The base Ketron keyboards and sound modules are great units as they come right out of the box. However, if you are looking for more styles and sounds to add to your Ketron, you want the AjamSonic upgrade package.
The AjamSonic Upgrade Kit adds over 600 styles, 200 sounds and over 2,000 songs (MP3, Wave & MIDI) that you can use as backing tracks.
