Linux Audio and MIDI

Postby Lin » Sun Apr 12, 2015 1:55 pm

I'm not sure, whether I am posting this in the right category. I am making another attempt to get Linux Audio work for me, but I am stuck.

I want to use my System (currently a Thinkpad x230) for
1. Audio Recording, Mixing, Mastering, both portable and in my home-studio.
2. Midi Recording and editing, both in real time and step-by-step, including creating/printing sheet music.
3. as a soundbank for my Roland RD700nx in live scenarios.

With regard to 1. I have been rather happy with an Audio Distro, Ardour, Audacity, and a few other applications and effects. But I have repeatedly failed to get going with regard to 2. and 3. because I cannot get the software to do what I want:

- I am looking for good, and preferably big soundbanks - orchestras, drums, synths, anything. I'd be happy to pay for them, but I have not found much information where to get some that are good and work painlessly on Linux (Ardour, MuseScore). I don't like editing sounds with synths and effects. I would hope to simply have a huge number of sounds to choose from and start writing music.
- I am looking for a Score Editing Software, which lets me, again, simply choose a sound or several, and then let me input the notes. MuseScore 2.0 comes close, but I am having an issue with it, that makes working with it impossible (it seems impossible to play polyphonical while editing mode is turned off).
- I have been trying to use a computer as a soundbank fpr live playing sporadically since 1990. At the time the lag was simply impossible. I find it funny that 25 years later I am still having the same issue. Ok, the file sizes have grown proportionally, but when I load even a half-way decent sample/soundfont into Ardour or Musescore, playing it from my stage piano does produce an audible lag. Is there a more dedicated software for this purpose that solves this issue to a sufficient degree? What software would usually be used to use the PC simply as a soundbank for a MIDI instrument? Or would I have to resort to a good-old midi-expander?

I'd be glad for any help, like the right Google-search-terms..

The first thing I would try to eliminate the lag (a.k.a. latency) is look at your jack settings.

Of the options given I use qjackctl. Epecially try and get the frames/period setting as low as you can with the system still staying stable and not producing xruns.

If it is any encouragement, I do not have expensive gear and I am able to get my system usable, so this is do-able.

Thanks, this helped with the lag.

As for the rest, I am making progress, slowly. So maybe I'll get there one day. At the moment I am waiting for the next version of Musescore, which will have polyphonics fixed.. and next is getting vst instruments to run on wine..

Glad it helped. Once you get your head round what you need you will be able to concentrate on the music :)
