Squeak.....Yes the Nylon Guitar & Sweet Flute are an ideal example of your tip. In most cases the manual tells you about what buttons do, but does little telling you how to do things on my 9000PRO.

One of the Yamaha demonstrators gave me tip about adjusting the panel voices. For demonstration purposes they set Right hand voices on setting 20 - 45 DSP Hall 3 for most voices. Reverb is set to zero when using DSP as it will clash with the effects provided by the DSP. I have experimented with this and in most cases there is an improvement.
