Rikki, I guess your are right. I won't rest until you acquire a very high quality 76 note controller which replaces all your keys including your Clavinova. Then and only then will we beable to say that Rikki has arrived and the rest of the world is standing in her shadow!!! One could say this even if she kept a 49 key controller for travel or other purposes.

Yes, it is alot of work to convert the GM500 wavetable to the Kontakt format (or Soundfont). The other disadvantage is the the size (500mb). This ideally should reside in your computers memory for use by your accompaniment software. The larger the size the longer it takes to load the wavetable and the less room for other things. Oh well!!!

And yes, it is alot of work changing all the styles to meet the GM standard. However, doing so (once) frees you to use many available GM wavetables. You may still need to change volume levels and effects but this is easy to do.

Yes, if you use Kontakt and very high quality instruments then you need to have second HD from which such instruments are streamed as you play.

But you can stay with your Another XG wavetable and only modify or replace those instruments you feel need to be improved.
