Multimedia :: Sequencer

Sorry i've posted stuff all over the forums about Muse and Fluidsynth. I didn't realise at the time it would encompass so many things!

I'll stick to what I've found out so far trying to get Muse and Fluidsynth working. I'm nearly there but also nearly ready to give up!

Muse does seem to hang when playing around with Audio settings. I have to keep killing it. I added a fluidsynth instance within Muse which seemed ok but when I tried to remove it Muse hangs. Also Muse can hang when you are playing music - it just keeps playing music and when you try to stop it it wont stop.
After a while of killing Muse/restarting the OS seemed to get a bit clogged up ( or Alsa is I'm not sure) so I have to do a reboot.

I think it's ok if you have a Soundblaster, but I'm struggling with USB midi. I will persevere, but maybe it's better to admit defeat and use a Music Distro....it's been challenging trying to get it all working. If anyone else has any luck or is interested in giving it a go please post here...I am still interested in trying to crack this nut.
What I will say is that Muse doesn't seem to present any trouble when Alsa isn't on..it's just when it plays through Alsa things just keep hanging or you need to keep rebooting if something goes wrong. MMMMM.....

Remember how easy all this was with an Atari ST?

I did some playing about with alsa and usb and found that, once I loaded snd-usb-audio, alsa recognised a usb headset without me doing anything in particular:

Code Sample

# modprobe snd-usb-audio
# cat /proc/asound/cards
0 [AudioPCI ]: ENS1370 - Ensoniq AudioPCI
Ensoniq AudioPCI ENS1370 at 0xbc40, irq 17
1 [U0x46d0x8c5 ]: USB-Audio - USB Device 0x46d:0x8c5
USB Device 0x46d:0x8c5 at usb-00:07.2-1.1
2 [headset ]: USB-Audio - Plantronics headset
Plantronics Plantronics headset at usb-00:07.2-1.2

Where the 0 = hw:0,0 and 1 = hw:1,0 etc and AudioPCI, headset, etc are the alsa device names.

Do you get something like this when your usb midi device is connected and snd-usb-audio is loaded?

Note, to test things you can use xmms:

right-click on the player and chose options/preferences
choose the alsa output plug-in
click on configure/user defined
enter "hw:headset" or "hw:2,0" [in my case]
click OK, then try to play something

I didn't see "0 = hw:0,0" anywhere in the code sample. Am I going blind, or is it somewhere else?

EDIT: Juanito, have you ever been able to get linux to both monitor and record simultaneusly? For some reason, programs like Audacity have this capability only in the windows versions. Thus, there is no way to record streaming media (i.e., the recording functions are knocked out whenever a streaming media connection is running).

I'll try that again Juanito. I can see my midi interface in asound/cards but I'm not sure what to select in the dev folder - midi00, midi01 - there's loads of dev devices! I don't own a usb audio/midi interface - it's only midi...buy my Creative labs card is showing in alsa as device 0....I'll try to play some sound again through it and report back. There's something a bit flaky about Muse and Alsa ...maybe...I'm still playing around. All I know is that I'm having to Kill Muse every now and then....when you switch it off from Alsa it plays fine....

I remember using Jack control panel in another distro...you could switch off / on Alsa or the soundsystem if there was a problem but I'm not sure how to do this in DSL using command lines.

It's a shame 'cos I've almost got this going....it would be such a nice little setup if it would work.
I'll report back after some more experimenting.

Yes Jpeters, I owned an St and Falcon...I regret not having them at times as Cubase was very simple and midi incredibly stable. I will be dammed if I don't get this all working in DSL! It will be great if it does...usb stick in any pc....on the move....
