Subbz2k pretty much sums it up.
Not had any gain structure issues with mine however, tho, I am running into an RME Fireface UFX.
The 2 machines are chalk & cheese & compliment each other very well.
Some say the MD Kiks lack bottom end but if you look at an analyser with say the EFM or TRX B2 machine you’ll see gobs of sub, it’s just very low, say 90 down to 50 hz.
The RYTM has more low mid, around 160hz so on studio monitors it gives the impression of more bass.
RYTM is invaluable for polyrhythms, ReTrig, performance functions, mute mask & being able to blend a sample.
MD is glitch heaven, ram machines, ctrl all, 16 LFO that can be freely assigned anywhere, the list goes on, it’s a classic
