Well, I have 3 way for obtain by Gambas Midi data: (explained in (italian language): http://www.gambas-it.org/wiki/index.php/Gestione_del_MIDI_con_ALSA )
1) receiving data FROM ALSA by an ALSA function and using a loop with "Timer" function (but I would not to use Timer because its inexorable latency); 2) via: OPEN "/dev/snd/midiC2D0" for Watch ...watching file-device created there, when I connect an external Midi-Keyboard. But this is a "extra ALSA" metod ! Because, so, I intercept Midi-data from virtual port of my external Midi-keyboard, not fron ALSA functions.... instead I will to receive FROM ALSA; 3) receiving FROM ALSA, by using an modified program in C. This program in C receives the data and then it sends them to stdout; with gambas-program I read those data. (look example code at: http://www.gambas-it.org/wiki/index.php/Alsa_e_Gambas:_Ricezione_con_un_programma_esterno_di_supporto ) Bye Paolo --- Dom 18/9/11, Ron <[email protected]> ha scritto: > Da: Ron <[email protected]> > Oggetto: Re: [Gambas-user] Release of Gambas 3 RC3.
