On win95, one can play around with the system timer and generate
timer events to a VxD with <3ms latency.
Combine this with the new generation of scatter/gather DMA PCI cards
(Turtle Beach (www.tbeach.com) will start selling its Montego card next
week that seems quite nice: 18bit AD/DA, 16 hardware digital mixers
with independant sample rates, 32 voice HW wavetable synthesis for $129),
and it seems like it might be possible to write some software that
features of the software mixers/Midi sequencers with the looping features
hardware loopers. I don't know, however, if this can be done through a
interface such as DirectSound or whether acheiving the low latencies
this type of application requires sound card specific knowledge.
This is probably fairly off topic for this list.
I have, however, been thinking of writing some SW of this nature
and would be interested in exchanging ideas with anyone that has
played around in this space.
