Summary:                    Midi in still does not work for Hoontech/STAudio
DSP2000 C-Port
Description: 
As reported before in bug 000055 that is now marked resolved.
It has not been resolved.
The problem seems to be related to hardware specific registers on the card
that need to be set.

I will be happy to spend a couple of days trying different flags/bits with
the initialisation code, if somebody gives me an idea of where to start.

I can't speak for the DSP24 card, but I have a mkII version and once I
traced out the logic on the board. I recall that INSEL and DAREAR signal
went no where. They clock-in on a latch, but those outputs of the latch
are not connected to anything. Also, I found that the MUTE signal was
inversed, so I have to patch hoontech.c to MUTE my inputs to turn them on
(for my ADCIII box).

To get MIDI_IN to work on my ADCIII (not sure if this works on c-port), I
need the following part of my default hoontech patch:

-   for (box = 0; box < 4; box++) {
+   for (box = 1; box < 2; box++) {

I'm using midi in on a box addressed as box 1. This patch is obviously not
addressing the root issue, but it works for me. Maybe it gives clue to
someone who knows the code better. It seems like there is some global
signal that is clearing the settings so if I do not limit this loop to the
my box, it gets cleared again when addressing the next.

My hoontech patch:

I can confirm this problem on a recently aquired DSP2000.  The change
suggested by Perex disabled the audio and didn't seem to help midi in.

The change mentioned by sbahling also didn't help.

For now I have to remove this card and return to my now fully functioning
DMX6fire as spare time is needed to campaign against the closure of our
local school!  However I will return to it soon.
