Ketron XD3 was released along with XD9 in 2005, and it differs in that the latter one lacks a keyboard, modulation/pitch wheel and sound amplification system. XD3 has a 64-note polyphony, and it is a music module that will provide an easy workflow, and will translate the user into a new sound space.

The front part of the device is divided into several sections: at the top there is a display with all the most important information about the selection of banks/effects and editing, the left one is for adjustment of volume/transpose, effects, and the right one is for the choice of voices (piano, organ, guitar, and even synths/pads). The first section is a digital panel for selecting patches, and the second section with buttons is intended for configuring presets and menu navigation.

In a multi-timbral mode, XD3 works with GM-banks (292 patches) which sound quite realistic. In addition to GM-banks, you can find 290 preset patches, 110 user and 24 drum kits. The first 3 GM-banks offer different voices. A separate 4th bank is derived from GM. Several buttons on the control panel are used to program the presets.

"Panel" voices can contain up to 3 layers, where each layer represents one sound from the GM bank. In some samples the performance is composed in a similar manner. In addition, for final sound shaping, you can use the effects: reverb, chorus, distortion and delay.
