It has been a while since I have tried to use qjackctl, but I still
run into the same problem.
I open and then start qjackctl, then I open qsampler and load a .gig
file. In connection in qjackctl I connect "32:Audigy MPU-401 #2" in
readable clients to "LinuxSampler" in writable clients. Then I press
some keys on my midi keyboard and QSampler does not pick it up. If I
connect "Vkeybd" to "LinuxSampler" and press the keys Vkeybd using my
mouse, QSampler works??? Many Thanks.

Trying to think through this in my currently befuddled state - so you're
not getting MIDI coming in although you can see the MIDI device?
Is the MIDI interface connected through USB? If so, make sure that you
are not hooking it in via a USB hub. I learned that the hard way.

Hmmm, my USB MIDI interface works fine through my USB hub. Only devices
I've had problems connecting through a USB hub were external hard drives
that drew more power than the hub was able to provide.

There are MIDI hubs and
there are MIDI hubs - the one I've got is a
cheap one.
But the o/p replied to me (but not the list) saying that his MIDI
interface wasn't a USB one anyway.

Then that's a different problem.

Hi Preston,
Use a tool that allows for byte-wise display of incoming MIDI data, such as
kmidimon.
Connect that tool to Your Audigy MPU port and hit some keys on Your keyboard.
Now You can see if there is MIDI data showing up at all.
My suspicion: The MIDI keyboard sends NOTE ON/OFF data in running state mode,
which means, if there is nothing happening apart from sending NOTE ON/OFF
commands it leaves out the first byte (the status byte that actually contains
the NOTE ON command) to save data. The MIDI data stream now consists of
groups of two MIDI bytes only that in turns contain the note value and the
volume value. NOTE OFF messages are note value + volume 0.
You would have to "interrupt" the NOTE ON message data stream by triggering a
different MIDI command, such as PORTAMENTO, foot switch etc. or reset the
MIDI keyboard alltogether so that it will send one initiating MIDI ON status
byte. This could then be received by the audigy and transmitted to Qsampler
and the MIDI data stream would be "complete" again.
I have got this issue all the time when using my MIDIfied electric organ.
Regards,
Crypto.

Thank you Crypto. I will try what you said about using kmidimon and
then get back with you. Thanks again. I hope I didn't send this to
your private email. It seems that when I hit reply in Gmail it sends
it to people's private address?
