Ketron SD4 was released in 2008. It is a music module that will provide an easy workflow, and will welcome the user into a new sound space. The front part of the device is divided into several sections: at the top there are panel presets, just below there’s the 3-digit led display and 2 groups of buttons for monitoring.

The first section is a digital panel for selecting patches, and the second section with buttons is intended for configuring presets and menus navigation.

In a multi-timbral mode, SD4 works with GM-banks (128 patches) which sound quite realistic. There are 4 bank instruments and 32 drums. 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, two effect processors can be used to make the sound complete: reverb, chorus, distortion, delay and Leslie effect.
