I’ve found that while pattern chaining does work for me when im using the digis, I was surprised at how much the song mode on my Tracker changed my creative perspective when fleshing out a tune. I’ve found it difficult to make varied B sections of a tune on the digi boxes but it came very easy to me when working in the Trackers song mode. I think its the way that everything is laid out and can be seen all together, it helps me realize what could be next rather than being stuck in a loop.
I’ll also add that I am not someone who enjoys arranging and tweaking something in Ableton (for better or for worse) so its nice to keep everything in the box so to speak.
