I'm not big on midi, too complicated for my feeble brain, but I do try to use it on occasion... but if I have any midi track (usually for drums or percussion) on my project I can't turn them off on my keyboard (Casio Privia PX-300), so that if I try to go back and play keyboard type part, piano or whatever, the keys sound both the keyboard and the drum sounds at the same time... I've turned local on and off, but that's the only suggestion I could find with a search. They only way I've been able to fix the issue is to dump my midi track to an audio track and delete the midi track, then reboot the keyboard. What am I missing?

Once you have recorded the midi drum track, turn input echo off (it will change itself to auto thru, but that's ok).
Alternatively, you can select a different input on the midi drum (None).

Hmmm, none of that worked... I have the Input Echo off, it does say "Input echo = Auto thru", that didn't fix the issue, and the midi Input won't let me change it to None... when I click it the drop down it says I've chosen None, but Omni remains in the window. The keyboard is still playing drum tones and key tones at the same time.

Make sure input echo is turned off on the drum track, not the one with the keyboard.
 
Try setting the drum track to respond to MIDI channel 16. I doubt the Privia is generating anything on that channel.

Your Casio Privia PX-300 does not support Local off which is how one normally turns off a midi instrument.
 
Try setting you keyboard to transmit and receive on another channel.

Setting the channel to 16 works... is that a work around or sop?

Both. Don't know why turning off MIDI input echo doesn't work; it always works for me. In any event SOP is to set the receiving and transmitting channels differently so they won't communicate. Turning off input echo blocks MIDI data from arriving at the track, which is a more convenient solution.

Sadly, and frustratingly, I've never been able to get a handle on midi, so I use it sparingly, I was just hoping for a drum track with more precision... I'm also fighting with the Piano Roll method of inputting, (haven't figured out how to separate the parts for processing), between that and midi, I think I'll go to a movie. Thanks for the help, looks like a decent work around for me.

I think when you start with Midi if you are not totally sure of what you are doing it can seem daunting - i know when i started with Midi back in the day i found it very challenging - but its worth persevering with because after a while all becomes much clearer! Instead of trying to record something specific why not just set aside some time just to play with some Midi and see if you can start to fathom it out - that's how i started to get to grips with it - i found that a better way than trying to sort it out when i wanted to record something i had in my head - and if you come across some things you can't sort out I'm sure there will be plenty here who can help with specific issues - cheers Nigel

The good news is that you are getting close to mastering MIDI.  Once you get the echo thing resolved and then understand MIDI channels, you will be able to do a lot.
 
You can then learn a few controllers here and there as you need them, read up on quanitizing, and you'll be pretty close to a MIDI expertl
 
For what it's worth, in Preferences | Playback and Recording | Playback I have a check by "Always echo current MIDI track."  Whenever I select a track, that track responds to my MIDI keyboard.  If I start hearing other instruments, I go to them and "unblue" them by turning off Input Echo.
