Thanks to AMADEUS sound technology, the crystal mixer pre amplifier/effect system and the optional ‘eds’ tonewheel module, the Silverbird models offer the same fabulous sound quality and fascinating features of the large Böhm organs. If you already own an instrument with a keyboard, the Rack version gives you the full power of a Silverbird in a case, but without a keyboard. The Silverbird Rack is a full blown instrument with all the same features und musicality as the keyboard version. The playing features of the Böhm Silverbird models are way ahead of those offered by normal standard keyboards: per manual side (upper/lower) it is possible to play up to four different instruments, each of which can have its own user definable split and dynamic parameters as well as other playing features. If desired, it is even possible to further increase the number of splits and layers – an important feature for ‘live playing, reducing the necessity of frequent ‘preset changing’ While playing the Silverbird, you will be fascinated by its fantastic realistic sounds, generated by the newly developed AMADEUS sound system. With its 117 voice polyphony, numerous insert effects and warmth of sound, AMADEUS is an outstanding masterpiece among present digital sound generating systems. In between all of this, the nostalgic and modern organ sounds created by the integrated ‘eds’ drawbar system (has its own tone generating system), are a joy to the ears. Nine drawbar footages per manual side and two footages for the bass, as well as many of the well loved features such as keyclick, percussion, sustain, vibrato, chorus, rotor etc. are all included here. The drawbar sounds are set on the special display by use of the sound buttons that ‘double up’ as drawbars on the right side of the console. All sounds of your Böhm Silverbird are sent through the integrated crystal mixer with its effects, in crystal clear studio quality. Here you can make the best of the fantastic sound possibilities, from a wonderful solo instrument to a powerful orchestra, or from a solo stop to the full Tutti of a huge pipe organ. The sounds and presets of the ‘classic complete’ edition as well as further AMADEUS sound packs are also optionally available for the Silverbird range.
