Originally I thought the Rytm synth engines sounded a bit meh, but then I heard the excellent AR808 sounds.
This inspired me to work a bit harder on the synthesis side. My preference is now to use synth over samples for kick, snare, rim, clap, hats. Open hat I layer with a sample, and same or cymb/rides.
As for alternatives, Jomox sounds are so sweet, but people’s experience with the unit quality and software keeps me away.
