The SP4 is the little brother of other Kurzweil synths, but nevertheless it has great sounds and digital processing effects onboard.
I have generated banks of User Setups for the SP4 series using combinations of existing Programs and onboard effects. It's programming at it's most basic, but the results from this little synth are great.
I couldn't work out how to upload the banks to the "ksetlist", but if there are any other SP4 users out there - feeling neglected in the shadow of the PC3's and Fortes of this world in terms of patches available - I am happy to share them.

P.S. I worked out how to upload my SP4 User Setups (SPSetups) banks. They are in the Volumes/Compilations area of the site.
