Angst

[Permalink]     blog music

I had planned to spend this evening playing games; something I really enjoy doing but rarely set aside any time for. However, while we were eating dinner, I put some music on and it got me in the mood for playing some guitar. Over the course of dinner and playing with my son afterwards, that developed into wanting to write and record some music. I used to write electronic nonsense sometimes but this evening, I fancied trying my hand at some metal.

The first 90 minutes was - as almost every time I get the rare combination of an urge to do something musical and time to do it in - spent trying to remember how my setup worked, which bits of software I needed to install, and how to get the right combination of inputs and outputs I want. I eventually got it sussed and decided I'd better write it down for my own future reference.

Hardware

  1. Plug the USB audio interface from the V-Amp3 into the laptop.
  2. Plug external audio sources into the audio interface's input. (e.g. the V-Amp or a synth).
  3. Plug some headphones into the headphone socket of the audio interface.
  4. Switch on the audio interface's monitoring mode ;) (this kept me going for a little while; it's a small switch)

Software

  1. The following packages need to be installed at a minimum:

    • qjackctl
    • qsynth
    • soundfont-fluidsynth
    • vkeybd
    • ardour
    • hydrogen
  2. Use pavucontrol or similar to disable the normal audio system and just use the USB audio interface.

  3. Qjackctl needs the following snippets in its config for when jack comes up and goes down, respectively:

    • pacmd suspend true

      This halts pulseaudio so that jack can take over

    • pacmd suspend false

      This starts puseaudio back up again

  4. Use the connection tool in Jack to hook hydrogen's and qsynth's outputs to ardour's input. Use the ALSA tab to connect vkeybd to qsynth.

  5. When starting Ardour and Hydrogen, make sure they're both configured to use Jack for MIDI. Switch Ardour's clock from Internal to JACK.

The big picture

For posterity, here's this evening's output.
