Chapter 10. Soft Synths

Strictly speaking, soft synths are not a part of Qtractor. However, it is common to use soft synths within Qtractor. Acquiring free software synthesizers online is a simple matter of locating them online at sourceforge.net, ccrma.stanford.edu, your distribution's repository, or the project's homepages directly.

Software synths for GNU Linux come in a few varieties:

Independent synth applications that launch separately from Qtractor but that plug into JACK so that the synths can be used as sound sources within Qtractor. One such example is Qsynth, written by the same programmer as QJackCtl and Qtractor.
DSSI Plugins which are launched and controlled entirely from within Qtractor.
LV2 Plugins which are launched and controlled entirely from within Qtractor.
VST Plugins; the format from Steinberg does in fact support Linux technically but the number of Linux-native VST synths are few.
