Hiya Bernie
Good to hear from you - practically all the songs you heard me play at the jam were not using standard presets.
Over the last ten years I have scanned the internet for style files (rhythms) which are specific to particular songs irrespective of which type of keyboard they were produced for originally - the largest proportion that I have found started out as Yamaha style files.
I then convert them using Styleworks Pro so that I can use them on my Technics KN7000 often with a bit of tweaking needed to make them sound OK - and I now have a collection of the RIGHT sounding style files for over 500 hits covering the last 50+ years.
It does mean that when I'm playing publicly people instantly recognise the song that I am playing and sing along or tap their feet.
