Re: [Freecycle-users] midi export and libinstpatch bug fixes

[Predrag Viceic]

Hello Brandon,

 

That's a wonderful news.

 

The hardest part to implement in Freecycle was the interface management with Qt3. From memory, Qt3 canvas didn't support floating point coordinates and has no elegant way to handle zooms-dezooms-scrolls in a large set of data. Therefore I had to re-implement a large part of this.

 

When I've started porting to Qt4, I remember that displaying a loaded waveform (with zoom-scroll, etc..) was done in 1-2 days time and it worked well. All the linear algebra stuff was handled by Qt and all I had to provide was the coordinates of the samples.

 

I think that you'll be able to get very fast something running :)

 

Anyway, don't hesitate to ask questions on this list if you get stuck. Please keep us informed when you make public your Github repo!

 

Very best,

Predrag
