Greetings!

I'm a newb to the forum and to MIDI, but have been engineering on and off for years now. I am currently running ProTools LE 6.9 on a G4, and I have a quick MIDI question:

I am trying to use a MIDI keyboard/controller to record a stereo track of BFD for a demo. Prior to using the keyboard I simply wrote in all the MIDI notes manually. Anyway, I'm wondering if I can "overdub" MIDI, meaning can I take a 1st pass on my MIDI channel to record kick and snare, and then go back and "overdub" the hihat / cymbals on the same MIDI track without erasing the pass of kick and snare that I already recorded? Basically I'm hoping that I can use MIDI and BFD to operate very similarly to how an old school drum machine works. Any help or advice would be great, thanks!

As far as I remember (I worked with PT midi about a year ago) if it is in overdub, it will not overwrite anything & you can keep adding notes to yer lil' hearts' content. If you don't like the notes from the last pass, you can cntrl z & eliminate it & then continue with your overdubbing.

So you are confirming that there is an overdub mode, which is awesome! But, I'm wondering if you know what option/setting puts midi into "overdub" mode, I'm looking around the midi options and I'm not seeing anything obvious. Anyone know? Thank you for the response!

Okay, after doing some research and some noodling around I discovered the "MIDI merge" button which does what I was asking. However, I'm having trouble finding this same button in Pro Tools LE 7. It seems the options in the drop down menus have changed dramatically in spots. In LE 6.9 there was an option in the dropdown menus titled "Transport Shows..." that allowed you to open many more options up for the transport, and I can't find that same menu in PT 7! Can anyone help?
