Ketron has an unusual tradition: synthesizers with a chromatic keyboard have something in common with infinity, with the number 8. SD8 is another product with a corresponding keyboard, and of course, this instrument definitely stands out among the rest in its category, owing not to internal capabilities, but to the keyboard.

Unlike other models of this line, SD8 has a chromatic keyboard: the right zone is limited with 52 keys, and the left one – with 120 for basses. Other characteristics remained the same: 2 large built-in speakers, a central panel with a wide control and a graphic TFC-display with backlight and dimensions of 240x128, and, of course, a pitch/mod joystick.

SD8 has a wide range of sounds: PCM samples, 290 orchestral sounds, 24 drum kits/62 sets of live drums, drum grooves, analog waves (sawtooth, square, sine). Moreover, the synthesizer has 120 programmable user voices with envelope control, LFO, wheels, aftertouch and effects. SD8 also has 198 kinds of auto accompaniment and 198 custom styles with programmable parameter settings.

The rear panel of SD8 features inputs for stereo headphones, 2 line inputs, a microphone input, MIDI input/output/thru, 2 outputs, and connectors for sustain and volume pedals. The synthesizer boasts a variety of effects, ranging from reverb/delay to distortion/wah-wah. The sampler allows you to store up to 8 MB of 16 bit/44.100 kHz data. There you can edit the time, loop type, reverse and delete.
