I did answer to your mail before, if this isn't precise enough, well, I could go deeper to the stuff. What exactly is needed for a 'Linux community correct question'? Since the 80ies I've forgotten a lot, but this isn't an issue, I still have all those folders (not files, real one for paper) at hand. I did program + solder, I guess for MIDI on Linux the coders have a lot of knowledge regarding to program by theory, but they miss to optimice it to the oldish hardware (no soldering anymore). Not the MIDI hardware or the technical specifications are bad. Don't believe me, just compare a sequencer from the 80ies with a Linux one. Truth seems to be a problem for Linux rt :(. _______________________________________________ 64studio-users mailing list [email protected] http://lists.64studio.com/mailman/listinfo/64studio-users
