Open Source

Ok. We already know that Gimp sucks. So today I checked LMMS - an Open Source Fruity Loops clone. It doesn't even support sf2 soundfonts and crashes when you clear all instruments.

Even the ancient Modplug Tracker supported sf2 fonts, but not the open source crap. That is what you get with communism.

As a solution, Linux engineers propose using a collection of raw WAV files, instead of a proper soundfont:

Try the Audio File Processor.
If any of your instrument samples are wav. or ogg. you'll be able to open it, in Audio File Processor. :)
you create a whole sample pack of correct lenght-to-pitch samples, with audacity.

Amazing?!
