Since I have both now, I thought I would load the same sample into each and record the output as a test. This is a short clip of a song from a CD, sent to each machine using the Transfer app (not recorded into the Digitakt). I matched levels as close as I could, then after recording I normalized to -3dB in my editor so the transient peaks would be the same. The track on Model:Samples was set to Volume 60 (supposedly max before distortion).
The first in this example is the Model:Samples, followed by the Digitakt. When I was listening live I thought they sounded pretty much the same, maybe a slight difference but I couldn’t quite pinpoint what it was. But when I looked at the waveforms in my editor it seems clear that the Model:Samples is a bit compressed. Maybe Elektron included the compressor from the Digitakt, but just has it set up for lite compression all the time? There’s no menu option for it unless I’m missing something. Or maybe it has to do with the Volume control - maybe a level of 60 is still hitting the overdrive a tiny bit?
