Tips desperately needed!! Midi controls...

[barbarbaron]

Hello

I've been using linuxsampler for a time now but I generally used it for popular music arrangements till now. And now I have an orchestral job in front of me and I have to master a few key concepts so here it goes:

1. How can I control the volume of an individual channel by means of midi automation? (from a keyboards modulation wheel or from rosegarden's automation tracks)
2. Is it possible to have more than two Jack channels in linuxsampler outputs? How?
3. Can someone explain me the midi maps and how to use them? Are they useful for my project?

My versions: linuxsampler 1.0, fantasia 0.9, libgig 3.3

Thanks to everyone who will answer these questions!

1. How can I control the volume of an individual channel by means of midi automation? (from a keyboards modulation wheel or from rosegarden's automation tracks)

You can send a normal MIDI CC7 to control the volume of the individual channels, or you can edit the .gig files with gigedit to define a new MIDI controller for controlling the volume.

2. Is it possible to have more than two Jack channels in linuxsampler outputs? How?

Yes, of course that's possible. Just access the device management panel (either of qsampler or Fantasia), select the JACK audio device and increase the output channels with the respective spinbox.

3. Can someone explain me the midi maps and how to use them? Are they useful for my project?

MIDI instrument maps can be used to switch to arbitrary instruments (including desired volume adjustment for example!) when receiving arbitrary bank select + program change MIDI message pairs. The details are actually a more complex topic. I'm not sure if somebody already wrote a Howto or something, but you can read the respective section in the LSCP specs to get an idea how the MIDI instrument map mechanism works:

Also take a look at MIDI Instruments
