Once Kontakt 2 becomes available I will see whether it can load a GM wavetable. If it can I will then convert the whole of GM500 including the drums and use one instance of Kontakt for the accompaniment and another instance of Kontakt to run my melody parts. This would require converting the Yamaha styles to the GM format - especially the drums. Once I have this done I will likely retire from technical matters and play music until the angels come calling for the old man.
