Modularity ;) But of course we may change that, given reasonable
behavior wrt network finish.

No, but you might as well just use 1e30 then :) Would it be reasonable
then to change the repeat time to default to 0.0 (i.e. endless)?

No, the global settings dialog is what you are looking for. Just
change the "Size hint for audio buffers [samples]" to 128 (or 64)
and you should get reasonable latency (read: ~5ms) - dependent
on the intelligence and internal buffering of the plugins, of course.
At least that is the latency I get with my ISA SB AWE / via onboard
sound (yepp, not full-duplex, but sampling from sb, playback on via,

Hope so. Whats these "nasty" things? We might want to fix those
