The sound engine of the legendary Waldorf Streichfett hardware is now available for iPad including AUv3 format. The Streichfett takes you back to the days of the legendary String Machines. In the old days, there was no choice – to create a massive wall of sound, you simply needed a String Machine. It was the time when composing contemporary music had no resemblance to doing your annual tax return on a PC. It was the golden years of rock and pop, when even keyboard players simply plugged their instrument into the amp and started playing, instead of labouring over endless preset lists in search of the perfect sound. Now there is Streichfett – and the good old days are coming back. Experience what a real String Synthesizer sounds like. Experience how a homogeneous, extremely dense, floating web of sounds can be created from a raw, basic electronic sound in just a few simple steps. Streichfett combines the best of the previously extinct species of String Synthesizers of the 70s and early 80s. Its dual sound engine features a fully polyphonic String Section and an eight voice Solo Section, which is essential for recreating classic movie sounds from the 70s and 80s. The Ensemble Effect provides depth and movement to the String Section, while the Effects Section adds adjustable Phaser and Reverb effects. Additionally, the Animate Effect can be used to modulate the Strings Registration, allowing spectacular sound morphs. The Solo Section offers presets named Bass, E-Piano or Clavi, and just like with a typical String Machine, the sound has little to do with that name. Instead, these are shimmering and slightly percussive sounds that blend well with the String Section. Although the User Interface is simple and easy to comprehend, it controls a rather complex sound engine which is capable of delivering rich and creamy pads unlike any other instrument.
