MIDI BUFFER

MIDI BUFFER

2003-03-12 by riccardo_natoli

Hello Everyone,
I have been a member of this group for quite a while and have learned 
a tone of valuable information from this group. So Firstly I would 
just like to say thank you.

Secondly, I am having some problems with hooking my system via MIDI. I 
am trying to hook up the DTXpress to a Pro Tools Digi 001. I was able 
to do this and get the Pro tools to record the midi.  After I record a 
sound if I try to change kits on the DTXpress while the MIDI is 
playing back through Pro Tools I get this loop happening (where the 
kits just start rapidly changing) and it comes up with ERROR MIDI 
BUFFER FULL. I have turned off local control from the DTXpress to try 
and avoid this to happen but it still continues. Also resetting the 
system does not help I have to physically disconnect the MIDI cables 
for the system to stabilize.

I have already looked over the group's messages but there is no 
specific answer to this problem. 

If anyone has had a similar problem and could let me know step-by-step 
directions of hooking up midi to an external sequence or reasons why 
this MIDI BUFFER FULL could be happening I would be most appreciative. 

Cya,
Riccardo

I'll take a stab at this one... :)

Could be this is happening:

You have the MIDI in and MIDI out from the DTX module going to your
sequencer. When you begin to playback the sequence, the sequencer is in
MIDI-Through mode. When you hit the "change drumkit" selection from the
front panel of the DTX module, it goes out the MIDI out port, is received
by the sequencer, that then "forwards" it to the MIDI in of the DTX
module!

This would be the "loop" that would cause the sequencer to continue to
run up the drum kits till it looped around. Every "up" command received
by the DTX in turn goes out *again* adding to the storm of instructions
eventually causing the MIDI buffer to overflow. To see if this is the
case, try removing the MIDI-Out cable from the DTX module and *them* use
the kit up/down and see if the same result occurs. If this solves the
problem, then go into your sequencer and turn off MIDI-Through. Hope this
makes sense...  :)

Hey Vern,
		Just wanted to say thankyou for your response. This sounds 
very plausible to me. I will try what you have suggested tonight and 
let everyone know tomorrow if this solves the problem. This is such a 
good users group. Keep up he work guys.

Cya,
Riccardo

Re: MIDI BUFFER

2003-03-13 by riccardo_natoli

Hello,
Just to make this thread complete I thought I would post what happened. 
I tried what Vern suggested (see earlier post) and was still getting 
the same problem. I then tries turning off midi thru on both the 
sequencer and the module alternatively. This did not help at all.

But what I found was that as I changed drum kits while recording the 
module was going crazy because of this loop, so i figured there must be 
a way of not sending this information to the sequencer (i.e. record the 
change of drum kit). I looked in protools and sure enough there is a 
choice not to send this function through and it now all appears to work 
fine. I can record MIDI information and while recording change drum kit 
BUT not record that I have changed drum kit. I LIKE MIDI. (just in case 
you are a pro tools user the choice was to deselect send program 
information).

Once again it is the users fault..... me bad.... thanks for everyones 
help.

Cya,
Riccardo
