Vquestor, yes it is possible to create an XG Wavetable. That would be a great deal of work in finding suitable sounds and then appropriately balancing them.

I started with sYnerGiGs which is a GM/GS wavetable which includes the XG drums in bank 127. The Yamaha Styles will pick an appropriate GM sound if it cannot find one in the appropriate XG bank and program numbers. For 99% of the styles you get a very good result. In others you may have to add a more suitable sound in the appropriate bank/program. Where I have expended effort on is replacing ordinary sounds in the sYnerGiGS wavetable with higher quality sounds, e.g., ordinary 2mb piano with Nemesys 70mb piano (converted from GigaStudio to Soundfont). The wavetable I currently use is approximately 128 MB (the original was 32 - 44 MB). It is, of course, not just the size of the sound that matters but also the engineering and the original recorded quality of the instrument in question.

Jos, you are right the standard is 0 - 127 but some wavetables come numbered 1 - 128. It is for this reason that VSampler, Audigy Soundcard, etc. have a provision to remap these banks and patch numbers. As I pointed out this is not a critical issue for me. Far more important is the correct drum instrument assignments with respect to the note numbers. I can usually find a way to pick up the correct drum kit, e.g., Jazz Kit, etc.

Jos, again thanks for all your help.
