Re: trouble sending sysex

2005-09-26 by steve_the_composer

Hope you can get it resolved. BTW do you have an "old-fashioned" 
sound card with a joystick port in your system? If so, perhaps you 
could use it (with a midi/joystick cable which are dirt cheap now.

Sysex and midi were pretty straight forward pre-windows, and while 
Windows makes everything else possible, there is so much overhead 
that G-d knows what's happening to the byte-by-byte midi stream.

Anyhow, it sounds like you need to do some serious diagnosis, 
starting with the simplest possible midi flow and the simplest 
possible tests. (eg, get a setup so you can send one preset to the 
computer and receive one preset from the computer.)

To test sending and receiving you could try midi-ox or even e-
loader's midi monitor. In fact, try it with patterns and e-loader.  
Can you successfully get the names of a bank of patterns?  If so, 
sysex is working. If not, you've got a problem from the get go.  Can 
you download and upload patterns in e-loader? If you can, sysex is 
working. If not, you gotta work on the basics.

In using e-loader, when you scan for midi devices, does the e-mu 
show up (using the midi connection, not the usb host connection]?

Of course, if the windows media player thing will work off the bat, 
or if trying a different interface will work, great!!!

Good luck.

Hmmmm. Just an afterthought--try some different cables.  Every so 
often I've gotten a cable that seems to work at least 99% of the 
time, but is 1% defective for some reason.
