mysteries?
Does it not play the file, or are you simply not getting any sound output?
I test the midi
$ timidity /a-train.mid
Sounds great!
OK, so your basic sound set up works, Good.
MYSTERY #1: How does timidity know what port to use
and what
instruments to
use? I never told it what bank, etc.
I guess you were lucky ;-)
MYSTERY #4: What is the significance is General MIDI
Synth #10[D] ? I
alwasy
see teh [D] at slot 10. What does [D] mean?
Probably that It's a drum track rather than a synth track.
When I play, I hear nothing!
The only thing I see that has changed is that rosegardensequencer has
started jack...
/usr/bin/jackd -T -d alsa -d hw:0 -p 2048
which is bad because jack, so far, has only succeeded in preventing any
sound to work in any manner. I just want rosegarden to work with midi as I
have given uip on jack after about 70 hours of frustration with jack. I'll
get back to jack when I have a few months of free time.
Ah, AFAIK, if you want to get MIDI driven sound out of Rosegarden4, you have
to use a softsynth via Jackd. Use Qjackctl to start Jackd, then start up the
softsynth you want to use and then Rosegarden. It won't take months to
figure, I know it can seem daunting at first, but you really are going to
want it working from the sounds of things.
However, when I quit rosegarden, I hear a single note
play!!
Are you sure that's not just a system beep?
Appearantly, my timidity port has been fubared by
rosegarden (or something)
No, I doubt it. If you're using ALSA, only one application can have access to
any device. It's just in use - the port still works & is still recognisable I
think you'll find :-)
Other mysteries...
MYSTERY: Port 64 is 'Intel 82801DB-ICH4 MIDI - Rawmidi 0' [type=kernel]
How do I load sounds into this external midi? When I run rosegarden it
shows that there are banks of instruments available but no sound comes out
when I play "aplaymidi -p 64:0 /Blew.mid"
You can't, it's not a SoundBlaster. You need to use something like fluidsynth.
MYSTERY: Some midifiles, when loaded into rosegarden
have "Imported MIDI"
in channel 1, but nothing there, and things like 'Rhythm' assigned to MIDI
external device #10[D]" (there's that 10[D] again). n In this example, the
file that have this information do not play with aplaymidi
This is normal no? - channel 1 contains the original MIDI info or something
like that. It's normal to assign the Rhythm track to #10, It's a handy
convention, why it should be an external device, I don't know, I can't see
from here :-)
HTH a bit
