Filters and keypads

Right, well the "FX" chain of the Acid line is going to pass through distortion and a filter. Finding small/cheap things to cram into a box at some point is difficult and a little expensive. However, in terms of keeping everything as components to break out for future projects, and for other use, I finally had an excuse to buy a Monotron.

I want the MS-20 filter for this project, and it has audio in to do that, but having just had a noodle around with this it's a cool piece of kit in it's own right. Plus it's small, light, and battery powered. Need to test it properly but here it is fresh out the box.

In terms of controls, firmly set in the idea of a numeric keypad now, but I had some headaches with the first one (a little bit self induced) but anyway I've gone in for a slightly odd pad found on Amazon that has no numlock but instead has a tab button. I can easily map all of these in Python using curses and it's leading me down a minimal design for data entry and UI navigation.

I've made a sheet in Google docs to start to map out the functions, here's the template, waiting for the post to turn up and to actually try the pad, hope it works with Linux.
