About this app

AMB-R is a simplified and alternate take on FM synthesis that fits snugly in your pocket. Shape crystalline sounds, noisy textures, or sharp basslines anytime and anywhere. Further refine and sequence your creations and parameters at home, in the studio or on stage or just use AMB-R as an external synthesizer via USB MIDI controllers or a DAW.

Really easy to get cool, unique sounds fast...has more of "a vibe of its own" in a really good way than just about any other synth app I can think of. Works well with receiving midi from external hardware. Built-in keyboard and 4x4 grid are each fun and cleverly designed. It's easy to wish for a little more from the sequencer, but I appreciate that this thing is mostly just trying to be a great intuitive synth that's fun to explore and consistently inspiring. Happy to use external sequencing

Really nice enjoyable app, only a couple of key issues. Weirdly enough I feel like the app is changing my beats to a certain extent, like it'll add its own spin on it? Kinda odd, definently not a 1:1 replica of what I'm tapping in though. As well as the fact I can't seem to find out how to mix sounds! (for example adding bass from the Roundbass Sound Pack to a song made with synths doesn't work, it makes the whole song bass) Other than that an undo and redo button would be nice! Fantastic app 💯

Thanks for the review and feedback, much appreciated! The recording feature of the sequencer uses Quantization, the process results in notes being set on beats and on exact fractions of beats. Also as with a lot of hardware synths, AMB-R let's you create and play only 1 sound at a time. There are no tracks like in a DAW you could mix together.

such a fun app! I use a mobile DAW as well. The ability to do automations and export your sounds is amazing on this you can basically make songs on the go!. For a free app you can't go wrong. The creators of this app could charge at least 30$ for this!
