  I started a tcl-tk piano-roll project, with no knowledge of tcl-tk 
language, no one proposed to help, no one did care, I stopped the 
project because the external toxy for building widgets is not any more 
developped

I've also tried to make one with tk-inter with using pyext, is rather 
horrible, even more difficult than using toxy syntax.

I've learned a lot about data structure, it's crappy for drawing but not 
for sequencing (because it's faster than any message system), it's even 
the best thing in pd for sequencing messages, without using the old MIDI 
midi protocol as it is handled by pd internal objects.

I believe that it would be possible to make something good with using 
Gem for interfacing the sequencer, data structures for sequencing 
messages, I'll try to waste my time on this as well.
