I got everything installed on Arch Linux. Quite a lot of compiling time but it was straightforward.
I like the SynthDef as module concept. There’s quite a lot of impressive work in there.
It wasn’t obvious how to do a hello world style VCO => VCF => VCA setup, but I did figure out how to make sound. I couldn’t figure out how to connect control rate modules to anything which had audible results.
The GUI has a kind of buffet style and the meaning of some control widgets wasn’t immediately obvious.
The help system exists, though it was a hard read to follow for an afternoon project.
I’ll give it some more time but I plan to continue building my own controller system, perhaps with the SynthDefs included in TX.
