I would like to share my little keyboard abstraction.

Visualizes MIDI notes in and sends out MIDI out from computer keyboard (polyphonic) and mouse. Tested and fully functional on Windows 10 with Purr Data 2.5.1 but sadly the overlapping scalars where very glitchy in vanilla so I did not bother fixing it.

I almost forget to thank @Jona for the pointer list patch and special thanks to @corvett for the repeated key fix:

@nuoun Thanks for sharing it. In Pd 0.48-1 vanilla I'm getting lots of errors from the [pd init] subpatch as you can't have $0 variables in message boxes, and therefore you have to do it thus instead:

In Purr data you can have that, but not in vanilla, so perhaps it's worth keeping in mind if you want your patches to work on both systems.

Thanks for the reply, I was aware with the $0 thing being purely Pd-l2ork but habits die hard, the reason I did not bother fixing for vanilla is that the overlapping scalars have a layering problem at least in Windows, what happens is that when one of the scalars gets [set] it places it on top of the other ones and I'm not sure how to fix that without making the patch a lot more complicated.

@nuoun Fair enough, if the patch wouldn't work in vanilla anyway there's no point in fixing it. I just thought I'd mention it in case you weren't aware of it.
