Music Install Notes

So the following is a bit different than my usual blog. This more of series of notes from me getting a linux audio computer setup. Since I was installing as I went some directions may be countermanded in further parts of the notes.

low latency kernel

sudo apt install linux-lowlatency
sudo apt install jackd jack-tools qjackctl fftw3 pulseaudio-module-jack  

dbus-python Add some limits for JACK by editing the limits.conf


# caps the real time priority to 99 
@audio   -  rtprio     99
# gives it unlimited memory locking
@audio   -  memlock    unlimited
# sets the allowance for running with modified scheduling priority
@audio   -  nice      -19

Add yourself to the audio group

sudo usermod -a -G audio yourusernamehere

edit the /etc/pulse/

load-module module-jack-sink
load-module module-jack-source

Time to retry

sudo apt-get remove --purge alsa-base pulseaudio
sudo apt-get install alsa-base pulseaudio

Fire up the backend with this will change with your hardware

jackd -R -P4 -dalsa -r44100 -p512 -n4 -D -Chw:0 -Phw:1

So the problem was I was trying to use the hardware 0 instead of hardware 1


Time to add Ardour, it is a DAW Digital Audio Workstation

sudo apt install ardour

Then Audacity ", open source, cross-platform audio software for multi-track recording and editing."

sudo apt install audacity

Why not a drum machine Hydrogen

sudo apt install hydrogen hydrogen-drumkits hydrogen-drumkits-effects 

qjackctl doesn't look as cool as it could so why not Gladish GUI ladish

sudo apt install gladish

Got a guitar? Soft effects Rakarrack

sudo apt install rakarrack

Comfortable with reading? Like the shell? No install would be complete without:

sudo apt install sox ffmeg

All done? Not quite yet you need some MIDI

You need something to make the MIDI data turn into audio:

qsynth front end for FluidSynth

sudo apt install qsynth

Need to test out your new qsynth then try jack-keyboard:

sudo apt install jack-keyboard

Time to connect the MIDI to ALSA.

sudo apt install a2jmidid

Don't forget to launch it.

No sound? Whelp you forgot to install a soundfont.

You can search the interwebs for ones.

After you get that working don't forget you can run it into the same pedal board.

Looks like you forgot everyone's favorite media player VLC not not that one CMUS

Get them both:

sudo apt install cmus vlc
