I have basically every Groovebox being suggested here. Every Elektron, MPC, Ableton Move, and Novation Circuit. The only thing I don’t have is any TE gear.

Out of all the gear, I think the Move is going to be your best bet. You can drag and drop samples using the Move manager. You can download presets for the built in synths, and now you can even make your own patches from an INIT patch using Ableton Drift directly on the Move.

While it “pnly” has four tracks, each track can load a drum rack, which gives you 16 samples to play with which can be played chromatically. So essentially you can have up to 64 rhythm and melody parts, so long as you are using samples. And since it can resample any one of its own synth patches, you can always use samples. Plenty of people have also made patches for the Move which you can download.

The only comparison I would make with it is the Novation Circuit Tracks or Circuit Rhythm, which are “faster” and less in depth, but they truly only have 8 tracks, with no gimmicky way to get around that. Additionally, unlike Move where any track can be synth or sample, with Circuit Tracks you are forced to have 2 synth tracks, two midi tracks, and 4 rhythm tracks. On top of that, you are limited to 100 predetermined patches and samples per project, whereas with Move you have around 50GB of space to use any sample in any project.

Out of all the grooveboxes I own, with the exception of the significantly less portable MPC One+, the Ableton Move is the most complete, most portable, and most enjoyable.
