Hi Diki,

You are absolutely correct. There is no way to add Sample RAM to the Motif Rack. The original Motif Rack will only accept 2 Plug-in Boards of the type PLG-150 and PLG100.

Some of the Custom Voices were created utilizing the built-in Synth Engine and modifying the stock wave forms. They do not require adding external samples. The AXXE Guitar Voice Bank is one such example.

The ability to add external samples via User RAM should now become a standard feature on any Arranger/Workstation/Rack.

I was playing on a Yamaha S90ES 88 key weighted action keyboard this afternoon at our Guitar Center. I kept dreaming of one day having a Tyros3 in this casing. That will be the ultimate arranger.
