I managed to write my first Haskell program with a GUI! It shows a window of sliders and when you move a slider it sends an according MIDI controller message via ALSA.
http://code.haskell.org/~thielema/alsa-gui/ Now I like to provide the reverse direction: If my program receives a MIDI controller event via ALSA, then it shall update the slider position. I can do this by using WX's timer events and check for incoming ALSA events in regular intervals. Is there also a way to wait for ALSA events as they come in, without a busy wait? ------------------------------------------------------------------------------ Benefiting from Server Virtualization: Beyond Initial Workload Consolidation -- Increasing the use of server virtualization is a top priority.Virtualization can reduce costs, simplify management, and improve application availability and disaster protection.
