I asked because I was stick with the alsa rawmidi librarie. It is a similar project,mindingsolo http://home.gna.org/midingsolo/index.html I took a look on its source code. It use a music library that is a part of the program. I believe at I can use it. It implement almost all the functions I will use, and as it use only the alsa sequencer, it will be less work to me to add a pitch function in it, as to write all from the scratch. I will contact the mindingsolo gui later. For now I must focus on a few small programs in order to learn how to use alsa and jack, and how to adapt the algorithm. Ciao, Dominique Yes. I believe at my algorithm can work with jack and alsa because the clock of a modern pc is much faster as the 20MHz of my dsp board. As the linux threads are very well done, I believe at the processing time will be proportional to the audio sampling frequency and at it will work.
