The Ketron SD90 is a rack-mounted arranger module from the Italian manufacturer that has built a devoted following among professional entertainers with its exceptionally realistic instrument sounds and musically sophisticated accompaniment arrangements. Unlike keyboard-based arrangers, the SD90 is a sound module that connects to any MIDI controller, allowing performers to use their preferred keyboard while accessing Ketron's acclaimed sound engine. The module features over 480 sounds with Ketron's proprietary sampling technology that focuses on capturing the complete tonal character of each instrument. The style library of over 350 patterns features arrangements crafted by professional musicians, with a natural, musical quality that avoids the mechanical feel common in less refined arrangers. Real-time arrangement control allows adjusting instrumentation, feel, and density during performance. The vocal harmonizer processes microphone input with up to five-part harmonies. Audio file playback and recording support MP3 and WAV formats. Multiple audio outputs enable flexible PA system integration. MIDI connectivity is comprehensive with USB and traditional DIN connections. The compact rack format fits easily into mobile performance rigs. The SD90 is ideal for professional entertainers who already own a quality keyboard and want to upgrade their arrangement and sound capabilities. The module format means it requires a separate keyboard controller, adding complexity and cost to the complete setup.
