From what I understand - you made x8 different samples on the tb-303, with 8 slice divisions per sample.
Then reorganized them so that the resultant samples would have:
R1 - a1,b1,c1,d1…h1 ; R2 - a2,b2,c2,d2…h2 ; R3 … R8.
Then what did you do with the resultant “MatrixMixed” samples?
Did you slice each resultant sample in the OT up into 8 slices - assigning them to individual OT Tracks - T1 through T8? Or did you assign them to 8 individual trigs on a single Track of the OT (Lets say Trigs 1-8 on Track 1) and then assign the cross fader to change start position when transitioning to a new scene, etc.?
