You *can* save the "mute" on any or all accompaniment channels as part of a registration on the PSR 740. You can choose one or more of the four variations (Registration Memory buttons 1-4), mute the channels you want to mute, and then save that to one or more of the four Registration Memory choices.

If you're going to be using the same style throughout your song but want to designate different lead instruments (Voice R1 and/or R2) for each Registration Memory, you can press the "Freeze" button. That will allow you to keep the style settings that you have in the current Registration Memory while pressing buttons 1-4 to quickly access different instrument combinations.

Regarding how to record an introduction without accompaniment and then go to playing with the accompaniment, I have found that I could do this in playing by doing one of the following:

With Accompaniment On and Sync Start On, play the introduction on the right side of the keyboard only (i.e., to the right of the accompaniment/Left voice split point). When you're ready to start playing with the accompaniment, just start playing in the part of the keyboard *below* the split point. That should automatically start the auto-accompaniment using the style you have set.

  If you want to use the *whole* keyboard to play your introduction, try this. First, turn Accompaniment Off, *but leave turn Sync Start On*. Mute channels 9 and 10. (Otherwise, even with Accompaniment Off, Sync Start will start the drum channels as soon as you press a key, even in the right hand.)

When you get to the point in the song where you want the accompaniment to turn on, just turn Accompaniment On again and start playing on the left side of the keyboard. Since Sync Start had been *on* all along, even though the two drum channels were muted, turning the Accompaniment on again starts all the other instruments of the style. You can then un-mute channels 9 and 10.

Alternatively, you can save the style and instrument choices you want to use to different Registration Memory buttons. When you're ready to play (or record), be sure you have the correct registration loaded and that the Memory light is green, not red (so that you can access your saved Registration Memory settings).

Again, with Accompaniment Off, SyncStart On, and channels 9 and 10 muted, play your introduction. Then, when you're ready to start the auto-accompaniment, just press the button for the settings you want. That should start the *complete* style, including the drum channels (unless you saved the Registration Memory settings with those channels muted).
