Announcing CMKeyboard - Clutter MIDI Keyboard
http://djcj.org/cmkeyboard
CMKeyboard is a 128 note ALSA MIDI virtual piano keyboard spanning from
C-1 to G9 written in python3 and taking advantage of the latest Clutter
(>1.12.2) features to enable scrolling and opengl goodness. It is a stand
alone program which can also be embedded into other python3 applications
as a class library. It uses code from the very handy pyclutter-widgets
project for the rounded rectangles of the key buttons.
The code demonstrates use of Clutter.ScrollActor(), GtkClutter.Embed(),
layering of multiple clutter actors, handling of events including:
"button-press-event" & "key-press-event".
Suggestions for features and improvements welcome.
Enjoy!

Hey Patrick!
In what way would you say this is different from JACK Keyboard?

First it uses alsa midi through the alsaseq library.
Second it is written in python3.
Third it uses the Clutter "opengl" UI toolkit.
I'm not sure if jack keyboard supports 128 midi keys.
CMKeyboard is not intended to replace jack keyboard. It's about getting
some traction using Python3 and Clutter.
Clutter and Python are two under utilised options in LAD. Not sure why
Python is not so popular considering how many professional and highly
successful AV projects have been built with it but Clutter seems to have
been off the radar for a while. Maybe now that the new touch interfaces
are arriving in the market this year we will see a pick up in Clutter
projects for LAD applications.

Patrick, interesting stuff! I am about to push an early version of my current project to
github -- python and clutter implementing a puredata knockoff (with python data types and
evaluator).
I've found it to be a good combo so far, using multiprocessing to separate engine, UI,
and DSP (in C extension).
Thanks,
Bill Gribble

That is my experience with the combination too. I have also found it works
nicely as an addition to a gtk3 interface using the embed() option. That
gives a gtk3 wrapper with direct cairo support while allowing easy access
to clutter, opengl and the advanced gesture and animation support. It's a
pretty powerful combo.
One thing I am still working on is getting direct access to the GPU for
additional processing grunt.

I have done some proof of concept tests with pyopencl that look interesting.
There are practical problems: you add a whole other "domain" to process in, in
addition to Python-world and Jack-world. You have deployment issues with the OpenCL libs
for different GPU vendors. The wide SIMD architecture of GPUs is really only helpful for
certain audio ops like convolution, or very wide banks of identical processing. And if you
are using the card for graphics, there may be unpredictable interactions.
Still worth exploring though, and a "cl~" processor for my system is definitely
on the todo list.
Thanks,
Bill Gribble
