I'm not real Midi Savvy, so if I'm right drums is on 10... How would I change everything so that each would have it's own volume.??
You will be midi savvy by the time you figure this out John or you'll wind up giving all this up and take up lawn bowling.<grin>
The reason everything changes is
because all the drums are on Channel 10. Change one you change them all. After you split the drums you then have to manually change all the channels. But, but what about my synth you ask? Right, you have to reconfigure that too but my synth has all the drums on Channel 10, etc, etc so now what? Now you're getting into the real midi stuff, not the simple baby steps for noobs. A good midi drum module has all the drums on separate channels so with one of those all you do is match them up but that drum module is a completely separate synth just for drums. Therefore this is not a simple mouse click or two and hit play. Oh no, you have to do some real work like a recording engineer would.
Welcome to the world of digital audio recording.
So maybe you want to rethink this whole splitting out the drums thing? There are reasons why things are initially set up the way they are but these programs allow the user to get as deep as they want.
Now that I've scared you a bit there is a decent workaround you can use while keeping the drums on Channel 10. In addition to volume there's a midi control called Velocity. Velocity is based on how hard an instrument is hit, plucked or in the case or drums banged on. The higher the Velocity, the louder the hit. The only problem is how hard you hit something can also change the character of the sound but for most basic drum kits in a simple synth, changing the Velocity and leaving Volume or Expression alone can work because changing Velocity is not channel dependent. In a midi drum kit each drum is considered it's own key and piano keys have different Velocities all the time.
There's issues with that too that requires further explanation so I'll leave it here for now and just ask you to go to the Piano Roll window, hit the Help button and read about Velocity.
But, (do you see a pattern here? Lots of buts) this is only using Velocity as a substitute for volume, what about EQ? That is channel dependent so you're back to that if you want to EQ say the cymbals alone.
Like I said midi is tricky. This is why when you look at a picture of a studio control room you see this huge console with a gazillion channel strips. How big is a drum kit? How big do you want? It could be 20 different individual pieces. Then there is the percussion station, that could be another 20 so if you want all that on separate channels with individual control that's 40 channels right there. Obviously most people don't do that, they set up subgroups.
And that is yet another discussion.
