Hi Juan.

Therefore I think that the question should go a bit further.. Does anyone have a MIDI IN & OUT setup working in Linux with Kernels 2.2.x or 2.4.x ?

I've no problem with MIDI IN & OUT with kernel 2.2.x ; Soundblaster live I'm using alsa on a mandrake 7.1 (close to red hat)

notice that PD32 is mutch more faster for MIDI IN than PD31

Hi,

about alsa 0.9.0 + midi: I asked once on the alsa-dev list, since i noticed the midi ports were always busy with the newest alsa packages.. nobody did answer until i mentionned it on the lad mailing list. Then a couple of days later some changes were committed on the alsa-cvs fixing my rawmidi problems. The only question is that now, while the midi works everywhere, the api in cvs as slightly changed again (for mmap access i understood) .. but everything should work fine in OSS emulation.

now it works with alsa CVS on my gus pnp ..

Hi, Alfonso, I think you want to use your SB Live! internal synth. I did it last week with my SB AWE64 ISA card. I think it's quite similar, so I have adapted what I've done for your card, but I did not test it with a SB Live card actually. Please tell me if informations below worked for your card.

1. Alsa drivers

I installed 0.5 Alsa driver and PD works fine with the OSS emulation (for me, it's quite buggy with the -alsa flag, but I don't know why)

...

As I said, audio works perfrctly well with the alsa driver. Does alsa configure midi too?

I think Alsa configures midi by default, but you can use: ./configure --with-sequencer=yes --with-oss=yes before you compile the drivers.

2. Testing midi

Please use pmidi, a utility for playing midi with alsa drivers, you can dowload it at: http://download.sourceforge.net/pmidi/pmidi-1.4.1.tar.gz or, if you prefer RPMs : http://download.sourceforge.net/pmidi/pmidi-1.4.1-1.i386.rpm

then, you can use it with -l option, it lists the midi devices. You should obtain: #> pmidi -l Port Client name Port name 64:0 External MIDI 0 MIDI 0-0 65:0 Emu10k1 WaveTable Emu10k1 Port 0 65:1 Emu10k1 WaveTable Emu10k1 Port 1 65:2 Emu10k1 WaveTable Emu10k1 Port 2 65:3 Emu10k1 WaveTable Emu10k1 Port 3

If you don't get this, there is a problem with your alsa drivers setup. May be you need to do: /sbin/insmod snd-synth-emu10k1

3. Playing Midi

So you can play a midi file with this command : pmidi -p 65:0 your_midi_file.mid

The "-p 65:0" means "use Emu10k1 Port 0" found with pmidi -l If you can't hear any sound, please use alsamixer first, or: amixer set Synth 100% If you still can't hear anything, you should load soundfonts in your card

4. Loading Soundfonts

There is no preloaded wave tables in this card, so when you use pmidi and it seems it is doing something but no sounds, it is just playing "blank" sounds. SoundFounts is a trademark of Creative for wave tables in their Live! and AWE32/64 cards. Soundfonts are loaded in a RAM chip on the card, so you can use other soundfonts, or edit them.

To load these "soundfonts" in your card, you will need sfxload utility, from the awefx package. You can find on your Red Hat cd-rom a awesfx RPM, install it. Then you will need a soundfont file, you should find 8mbgmsfx.sf2 on your SBlive driver disk, copy it in /etc/midi/ Then this should load the soundfonts: sfxload -V100 /etc/midi/8mbgmsfx.sf2 And try again: pmidi -p 65:0 your_midi_file.mid you should hear something.

5. Using internal synth with PD

(I tried to understand how work alsa midi devices, but it's still not very clear to me. If you have some details about this, please let me know.)

If you don't use any external midi synth, here is a "absolutely not elegant" way to do it: rm -f /dev/midi ln -s /dev/snd/midiC0D1 /dev/midi Then run PD (without the -alsa flag) Now you should hear something with the "Test audio and midi" patch.

I hope this could have helped you. Nicolas Lhommet

Hi all,

I assume Alfonso is running OSS. OSS's emu-10K1 driver doesn't allow you to "select" on incoming MIDI, so Pd sees no MIDI input. The best solution is probably to download Alsa 0.5.10 (www.alsa-project.org), install it, and compile Pd to use it...

As far as the ESS Maestro chip, I have tried with OSS and ALSA and they only work in MIDI OUT mode using /dev/sequencer which in ALSA is OSS emulation. No duplex communication at all. Also many laptops don't have

When I get to the midi help patch (midi.pd) by clicking help on the menu from a "noteout" object I don't know what values should I put in midiout:
