Almost everything is fantastic. – Audulus 3 Review

This is by far the craziest Synth you’ll find on iOS as long as you’re willing to “program” your sounds. Moog’s Model 15 is a great place to begin with Modular Synthesis and Audulus is certainly the next and ultimate step. If even Model 15 seems too confusing to you, then perhaps start with an even simpler modular synth: “RippleMaker” by Bram Bos. As for Audulus, I have only two complaints: 1) please, AUV3. 2) I use it on my iPhone and you have to get EXTREMELY CLOSE to be able to connect node outputs and inputs, please give us a way to define how far we need to be to switch to “node connection mode”, as it is quite annoying to have to zoom in to a point where the node I’m trying to connect occupies almost 70% of my screen: it’s hard to connect then this way. Both of this issues require fixes ASAP, but regardless this is a jewel of an app, so just get it. You won’t regret it, and it’s cheaper than the Model 15 (which you should also get tbh).
