AnaddrSynth is a sound synthesis tool comprised of three analog-modelling oscillator engines, three configurable oscillator banks, hi/lo/moving filters, a wah-wah effect, an echo/delay effect, iCloud patch/settings sync, and configurable attack-decay-sustain-release and modulation modules. AnaddrSynth supports Audiobus inter-app audio for recording with Garageband and sending AnaddrSynth audio thru effects apps. AnaddrSynth supports hardware MIDI keyboards.

These initial versions are foundations for future enhancements, with the following features planned: Real/Virtual MIDI, additional configurable oscillator engines, and various tools for new sound synthesis approaches.

Aka monkey dope ,


Thanks for letting us name patches ..now let us interact with the interface and show us some kind of description of what does what in terms of making noises and not just here is this kind of thing and it's for ..stuff like...plus this crashes a lot more than it already was! I have a feeling that the DRAW IT YOURSELF function which is still a complete mystery as to what it is or isn't doing is behind that. Finally this unstable mess is on the approved for IOS 8 list? Really?as well as the audio buss list?A synth that crashes seems appropriate for audio buss but is yet another road block.what a night mare for us PAYING CUSTOMERS.peace christo

Again - fun synth!!

Yeah, it’s a unique synth with the type of adjustment that old hardware analog synths have/had. It requires some attention span, heaven forbid. Hit or miss sounds, plus settings that work with iCloud, one of only two iPad synths that sync iCloud settings.
