. Also have a Novation Circuit (OG) floating around that I admit I still love, despite my hate for Components. I've been trying to streamline my pedals down to what I NEED, but you know how that goes...
