Hi... anybody out there testing latency on an ACPI patched
kernel? I have two kernels I'm testing:
2.4.19-x:
2.4.19
2.4.20-pre4
low latency for 2.4.19 (w/a couple of tweaks to patch pre4)
acpi-20020815 for 2.4.20-pre4
2.4.18-x:
2.4.18
low latency for 2.4.18-pre10
acpi-20020726 for
I have a Hammerfall Lite on one of my Linux machines, with external
DACs in the speakers. I regret this decision almost every day. It
took MONTHS to get an alsa driver which occasionally worked; it would
run out of memory, refuse to load, etc and the alsa mailing list was
close to useless. I ha

One comment, remember that effects instruments can't have
their state updated at the k-rate via labelled control
statements, because there is no label on the effects
instr! Instead, for maximum portability, what you want
to do is to have a ksig

You want to use an interpolated delay line structure to do
adjustable delays, you create the delay line in the ipass,
make it large enough to cover the reasonable range of delays,
and then pick the tap on the delay line that matches the
current

Howdy, all.
I'm writing a softsynth/toy that uses sfront (via a custom control
driver) to produce trendy, 303-inspired sounds. I realize that this
isn't that interesting a project (how many 303 toys does the world
need?), but I'm using it as a proof-of-concept/stepping stone to a
cooler GUI-cont
Is it possible to lock the ALSA sequencer to audio clock? Most controllers like Envy24
have a register called "Playback DMA Current/Base Count Register" (= where the 'play
position' inside the DMA buffer is currently). Can ALSA sequencer also send MIDI clock
based on this counter to MIDI out? W
