It is it!
I am back on Linux so i was looking for good free synth. Tunefish is one of them, maybe the best one. It works on windows, mac and linux.
And what is great, it was tested with Renoise and it also look like it. So I use it for nearly every sound now :-).
It takes little cpu and it has great layout with good possibilities.
Tunefish is indeed great… i haven’t checked up on updates since i had installed 3.x back three years ago.
It looks so renoish to me that i cant believe it is not native synth.
I like this synth a lot. And you’re right, esthetically it is very pleasing.
Tunefish and TAL NoizeMaker are great free Linux synths
