My name is Thomas, I am from germany and I love my SP4/7.
I know, this is an old keyboard, but it is very useful on stage.
I notice, that most of the forum-contributions at KSETLIST are concerning PC3(K), Forte or SP6.
As you can read at KURZWEIL.COM, most of the PC3-sounds can be load into the SP4, PC3LE and SP5.
But insider know: There are some limitations!
So I talked to FRAN, who is the administrator of KSETLIST, and discussed a separate forum/topic inside KSETLIST concerning only SP4, PC3LE and SP5.

Please let me know, if you think this would be a good idea?

Thanks
Thomas
