My guess it that the problem lies in the sequence, since it only occurs on certain songs. Some files will read differently on different midi playback devices, hardware or software.

How were the sequences created? Do you have a software program that provides a comprehensive analysis of all events. Have all tracks been rechanneled? Since tracks are affected other than those you're tweeking, there may be some channel event crossover. Look over the events list very carefully. Good luck.

They were all altered by my Korg I2. However some were bought. some are midi files over the net. Some are ones I made from scratch. But I have edited all of them.

I have gone into the sequence and see no control changes I'm unfamiliar with. The kicker is that they don't change at at UNLESS I do something on the Solton with the master track and save it. That's when it gets screwy.

justforfun000,

I am assuming these files already reside in your MIDIFILE folder of your HD. Before loading them into the sequencer, please convert [CONVERT (F3) when accessing this files in this folder] - save as another name if you wish to maintain the old one. Now load the converted file into sequencer and proceed as you currently do.

This should help.

Thanks.

Hmmm...this is new to me?? I've seen the "Convert" button but I didn't know what it was for.

By sequencer I hope you don't mean the actual sequencer in the SD1. I haven't gotten that far yet. I am copying the midi files from floppy into the master folder and simply loading them up.

Then I let it play and change the few things on the fly like instrument assignment, volume, reverb etc. Save it back like that which I understand is the master track, and hope that does it.

I understood that the master track is easy because it overrides all other commands. In most cases I change things like volume and reverb in my old keyboard and re-copy it in the Solton if that will solve my problem. Much easier and surer that way (apparently). However, many instruments cannot be called up from my old board by program changes and therefore I need to change the instrument in the solton. If I knew how to change it by a control change in the Korg, I suppose I wouldn't need the master track at all, but I don't.

So is the way I'm doing this not advised? I still can't understand why the volumes would change for no reason.

Not sure if this is any help - but I noticed similar situations on the SD1 and found different sets of midi messages recorded on the master track that I don't know how they got there - but volume changes were part of the problem. I just started deleting random things and sometimes the problem got solved. There seems to be some proprietary anomalies with the SD1 sequencing system that drive one crazy. Track and channel assignment complexities for one.

It sounds to me very much like a Sysex problem. What some people are unaware of is that midi files will play on many different keyboards and modules, but will not play or will do all sorts of unpredictable things on others. This is why I think you get the problem on some files and not others. The problem files may need a GM/GS reset sysex command (which is set automatically at the beginning of the midi file). It's good policy to always do this anyway on all your midi files, especially those off the net.
Hope this helps.

That sounds like a good idea.

I do have Cakewalk - Sonar. I know almost nothing about it except how to play the midi files. Can anyone give me a simple step-by-step way for me to put that Sysex reset command on all my midi's?

I copied this info from Cakewalk's FAQ Site section. If you do a search in Sonar's help menu, it should tell you in more detail, but if you still have problems let me know).

"Load the "Turn GM System On" system exclusive bank (GMSYSTEM.SYX in your Cakewalk directory) in the Sysx View, and set the bank to "Auto Send". This message will re-initialize a General MIDI compatible sound module to a known state".

Ron

Thanks. I'll give it a try
