Mostly looking to build a DIY Rack to play mostly leads on from my keyboard controller via midi. Not looking to do ambient, sequencing or generative type stuff -- just more for playing leads. Mostly want to explore creating my own sounds [not so much interested in already made/sampled sounds...have enough of those] and play crunchy-ish leads. I'd like to eventually build up to a 9U rack but figured I'd take it 3U at a time. Some of the models [like the poly] are to support that eventual goal. The power and switch would be built into a DIY case so not including those as a front panel piece. Although I needed to fill 1u so threw in a power indicator led. I have quite a bit of experience in electronics so want to build most of the modules myself. Given all that -- any opinions on this rack? Anything fundamentally wrong here? Thanks!
