Yesterday, I found a feature that's even greater than the above-mentioned one: time scale set to '64, 1/4' in combination with micro timing!! (and I'm not that poly-rhythm kind of musician..)
Before elektron, I preferred to use 16 bar loops. In my opinion, 16 bars are the perfect unit to structure electronic music, e.g., 1x (or 2x, but that doesn't make much difference here) 16 bars intro, 1x 16 bars theme1, 1x 16 bars some more action, 1x 16 bars theme2 etc. with some cymbal hit in the beginning of every 16 bars and some BD/SD variation in the end. With the elektrons, I switched down to their 4 bars. This seemed quite restrictive to me. Sometimes I tried to go back to 16 bars via pattern chaining, but that's not the same (for instance, because you can't easily copy&paste between different patterns during playback and need a large amount of patterns).
Now with that '64, 1/4' time scale, patterns can have a length of 16 bars WITHOUT losing any rhythmic details thanks to micro timing and maybe some retrig p-locks! Imagine a chain of 4 patterns that have a length of 16 bars each and a bank with 4 of those chains. That's really a lot of space for variations! (easily enough for a complete track, where you can even record all automations)
And if you need one track with some very crazy weird rhythm, e.g., percussions or a melody, you can set this one track to the usual speed of a '1/1' time scale thanks to individual time scales.
NICE
This feature might be interesting for anybody trying to build full tracks on the OT.
