I own a PA-80 and find I need more polyphony.Whn in the ballad mode and I bring in the strings and the brass, the drums drop out. Many times going up & donw the keyboards, notes drop out. I'm thinking of the tyros with 128 not polyphony. Any ideas, comments? Is the tyros better. I was waiting for the PA-1, but it only has 64 note polyphony. Again, any comments, ideas?
