I recently purchased a PSR-550 and am wondering if there is any way that the left hand (voice L) can be held until another chord is played in the auto-accompaniment mode. I previously had a Yamaha FX-500 organ which had memory.

Thanks,

Tom,
I also own a Yamaha PSR550. I wasn't aware that you could play a left voice and auto-accompaniment at the same time. I will check this out tonight and get back to you, if I have a solution.
In the meantime a encourage you to join the general arranger keyboard forum. There are many Yamaha users on the forum, actually more then any other manufacturer. There are 2 PSR550 owners on this forum as well. Myself and Squeak_D.
Congratulations on your recent purchase, I believe you bought a keyboard with the best value for the price you paid.

You can play a lower voice and arranger at the same time (you already knew that), but not sure if there is a way to hold the chord till your next change. My Roland EM20 can do this in organ/split mode only. I suggest you post your question in the "General Arranger Forum"
