I've been moving along nicely and have pretty much all of the network functionality up and running.

I started to work on the Music Maker functionality and soon ran into a problem: Insufficient RAM and flash on the Feather 32u4.

So I've switched my build environment to the Feather M0. I'll implement the majority of the logic and, if it fits comfortably in the M0, will then order one.

I haven't really had to worry about space constraints since the mid eighties when I was still working on PDP-11s  ;-)
