Studioware - Slackware 14.2 and MIDI keyboard.

Post by globetrotterdk »

I have decided to take my confusion to a higher level and have installed the Studioware audio bits on top of a clean, full, Slackware 14.2 install. The Slackware install is on a Dell Vostro laptop. After a night long compiling, everything is installed and I am trying to get my Novation Launchkey Mini to work with Qsynth, following these instructions. Unfortunately, I am unable to get a sound yet. Fluidsynth is installed:

Code: Select all

# sepkg --search fluidsynth
[Installed]	audio/synthesizers/fluidsynth-1.1.6
but as Studioware uses a different package builder, I am unsure as to where Fluidsynth is located so that I can include the path in Qsynth. I assume that this is going to take more than just setting the path in Qsynth, as I have noticed that Qsynth doesn't appear in the PulseAudio volume control, so here is some various useful output, according to the Arch Wiki:

Code: Select all

$ lsusb

Anyone have any ideas?

Well, I can partially answer this myself:

Code: Select all

$ whereis fluidsynth
fluidsynth: /usr/bin/fluidsynth /usr/include/fluidsynth /usr/include/fluidsynth.h /usr/man/man1/fluidsynth.1.gz
Unfortunately, I had already searched for a soundfont in /usr/bin, and I haven't found any in /usr/include either.
-----
OK, it looks like it gets installed in /usr/share/sounds/sf2/ I used sbopkg to get a soundfont installed. Weird that installing the full Soundware audio section doesn't give you a soundfont...
----
I ran the following and it seems to work as per the instructions:

Code: Select all

$ aconnect 20 128
Unfortunately, the sound is extremely low and nothing appears in PulseAudio volume control, except the speakers. Turning them up to 153% barely gives a usable sound output.
