A few thoughts about the LXR-02 and the Syntakt, maybe that is of some help:
The LXR-02 has 4 outs if that is important to you, because most of the other machines mentioned here have only 2, but the machine drum has 6.
Sequencer is good, but you can only p-lock 2 parameters per sound, so if you routinely lock more parameters per sound, you’d have to use an external sequencer and send CC (that’s what I do). Since LXR-02 receives all parameters for all tracks on a single MIDI channel, a substantial amount of parameters are only available via NRPN. I found most of those are not parameters I’d like to automate anyway. Which is good, because the sequencers I have at hand can’t send NRPN.
Also, you can’t copy individual sounds between kits. Even if you’re prepared to wrap your head around the algorithms and create all your kits from scratch, that might slow you down a bit, because you can’t just spend some time with the machine to create lots of sounds, and mix and match those later into kits for your tracks.
To actually copy a sound, you’d need to write down around 40 parameters scattered over 12 or so pages on a fucken piece of paper. I did that once. Can’t recommend. Won’t hold my breath for an update to remedy that, either.
Sound is amazing, though, a really nice touch are the sampled transients, you can do a lot with those. Though I must admit I’m still pretty far away from being fast with it.
Syntakt is a much smoother ride, it’s so easy to learn from other people’s sounds because you can easily browse sounds, and if you find something interesting, it’s easier to see how it’s done because you can see 8 parameters on a page, the LXR has a smaller display that shows only four.
Editing on the Sytakt is fairly simple with 8 encoders, on the LXR it’s noticeably slower.
Also, Syntakt algorithms are much more straightforward, since they offer only 8 parameters per algorithm, LXR2 has a lot more parameters, but only 4 algorithms, which are hardwired to tracks, you get 3xDrum, 1x HH, 1xSnare and 1x Clap/Cym, and there’s no way to change that.
One other thing I really like about the Syntakt is the modulation setup for Mod Wheel, Breath Controller etc. It’s so easy to add expressive modulations to a sound with a simple MIDI controller, there’s no way that can be achieved on the LXR-02 without extra hardware.
