Cool! Sounds super smooth.
I’m running a similar setup with my TR8 going through Arturia Microbrute. MB’s overdrive (“brute factor”) goes from subtle to Extreme and has a very distinct sound. I personally love it. The filters are also lovely.
Here’s a demo with the TR-505 (not mine). Not enough tweaking but you get the idea. https://www.youtube.com/watch?v=y0yr5efv7Q4
Anyone using a drum machine should consider a setup similar to these. It really makes a huge difference. Plus you get an analog synth!
