Diki,
I guess you could run both arranger engines at the same time..but, IMHO I don't think I want that...I just want to use one at a time,,maybe different one for each song, or even different one for the same song.. on different nights?

Korg uses MIDi PC's to control most arranger functions (into1,2,3, VARS, fills etc)
This is not a problem at all if you are using a MIDI foot pedal unit. All you have to do is easily setup a SET (most allow for at least ten sets of MIDI control setups) to control whichever kbd you are using, then select it depending on the kbd at the time.

If you wanted two arranger engines running at the same time (??), then it would be a problem.

The Behringer FCB1010 handles this issue in fine shape. If you are playing a song with Yammaha T3 select set A, Korg PA Set B, Roland G-70 Set C etc.

Where the BIG isue is = The MIDI implementation on most arrangers is very poor and very amateur.

Let's say you want to use a Yamaha T3 to play sounds on another MIDI instrument, say a G-70 (Korg PA, HW sound module, VSTi etc)....You can look in the manual for the G-70 and find the necessary MIDI bank/Program change message to send to select say a nice Sax...BUT YOU CANNOT program the T3 so that when you select a performance or sound in a style to actually send the correct MIDI message out!

That's what we need to tell the MFG's we want (along with other better MIDI implementation).

Any PRO synth can do this fine...The PA2XPRO being a PRO arranger can also do this fine and I use it all the time. It is the only one I am aware of that can.

When I had the T2 and a Kurzweil PC2R...I wanted to do this so I called Yamaha support to see how...they told me 'You don't need to do that this is a home keyboard and everything you need is in there already'...end of support call.

That's the attitude of the arranger Mfg's we need to change for us that want/need TOTL arrangers!
