Channel 10 became the default MIDI standard for the primary drum kit years ago. Eileen is correct about Channel 9. It carries spare percussion in any form. The Classic example is when a singer or similar band member on the live stage plays a shaker or tambourine in the chorus parts. That information would be recorded to Channel 9 if you were doing the same thing on the Genos.
Edit
I have no idea why the word Classic is capitalized in this post. Another tech glitch??? They seem rampant everywhere these days!!
It wasn't a tech glitch, Lee. As you probably already know, we censor words using an administrative tool. There was a time when a lot of Classical music was being posted on the forum and the word "Classic" was used in the topic title or music book title. I was constantly editing posts of this nature, which was taking a lot of time, so I solved the issue by censoring the word Classic and replacing it with the word "(C)lassic". This happened automatically and saved me a lot of time.
I just removed the word from our censored list, so you will now see that the word "Classic" is lower case in your post and correct.
I also had to enclose the upper case "C" in my own word "Classic" above in parentheses, or it would now be displayed lower case. I hope this makes sense to you, Lee.
