NULL-Mode is a little more complicated:
In INPUT MONITOR Mode us428control knows all to handle it.
In not INPUT MONITOR Mode us428control has to know from i. e. Ardour the Mixer

We can also vary the exact USB frame time.
With UHCI 1.1 USB Hosts there is the SOF Register.

Using this SOF-Register, we can set the actual USB Frame Rate from

the patched usb-midi driver is used by the us428

we can avoid having different alsa-devices for the

hey,
on http://hal9000.drehmoment.org/tascam/ you can download a patch against
cvs of august 14.
it contains:
- snd-usb-us428
downloads firmware to endpoint 2.
creates 2 midi devices through the patched snd-usb-midi
and 2 input + 1 output pcm devices.
- snd-usb-midi with exports

not generally. i.e. the pinnacle/fiji way is to map a piece of memory into
the pc's memory space.
thus an application using alsa-mmap can write (or

(apply the diff to a cvs-download and copy the other

It does the coldboot (DeviceID 0x8000) firmware
download after the us428 is switched on.
you can use the a.out together with libusp

Hi Takashi,
here is a newer version.

thanks, we got finally the support for this old
card.
i'd like to put this stuff into cvs,
hi,
new in this is pcm record and midiin.
latency (latency -m32 -M32 -b -r 48000, patched to
allow 3 periods) runs with down to 32 frames.
amSynth runs well with it on an 400PII.
mmap driver for amSynth available from me.
not needed, but gives you more voics with the
fiji/pinnacle.
works:
hi,
new in this is onboard memory maped playback at up to 1387 cycles/s ;-)
on a 400PII with no xruns, if it runs with realtime scheduling with no other
hungry tasks.
it is still err.. a little unstable: for instance crashes while accessing
some /proc/asound files.
works:
PCM:Stereo
somebody working on drivers for this card?

hallo,
this one lets the volume reach maximum on both
channels also by using the extra volume-control-knobs
found on some laptops.
the diff was run against the cvs - version of today.
