pianobooster for Debian
-----------------------

To hear the sound Piano Booster needs a MIDI sound generator, there are two
different General Midi sound generators available on Linux, 'fluidsynth' and
'timidity'.

To install fluidsynth you must install the following packages: 'fluidsynth',
'fluid-soundfont-gm' and 'fluid-soundfont-gs', using your favourite package
manager.

To start the fluidsynth sound generator copy and paste the following command
line:

fluidsynth /usr/share/sounds/sf2/FluidR3_GM.sf2

Piano Booster FAQ suggests this line instead:

fluidsynth -C 0 -R 0 -r 22050 -c 6 -z 128 -l -a alsa -o audio.alsa.device=plughw:0 -o midi.alsa_seq.id=fs /usr/share/sounds/sf2/FluidR3_GM.sf2 /usr/share/sounds/sf2/FluidR3_GS.sf2

If you have a fast machine, you can leave out the flags '-C 0 -R 0 -r 22050'
which turns off the reverb, chorus and reduce the sample rate.

The flags '-c 6 -z 128' control the latency. Try '-c 5 -z 128' for less
latency but at the risk of audio drop outs.

The flags '-o audio.alsa.device=plughw:0' bypasses the Pulse Audio layer
which might cause a lot of latency delay, but unfortunately these flags
may also bypass the desktop volume controls.

For more information on running fluidsynth with low latency see this page:

https://github.com/FluidSynth/fluidsynth/wiki/LowLatency

On PianoBooster set the Setup/Midi Setup/Midi Output Device: to "FLUID Synth (fs):0"

If you get problems with unsteady playback or the audio cutting out then try
closing all other programs, turning off your wireless network and unplug any
network cable.

If you get an error, make sure to have snd-seq-midi kernel module loaded in your
system (sudo modprobe snd-seq-midi).

You might prefer to use qsynth as GUI interface to fluidsynth for easy setting
of Reverbs, chorus effects, etc.

Hi Miriam,

I updated the license for RtAudio several years back to address your =
concern but neglected to do the same for RtMidi.  The following is what =
I currently use for RtAudio and I propose it should be the same for =
RtMidi.
