Yeah it is possble to send samples from MDUW to Rytm, just make sure to connect midi out to midi in both ways (closed loop) so out from MD to in on Rytm, out from Rytm to in on MD, on MD go to globsl slot sample manager and send from there. You can also use other samplers to send, as long as they support SDS, I have used a Yamaha SU10 for both MD and Rytm, works great. Just be patient as fast it isn’t
