Years ago I used a Yamaha PSR 6300 with a sound module for brass, another for strings, and a third for bass and drums.

I got to see/hear a Pro using a KN2000 with two small sound modules, which he controlled with two volume foot pedals.

The sonds were great, but ---- In my opinion they take away from my playing. (live)
I can see their value if I were recording (audio)or sequencing.

A good keyboard like a Tyros or a KN7000 gives me all I need. And the new ones are getting better.

Have a great day, John C.
