Software Synth Library for Java [closed]

Answer 1

Have you checked out JFugue? It's an "open-source Java API for programming music without the complexities of MIDI".

Additional information: Found a couple of other resources referenced in the JFugue documentation (pdf):

• Audio Synthesis Engine Project: open source version of Java’s MIDI synthesizer

• Gervill: open source software synthesizer created as a proposal for the Audio Synthesis Engine Project
