Pure Synth® Platinum is NOW FREE!!! It has evolved into one of the only Virtual Instrument Players on iOS and has emerged as the only substitute for your Rompler/Synth needs. All engines are fully capable as a romper, synthesizer, and wavetable mangler. We have a simple automation and modulation system where you simply touch+hold on any parameter and it will learn your MIDI CC commands and you can assign modulations to any parameter, including the effects. Our synth also includes all of the VKFX Suite from Overloud™ and we are always adding new effects that we add free from within the app such as the new effects below: - CloudVerb Creatmospheric Reverb - PhatFilt - Analog modeling Filter and Feedback - Talkbox® - Vowel Sounding Talkbox effect - iFX Amp - Realistic Amp Sim emulations Virtual IAP Expansion Setup Everyone remembers the famous samplers that we love with branded expansions and the unlimited ability to expand. Now that Pure Synth® Platinum is a free download, you can pick and choose which expansions you want to use. Freely purchase any expansion and most of them don’t require other expansions in order to run. We have plans for many more expansions and with our ability to store samples on external drives, your iOS device becomes the one stop shop for all things samples and synthesis. Not only can we add new sounds, but new features, such as the ability to load in your own wavetables or load in your own sounds in the future. Existing BASSalicious and FM TiNES Users Existing users of our FMT and BASS2 can go to the settings and look for the APPLY CROSSGRADE option. This will allow you to unlock those same sounds from within Pure Synth®, so now all you need is one synth to access all of the sounds.
