Actually it's not a big deal to implement it, the only real problem I'm facing is the layout. I think I'll use a "stacked" mode (similarly to what MonstrumFeld uses) that will hide the effects and arpeggiator panels and show the matrix in their place.
I was afraid of that. Could you please send me a screenshot, so I could better understand where the problem might occur?
You are ideally right. But. Python 2 choice is just for laziness, I am not a programmer and I actually don't have much time to dedicate to it, so, even if I know that there's not so much difference (and, actually, a lot of advantages), I didn't find it so impelling.. I prefer to dedicate my time to a (yet still valid and supported enough) pair of language/toolkit I already know.. and play my music in the remaining time ;)
About Qt5 the problem is that right now I don't have it and I can't install it, for various reasons I won't debate here.
That's good to know.. I only could try its demo on VirtualBox, I was satisfied with the whole interface, but I felt it wasn't right for some things, and Ctrlr is a bit clumsy sometimes.
Anyway, I'm glad you appreciate it, I'm really looking forward to finish it..
Cheers!
