Kurzweil SP4 and SPS4 Keyboard Sound Editor

The SP4 SoundEditor is a full-featured Editor/Librarian and Sound Development tool designed for Kurzweil SP4 keyboards. SoundTower's Editor greatly expands the editing experience by displaying every editable SP4 parameter in a series of logical, easy-to-use graphical interfaces. SoundEditor allows you to create, edit, organize and store SP4 Programs, Setups, and Effects. Through a standard MIDI connection (DIN or USB), SoundEditor can receive and transmit individual Programs, Setups, Effects, or entire banks to the SP4.

The SP4 series was originally developed and introduced to the market as a piano keyboard with a very limited editing capability. This has changed with the introduction of the SP4 OS update 2.10. The SP4 is equipped with a very similar sound engine as the PC3LE synthesizer and with permission and help from Kurzweil Music research group - YCRDI, we have designed the editing software that opens up many features of the PC3 engine for SP4 users to enjoy. Unlike the PC3LE, the SP4 does not offer much of editing on its front panel. You will be amazed what you can find inside this rather simple looking piano keyboard. To your surprise, you will be able to access and use many features that normally are not listed in SP4 specifications. The editor will make possible for you to reach inside and unleash the amazing power of the Kurzweil sound technology.

Please note! The editor is not a software instrument and it will produce no sounds unless connected with the Kurzweil SP4 series keyboard.
