Well, I am running Linux Mint (64) and the PB program will work, except for the sound.
I did try to run Fluidsynth, getting a midi output option, though with all my playing around, I could not get any sound output.
I am excited that program runs well just without the sound, which is the sad missing part. I don't know how to properly use Fluidsynth or Timidity. I did try to make a read on them, but I can't get any sound output.
I do inquire to get some help and to make this work. Without the sound, its missing the most critical part.
I did try to read all i could to learn other people problems that may relate. Sadly, I found i still cannot solve this problem.
I am happy to share any information I have in hopes for the guidance that gets it running.
Knowing how to install Fluidsynth or Timidity might be a huge step.
Perhaps there are some other problems I am not aware of?
