If you’re going to keep both, might I suggest also using the 8 DT midi tracks to sequence 8 channels of the SP-16? That way you get the best of both worlds.
I have a DT coming today for just that…
On the DT will be mono percussion and noise samples, sequenced internally.
On the SP will be all stereo samples/loops made from other gear, triggered by the DT midi tracks (to get different track lengths, probability etc) for tracks 1-8.
Then tracks 9-12 will be one shots (manually triggered or sequenced in the SP) and 13-16 will be long non-rythmic loops set to loop indefinitely until muted.
I know mine is a very specific use case, but the features of the two combined basically make a sampling groovebox dream machine.
