SEQ to composer copy

Someone mentioned recently that 'SEQ to Composer Copy' was a great way to make a style file out of a midi. Easy enough to find that facility on my KN7000. But looks a bit complicated after that...
Anyone got a simple set of instructions for using it?

I recently purchased a second PX44 piano with all working keys in order to replace 1 key that has stopped working on my first piano.

From what I can tell this organ has the plug in boards the same as the U60, U55 range of organs. These sit in a card frame to the rear of the keyboards. As such it is highly unlikely that it is repairable. I have done any number of these in the past and a…

I have some spare boards for the u60 range so it might be worth while trying a swap. I think I have a ptf board that I can send you if you want to try it. I'll dig it out of the workshop!

Re: Technis SX-EX70M double notes ?

I could speculate about this but I would think it needs an engineer to check it out. All these old organs have issues and they all need a few new bits to keep them working properly.
