I would like to ask you for some help again. In the meanwhile SD1 serves me well and I enjoy playing it very much!
Is it possible for you to provide info on the following two questions about SD1?

1. I use 6 switch foot pedal. I would like to ad an extra switch on my own. Which pins on DB15 connector should I use and what kind of switch is compatible with Ketron?

2. Does Ketron have any charts of how preset voices were made in 3.0 release? I would like to reprogram some of 4.0 presets to sound like in 3.0 and I would like to avoid reloading SD1 back to check it.

Thanks for any help.
