about bars&pipes:

What I've done:

1. Connect USB-MIDI-Interface: Edirol UM-1 - success
(is bound via camdusbmid.class to Poseidon-USB-stack, poseidon.library,
showen in Trident Prefs for Poseidon)

2. Start BarsnPipes - success

3. Set MIDI-connection: connect to cluster "mididriver.out.0" - success
(this is done via camd.library)

4. Send a simple NoteOn-event
BarsnPipes->mididriver.out.0->camdusbmidi.class->UM-1 - failed
(this results in a total crash)

there is something wrong with the driver unfortunatelySad

Hi,

My bad, I didn't check the out going data code assuming it would work but of course it didn't and made AROS to crash.

I upload another version which doesn't crash ( https://hitchhikr...driver.zip ), i also added MidiThru (which forwards messages from a port to another) and MidiSendC (which sends a middle C to a given port) shell commands.

The MidiWatch tool logs the out going port properly so the data is sent but i'm not sure that it reaches the Midi device itself.

Sorry for the inconvenience,
f.

I found out that there are two bugs in camdusbmidi.class.c which prevent from sending several midi messages in the function nParseMidiOut() :

 
 switch(cmd>>4)
 {
 case 0x8:
 case 0x9:
 case 0xa:
 case 0xb:
 case 0xe:
 if(len < 3)
 {
 len = 0;
 break;
 }
 len -= 3;
 *out++ = cmd|chan; <<<< should be: *out++ = (cmd >>4)|chan;
 *out++ = cmd;
 ca->ca_TXReadPos = (ca->ca_TXReadPos+1) & mask;
 *out++ = buf[ca->ca_TXReadPos];
 ca->ca_TXReadPos = (ca->ca_TXReadPos+1) & mask;
 *out++ = buf[ca->ca_TXReadPos];
 ca->ca_TXReadPos = (ca->ca_TXReadPos+1) & mask;
 goodpkt++;
 break;

 case 0xc:
 case 0xd:
 if(len < 2)
 {
 len = 0;
 break;
 }
 len -= 2;
 *out++ = cmd|chan; <<<< should be: *out++ = (cmd >>4)|chan;
 *out++ = cmd;
 ca->ca_TXReadPos = (ca->ca_TXReadPos+1) & mask;
 *out++ = buf[ca->ca_TXReadPos];
 ca->ca_TXReadPos = (ca->ca_TXReadPos+1) & mask;
 *out++ = 0;
 goodpkt++;
 break;


A fixed version is now included within the archive: https://hitchhikr...driver.zip

So to install the whole stuff:

- Copy "mididriver" into devs:midi (and remove any file that may be there before).
- Replace "camdusbmidi.class" from SYS:Classes/USB with the one included in the archive.
- Reboot.

Hopefully the last version of the driver (renamed usbmidi); there were two other bugs in SysEx messages sending.

https://hitchhikr...sbmidi.zip

Same deal:

- Copy "usbmidi" into devs:midi (and remove any file that may be there before).
- Replace "camdusbmidi.class" from SYS:Classes/USB with the one included in the archive.
- Reboot.

I sent a copy of this to Alfred Faust.

.

If I understand well it has to be removed into devs:midi also the file named "mididriver"

Yes, the latest version is here: https://hitchhikr...sbmidi.lha

There was a bug in camd.library i fixed as well.

Mr. Faust confirmed that everything is now working properly.
