You're dealing with a TOTAL newbie here. We use the CTK-691 with our orchestra to fill in instruments we do not have such as the harp.
We do a lot of Baroque and Renaissance music and really could use some good classic organ sounds ... not the full-blown church and chapel organs that come in the keyboard, but simpler ones that emulate a portative organ.
Are there any sites where we could obtain these? Is it possible to synthesize our own sounds?
Any help will be super appreciated.
