Since Elektron seems to love making new things vs. updating old ones, my feature request would be one more bugfix and THEN:
The Dodecatrack (DDT): 12-track flagship sampler with DT-style hardware, improved workflow, threshold sampling, more RAM, SSD sample streaming, conditional trigs, 12 -track midi sequencer, etc, etc., etc.
Edit: And of course, proper muting that preserves FX tails.
