I just wanted to inform about Psycle - an oopen source sequencer for Windows. There is also a QT-version wich uses QT4, and which runs on Windows, MAC, and Linux. The development of Psycle has been very slow for several years because of lack of developers.

Sorry, but I can't program just now because I have no knowledge about VisualStudio.
More information is at...
