Hi Frank,
Though I guess I understand what you mean, I'd
like to note that
CSound, SuperCollider and Pd are the by far the most widely used [1]
synths on Linux, so one could argue that they are the real
"mainstream" Linux synths. ;)
I should have written 'CSound, Pd, or SuperCollider' (in ASCII
order) of course :-)
Depends on what you call 'a synth' - each of the above can be used
for emulation of (hardware) synths, but they all go much beyond that,
being more full electro-acoustic composition tools.
