Ketron XD9 was released in 2005. This synthesizer is an improved version of XD3: it has a 61-key keyboard, modulation wheels and 2 large built-in speakers. XD9 instrument has a 64-note polyphony.
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 part features adjustment of volume/transpose, effects, and the right one offers the selection 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 navigating. In a multitimbral mode, XD9 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 include 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. Besides, two effect processors can be used to make the sound complete: reverb, chorus, distortion and delay.
