I got the Tracker a couple of weeks ago, and thought I would throw in my thoughts, as they include some observations that I haven't seen shared yet. I got into electronic music from using LSDJ on the Game Boy, so this more fully featured tracker device instantly appealed to me. On top of this, I am a bit of a sequencer nut, and have a Digitakt, Pyramid, Monome, etc - so a fair bit to compare it to.
First of all, the Tracker is beautiful. The screen is really clear; the controls smooth and (largely) intuitive. A lot of thought has clearly gone into it, and making music is extremely easy and accessible. I like it a lot. I rarely make full songs on grooveboxes any more - opting to do sections and then record them into Logic for production, given the various different pieces of gear I've got, and how much of a pain it can be to get them to all talk to each other. However, the song arrangement feature on the Tracker is nicer/more capable than expected.
Some other positives:
* I love the FM radio capture feature.
* Even though Tracker doesn't have multiple outs, it allows you to render stems as wavs for export. This is an awesome feature, and I don't get why Elektron didn't introduce this to the Digitakt, rather than rely on OverBridge (which I've never forgiven them for announcing along with the hardware and taking 2 years after that to deliver).
* MicroSD card storage is brilliant. It is such an obvious, good solution to sample space. (ARE YOU LISTENING, ELEKTRON?!)
Some negatives/areas for improvement:
* The Tracker has less modulation/FX options than the Digitakt, which is a bit disappointing - as a bunch of these could surely be easily implemented to give greater dynamism.
* The internal RAM(?) gets used up quicker than I would like. Not terribly so, but there's still less space than I might want for full in-the-box songs.
* Stem export is pretty buggy. When I first got Tracker there were all sorts of audio glitches, and there is an outstanding bug where the tempo of the exported stems is messed up/drifts. That kind of kills that feature's usefulness.
* It would be great if there was room for extra tracks to run simultaneously. I'm not sure of the hardware/technical limitations here, so take that with a pinch of salt.
Generally speaking, I really like the Tracker. It's a great device with a couple of implementation flaws which I am sure will be fixed. Polyend have been really quick to reply to e-mails and pick up on GitHub issues (even just having the ability to submit a bug report this way is good), and also share beta builds via the GitHub repo. All of this is great, and I look forward to seeing how the software develops. At present I am mostly holding out for the stem export fix, as having the BMP messed up throws a spoke in the wheels of my usual workflow.
