Thanks Mac,

Ketron works fine with Reaper on the same machine with the same MIDI files. I should have mentioned this previously.

It really appears that this problem started after I installed the latest RB 2014 patch.

The problem is that the wrong patches are used when a new MIDI (inside a SEQ file) is loaded. I'm going to try the actual MIDI files and see if the problem persists or if it is only when the MIDI is in a SEQ file.

I have two files that clearly illustrate the problem and can repeat the problem. Neither file has any SysEx's or strange CC's in them. But all of the MIDIs that I try to play have the problem, and I have to click 2 times on Panic before I play them or some tracks are using the wrong Patch.

If I click on Panic 2 or 3 times before starting the MIDI it plays perfectly. If I stop and restart the MIDI it ususally plays properly after the 2nd or 3rd restart.

When I load a new MIDI the drum track always seems to be fine which is expected since channel 10 is dedicated to drums. But the other tracks may be using patches from the previous MIDI, or are just not properly registering the patch value that is sent by RB.

Some MIDIs you don't notice a dramatic difference, just that they don't sound "right". But some of them where radically different instrument patches are used are very noticable.

In one case the track that should have been playing rock organ was playing a Piano. And I could NOT change the patch and have the instrument change until I had stopped playing and clicked on Panic a couple of times. Then the patch change applied and all was well until the next MIDI was loaded.

I've been talking with PG and have sent them two files that illustrate what I'm seeing, but I believe that this is something in my configuration that is causing this to happen.

I've pretty much confirmed that it is something between RB 2014 (patched) and the Ketron via the USB to MIDI interface.

Since the Ketron is working fine from Reaper using the same exact USB to MIDI interface on the same machine I can rule out the USB to MIDI interface and the Ketron as being the source of the problem.

So I guess I'll have to see what PG comes back with for suggestions. If all else fails I'll unregister 2014, uninstall it, and do a completely fresh install. Test operation and then install the update patch again and retest.

If it still fails on this machine then I guess I'll have to roll back to 2013 and forget 2014 until PG fixes it.
