The sample doesn’t steal the synth voice from the track that it is on so you can layer them BUT on the tracks that share a voice you cannot have a sample play on both so those tracks do steal from eachother. I just got an octatrack. I really like it but the rytm is more instant and also makes better drums than most samples I’ve heard. Plan to run my octa through the rytm to take advantage of the master (side chaining) compression… Also have an A4 but mostly plan on resampling that into octa for live use w/o bringing the a4 just b/c I only have 2 hands and want a more minimal 2 box set up
