Hi Tony.

This is nothing at all like Ketron. Not even close. This is one  issue that has only popped up since the changes made in os 4.2 regarding Linux Sampler a few days ago and no doubth in another few days Domenico will have fixed this and a patch online.  

The level of progress made in this part of the forum would put ketron to shame in a massive way. I kid you not. More gets done here in one month than ketron could do in one year. 

Regards
James
