Thanks :) I mentioned it in the post though:<p>&gt; Both Skoar and Alda (which was linked yesterday) are only orchestration languages.<p>I&#x27;m also interested in instrument generation and, while Skoar plugs into SuperCollider, Alda seems to be specifically MIDI output. You could probably hook Alda -&gt; MIDI -&gt; synthesizer though, but you&#x27;d still have to program the synthesizer in a different language, which kind of defeats the purpose.
