Released in 1991 this one is probably our second favorite synthesizer next to the EX5. The thing that made this synth amazing was it's AFM (Advanced FM Technology). Not only could it read the DX7 patches, but the enhanced AFM allowed for even better FM EPs with a ton of expression. The other thing you will recognize from this synth is it's incredible A/D converters which really make the synthesizer sound warm and phat. You can still hear the digital edge, but it's mixed with a warm analog tone that made all of the patches just sound professional and organic. Highlights: • Standalone and AUv3 Compatible • Yamaha SY99/77 Virtual Sample Library • 18GB Library (11GB Lossless on Disk) • Includes all 256 Factory Presets • Includes all RAW Waveforms • Includes all Drum Kits --------- The Ultimate Recreation of a Legendary Synth Classic: • Factory Presets - You get 128 Factory SY99 Presets and 128 Factory SY77 Factory Presets • Raw Waveforms - We give you access to the RAW Waveforms so that you can re-create some of your favorite patches. Our synthesis is powerful enough to get very close! • Capturing Nostalgia - Most of our presets use the exact wave layers as the hardware, which allows you to tweak to your liking. When needed, we used the sampled version. • Taking it to Another Level - Because our synthesizer is a bit more powerful than the hardware, you can now create presets that rival the hardware. • We sampled the factory presets with the effects on to capture the "exact" nostalgia of the hardware. --------- Standalone vs Pure Synth® Expansion - Standalone version has the black skeuomorphic interface - Expansion Unlocks inside of Pure Synth® FREE Player (https://apps.apple.com/us/app/pure-synth-platinum/id1459688500#see-all/in-app-purchases) - The Expansion includes the iPhone Version and the standalone does not - The Expansion includes the dynamic modulation from Pure Synth® - The Expansion allows you to mix and match libraries with one single interface ------- Sample Size and Space ▪ 18GB RAW Sound Library Before Lossless Compression ▪ 11GB Actual Size on Device After Lossless Compression ▪ 2GB RAM or Higher Required ***Lossless compression is a way to compress audio files without losing quality. ---------------- Device Specifications: ▪ 2GHz ARM Processor Recommended - iPad Pro 12.9 and 9.7 in, iPad 5th Gen, iPad Pro 12.9 in.
