[Linuxsampler-devel] trials

[Robert J. <rj...@sp...>]

Hi guys,

Back yet from your respective vacations? :-)

I tried to get linuxsampler+qsampler working tonight. So far it is less than 
spectacular.

Compilation worked very well, launching qsampler worked aswell, but I was 
unable to instantiate any channels from qsampler, everytime it complained 
about these things:

21:56:11.257 lscp_set_channel_audio_type: There is no audio output driver 
'Jack'. (errno=0)
21:56:11.261 lscp_set_channel_midi_type: There is no midi input driver 'Alsa'. 
(errno=0)
21:56:11.265 lscp_set_channel_midi_port: There is no MIDI input port with 
index 0. (errno=0)
21:56:11.284 lscp_set_channel_midi_channel: There is no MIDI input port with 
index 0. (errno=0)
21:56:11.302 lscp_load_instrument: No audio output device on channel (errno=0)

The port names are not spelled uppercase which in later tests seems like it 
could be the problem. I rumaged around in the sources for a while but could 
not find where these come from...

I had built linuxsampler from cvs and qsampler from the latest version which 
might account for this discrepancy?

---
Anyway, having failed that I grabbed the specs and tried going from there. And 
got a bit further:

CREATE AUDIO_OUTPUT_DEVICE JACK
CREATE MIDI_INPUT_DEVICE ALSA
ADD CHANNEL
LOAD ENGINE GigEngine 0
SET CHANNEL AUDIO_OUTPUT_DEVICE 0 0
these worked, after this I was going to add a midi device also, but this I was 
unable to do. 
SET CHANNEL MIDI_INPUT_CHANNEL 0 0
returned that the midi port didn't exist
I tried some MIDI_PORT commands also to no avail.

There's something I'm missing, I'm sure... I'd be grateful for some insight.

Also, a minor bug in the interpreter, even if you input a command correctly 
but give it the wrong arguments the interpreter still complains:
Err:0:Unknown command.

Which I really think should be changed to:
Err:x:Bad parameter.
or something similar.

All for tonight, keep up the good work! 

/Robert
