Scott,
thank you for the links: I will check them for sure.
Re. the songs on my website, "Hold on I'm coming" and "I left my heart in San Francisco" were done with the Ketron SD1 (they are both a multi track effort). All the other songs were done with the Tyros, live, i.e. without any overdubbings or post-editing (you can hear a few dirty notes here and there... )
