The versatile Waldorf synthesizer classic Blofeld now also available for iPad including auv3 for hosts like Logic, Garageband, Cubasis, AUM and others. With the Blofeld app you can also control your hardware and it is compatible with existing Blofeld soundsets. The sound generation of the Blofeld plugin delivers the typical fat and rich Waldorf sound character that so many Waldorf users worldwide love when they are playing their Blofeld, Q, Q+, Microwave, Microwave II/XT or even the flagship, the Wave. The secret of its sound is a powerful wavetable engine that enables these intense and expressive sounds. This unique synthesis system is based on the revolutionary PPG synthesizers of the early 80s. When you hear the Blofeld for the first time, you’ll immediately remember those edgy, assertive or bell-like timbres that have been an integral part of countless worldwide hits since the PPG era.
