yeah they sound very different… even a clean sample with default settings (open filter) gets some noticable color on the Rytm (this is not audiophile mumbojumbo - it really is immediately noticable). If the sample volume is above something like 60 I think, there is already some soft overdrive happening… the overdrive sounds very, very different, as does the filter.
On the Digitakt, everything is a lot more clean, including pitching a sample up/down and the bit reduction effect.
Dunno, but it seems the digital sound engine in DT runs on higher bitrate/samplerate internally…? it’s also quite noticable on the delay/reverb FX.
It’s far easier to get gnarly, crunchy raw sounds from samples in the Rytm, and far easier to get cleaner hi-fi sounds from Digitakt.
(haven’t done a one-to-one comparison with the same sample on both machines yet - would be interesting to see it in a 'scope)
