Rikki, you are probably correct about the PSR3000 styles, they trigger Mega Voices and may cause other sound generator to produce undesired results. In general, I have been waiting for a sample player software that has superior sound quality and ability to accept program changes. So far it looks like Bandstand may be the only one that can do it and if I purchase it, I will then experiment with a configuration that will give me some sonic benefit (over my PSR3000 alone). If I can only improve my lead voices, that would be great, as long I can trigger the sounds using my keyboard buttons as usual and not have to touch the laptop. Hopefully it's possible with the use of MIDIOX or a similar program that can remap the program changes that my keyboard is sending out to trigger the correct software sounds. PSR3000 has ability to turn off local control for some or all internal parts. So, that's the plan for now.
