A couple of random thoughts in no particular order:
I’ve been through many different setups of vintage analog and digital synths, vintage electric pianos, some eurorack, the Octatrack, and several different DAWs, and I still find that I get most of my productive song construction done in Ableton.
I’ve moved a couple of times and did some massive sell offs – which I ended up regretting and re-buying some of the same equipment later. What I’ve realized is that for me, having a couple pieces of hardware that inspire me and (crucially, I think) push me to work in somewhat obtuse or different ways than Ableton or other DAWs might, helps me to create more interesting “building blocks”. But I always end up organizing all of the components and the final track in the DAW.
From a hardware perspective, I think finding a streamlined set of gear and really sitting down and developing a workflow with it has helped me the most. Before, especially when vintage gear was cheaper, I was constantly rotating equipment and never really learning how to use any particular piece of hardware in a compositional sense. I might have a full technical understanding of how to program a particular synth, but I never worked to actually make anything with it. It was more about the feature set and the sounds it could make than actually developing my ability to make music with that tool. The only constant tool during this time was Ableton, which might be why I find myself returning to it for the construction phase.
For whatever reason, I’ve never been fully satisfied with a totally software setup. I think a lot of it has to do with my background as a keyboard player before getting into electronic music – something about the tactility of an instrument “clicks” in a way that I haven’t been able to recreate with software alone. However, the times in which I had the largest quantity of hardware were actually my least productive by a significant factor. There were years when I was surrounded by keyboards and made no music at all. It was a case of analysis paralysis; too many options made it daunting to even get started.
