Hi Machetero,

I cleared this previously with AJ for my own benefit. If you run on OS 4.0 or higher & you upgrade to AJAMSONIC, you can upgrade normally on any new released Ketron OS.

I.o.w. when OS 4.2C becomes available, I'll install on my AJAMSONIC Audya as per the normal way. No more conflict between these two products!!!

Keep well my friend,

Henni
