Collidoscope...A Granular Audio Synth

I was watching random videos and stumbled on this one by Dr Mix.  (this is their prototype, not my version)

So I thought it had a great look and interface, but couldn't imagine how expensive it was.

...it isn't...

This was a project by two people (I assume students at the time) at The Queen Mary University of London.

It operates of a Raspberry Pi, two USB/MIDI keyboards, 4 slider potentiometers, a Focusrite USB soundcard, an arduion Teensy, two microphones and a monitor. 

To make it pretty you build a box.

Their project site has full documentation on the wiring, software, and even hardware.

there are a couple of howevers.

-First, the software was last updated in 2016.   They have a compiled app at the project page that works just fine, but if you want to make any changes...well lets just say I have been neck deep in software for the last few days.
-Second, most of the pictures and explanations show the original version, the plans demonstrate the later version...can cause confusion.


So a big part of their project was the Collaborative concept of separate keyboards, microphones, and sample manipulation.

For now I am simply building a single person version...so I only have to source half the hardware from ebay...
...but I had to modify the software...

If you notice in the video,  you see two wave forms...but they are both on a single monitor.   I wanted to make a single user version and only show one waveform on the whole screen.

If I had done this back in 2016 it would have been a simple text edit and recompile.   However, the compiling code changed quite a bit from then and it was far from a simple text edit.
