The Cinematic Machine Aparillo is an advanced 16 voice FM synth tailored for complex sound structures , majestic motions, moving and evolving soundscapes and atmospheres that are perfect for film, TV or games. It‘s not limited to the conventional fm sounds but also delivers a huge range of styles from basses to brasses, pads to leads to even percussion. ••• SYNTH ••• It is based on two interacting FM Synthesizers capable of forming the most complex timbres. A clever arrangement of synthesis, wave shaping, filtering, FX and modulation unfolds into a serious sound design tool for epic sonic creation. Aparillo uses many parameters that can be modulated for individual adjustments PER voice. Each of the sixteen voices interact with almost two dozen targets in a variety of ways for a continuous transformation and to create endless rhythms and melodic progressions. ••• FX ••• The integrated effects include a free-signalflow Filter/Spacial Comb device, a polyphonic Auto Pan with multiple waveforms, the obligatory Delay, our finest Reverb algorithm, and a Sugar Bytes innovation, the Spacializer. This is a very special breed of delay based effect, which can work as a delay, reverb or tuned comb filter and can add room, plucked strings or even pinged percussion to your sound. ••• ORBITER ••• The superstar of Aparillo is the Orbiter, an instinctual "mass-controller" you move through Aparillo's endless sonic universes for one-touch sound morphing. That finally gives you unlimited control over new grounds of sound manipulation. Aparillo for iPad will seamlessly integrate with your mobile studio setup. We built in MIDI support (Virtual, Network, External, Bluetooth), Audio Unit v3 and Ableton Link. Syncing your presets to use them accross other devices couldn't be easier with iCloud.
