I went back to the Amiga to create music in Bars&Pipes and thought it would be a great idea to just run WinUAE. Speed and memory was of course not a problem; my AMD2800+ was the fastest "Amiga" I had ever seen. The problem was the MIDI-interface. Although WinUAE supports MIDI, it turned out to miss some data from my MIDI-keyboard. It missed "key up", so notes got stuck.
The only solution for me was to get an Amiga 1200 with harddrive, ethernet, VGA-adapter, MIDI-interface, and turbocard (68030@50). This solution has no problems with missing data. I'm using my SVGA-screen, so the whole setup does not take much space.
