rb,
I just tried the PA80 in the 61 note size and it's snug, but it fit. I had to push the back down into the case, but I think it will stretch a little after it is used a couple of times. The case I have been selling is the 76 note model. When the PA80 goes into this one there is 8" of extra space but this could be used for pedals, mics, etc. The nice thing are the two sewn in velcro staps which hold the keyboard in snug. These two 4 1/2" straps have nice pading which hold the keyboard solidly in the case. both cases have this. I would prefer the larger 76 note case, but the 61 note should also be OK. It is a tight fit however.
The total length of the 61 note is 44 1/2" vs the 76 note at 53".
