RE: MIDI getting killed by Jack?

["Mark Knecht" <mknecht@controlnet.com>]

Hi. Does anyone else experience very slow responses from Alsa-Devel? I sent
this email this morning at 9:16AM this morning and it just arrived back here
and at my home account at 1:30PM. Most other reflectors I'm on normally have
round trip times of just a minute or two. Alsa-devel is always so slow,
usually taking hours.

At lunch today I rewired my MIDI input from the keyboard controller to use
the MidiSport input instead of the HDSP 9652 input. In this configuration,
with only about 15 minutes of testing, I had no problems. I will do more
testing this evening, but possibly this data says it's an HDSP 9652 MIDI
problem, or the HDSP 9652 MIDI combined with Jack-type audio, and not
specifically 'Alsa MIDI'.

With this set of connections:

aconnect 80:0 64:0
aconnect 80:0 64:32
aconnect 80:0 80:0
aconnect 80:0 80:1
aconnect 80:1 64:0
aconnect 80:1 64:32
aconnect 80:1 80:0
aconnect 80:1 80:1
aconnect 80:1 130:0

I had no immediate problems driving zynaddsubfx on 130:0. (I think it was
130:0)

Cheers,
Mark
