How to use the virtual keyboard in fantasia?

Hi all,
I'm new to linuxsampler and fantasia. I have succesfully compiled everything and I'm able to load the maestro_concert_grand_v2.gig file and connect things up to either alsa or jack.
However, I can't figure out why the virtual keyboard in fantasia does not produce sound; I also noticed that in a recent screenshot of fantasia 0.8cvsX the virtual keyboard had various colors signifying ranges and/or activeness, whereas my virtual keyboard stays gray-ish. I can click on a key and it will highlight green.
I suspect the virtual keyboard is an actual midi device and should be connected, but how and what channel/port would it be at?
Help! I am so close
Kind regards.
PS: I'm runing: gigedit-0.1.1, JSampler-0.8a-cvs5, libgig-3.2.1, linuxsampler-0.5.1

You need to use the CVS version of LinuxSampler. The backend functionality for the virtual keyboard is brand new and 0.5.1 is pretty old by now. The virtual keyboard communicates with LinuxSampler over LSCP.

Ah thanks, that's a handy tip. I will rebuild using cvs versions of libgig, linuxsampler, jlscp and jsampler. I'll post an update so people know how it went.

Yes! works like a charm. I did a checkout of the following modules:
Code: Select all
# cvs -z3 -d:pserver:anonymous@cvs.linuxsampler.org:/var/cvs/linuxsampler co libgig
# cvs -z3 -d:pserver:anonymous@cvs.linuxsampler.org:/var/cvs/linuxsampler co linuxsampler
# cvs -z3 -d:pserver:anonymous@cvs.linuxsampler.org:/var/cvs/linuxsampler co gigedit
# cvs -z3 -d:pserver:anonymous@cvs.linuxsampler.org:/var/cvs/linuxsampler co jlscp
# cvs -z3 -d:pserver:anonymous@cvs.linuxsampler.org:/var/cvs/linuxsampler co jsampler
I then did the auto-tools dance within every subdir (for stuff that did not get copied or setup correctly I simply copied the relevant scripts from the stable version's tar.gz):
Code: Select all
# aclocal
# autoheader
# autoconf
# automake --add-missing
I then continued to ./configure; make; make install everything, in my case under /opt/linuxsampler. After succesfully building and installing the softwares, I made a little script to start fantasia with linuxsampler and a default.lscp script pre-loaded:
fantasia.sh:
Code: Select all
#!/bin/sh
export PATH=/opt/linuxsampler/bin:$PATH
/opt/linuxsampler/bin/linuxsampler &
sleep 2
cat /opt/linuxsampler/bin/default.lscp | socat - TCP4:localhost:8888
java -jar /opt/linuxsampler/lib/java/Fantasia-0.8a.jar
pkill linuxsampler
default.lscp:
Code: Select all
SET ECHO 1
CREATE AUDIO_OUTPUT_DEVICE JACK
SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 JACK_BINDINGS='alsa_pcm:playback_1'
SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 1 JACK_BINDINGS='alsa_pcm:playback_2'
CREATE MIDI_INPUT_DEVICE ALSA
#SET MIDI_INPUT_PORT_PARAMETER 0 0 ALSA_SEQ_BINDINGS='72:0'
ADD CHANNEL
LOAD ENGINE gig 0
SET CHANNEL AUDIO_OUTPUT_DEVICE 0 0
SET CHANNEL MIDI_INPUT_DEVICE 0 0
LOAD INSTRUMENT '/home/rubin/Music/LinuxSampler/maestro_concert_grand_v2.gig' 0 0
GET CHANNEL INFO 0
QUIT
When I want to fool around with linuxsampler, I simply start my jack setup with qjackctl, after that i fire up fantasia.sh and I can play music right away. Happiness!
Thanks for the pointers!
Rubin.
