Hi All, Can anyone explain why on the first line of my drum channel 10 there is CC101 0, CC100 0, CC6 2 and CC101 0, CC100 0, CC6 127. On some files I also have CC101 0, CC100 0, CC6 12. Will there be any noticeable difference if I alter or remove them? I use a Roland MC50 with a Roland SC8850. Thanks in advance..

See the Control Change Messages tables.
CCs 100/101 select one RPN; CC 6 then changes the value of that parameter.
RPN 0/0 is the pitch bend sensitivity. It has an effect only if you are actually using pitch bend messages (which is unlikely on the drum channel, any in any case you would know).

Hello,
Firstly, I would suggest that really only you can tell if these CC items will have any effect. By all means, try removing or changing them, and see (hear) what happens. You will NOT harm anything.
Do note that the drum channel (10) will be playing a number of different sounds, for different percussion instruments. For many of these, pitch bend sensitivity may well be totally irrelevant, so these controls will have zero effect. For some other instruments, there may be a small effect that may not be noticeable. Certain instruments, with more pitch parameter, may receive clear influence. The manuals for your units, regarding editing the percussion sounds, may give hints as to which specific sounds might be affected.
You do not suggest that these codes are ALWAYS inserted, you DO suggest that the codes are not always the same.. What is the difference between the music to be played between the times CC6 is 2 and the times it's 12. Are different drum kits selected? Ditto regarding when such codes are there, and not there?
These are very specific codes, and seem to have a specific purpose. They do not seem to be random. I would be more interested in trying to determine WHY they're there, rather than removing them when they do no harm.

Now I understand it. Just to verify - All the commands are before the hi-hat does the count-in. If CC101 0, CC100 0, CC6 12 is the last change before cc101 127, cc100 127 then the CC101/100 commands before that will be over ruled.. Here is an example of the drum commands on most of my songs. All in place before the count-in. CC32 4, PG1, CC1 0, CC64 0, CC7 127, CC11 127, CC10 64, CC91 110, CC93 0, CC101 0, CC100 0, CC6 2, and finally CC101 127, CC100 127. I am clear on everything except CC1 0 and CC64 0. Thank you for responding. Joe..
Joe,
Not necessarily overruled. Carefull
A number of common Controllers have their own number. Others do not, and have to be 'selected' first.
The 101/100 combo is selecting a controller, and the immed data 0/0 selects Pitch Bend Sensitivity. The same 101/100 followed by 127/127 prob selects something else (I know not what..). The CC6 value is the actual data to apply to the selected controller. If the exact same controller is selected twice, then the second one could well overrule the first, but if the first was selecting 0/0 and the second selects 127/127 then the second does NOT overrule the first as you're applying data to two different controllers via the same RPN mechanism.
Controller CC 1 is Modulation Wheel, while CC 64 is Damper Pedal. Again, certain percussion instruments MIGHT be sensitive to such.
