oops. I need to amend what I said in my previous posting:

The PSR2000 actually 'automatically' memorizes the arranger button status settings from what was set before the last kebyoard shutdown. You Do'nt need to activate memory via Registsration Memory command like I previously had thought. Here's the trick though. If you want to change the ACMP button status light (on/off) upon initial keyboard bootup, you MUST press the 'OTS Link' button and turn that on/off too, because these buttons are directly linked. If you just change the status of the ACMP button and not the OTS link, the new ACMP button status will NOT be memorized. The 'OTS Link" button also controls and links the Sync Start button as well. Basically the OTS Link, ACMP , & Sync Start buttons go together on/off as a team. If the OTS Link button is on/off, the other two will share the same status too. I think this makes sense now. I think it's time for me to get some rest
