Monosynth Mobile Master's Program

Since the original MS20 (or the mini) isn't really something you carry around and start playing at, say: the airport, or in a car, this app gives you a really close emulation of the synth and a sequencer to experiment with and get astoundingly life-like results. Really impressive app. Great reproduction of panel, sonics, character, and functions/features.
When you aren't with your synths, this app furnishes you with limitless and useable synthesis power. I even tried some tricky patches from using the hardware version (namely: the paraphony via sample and hold trick), and it does just what it should. If you're a synthesis dork like me, you'll likely love it. Five star app.

Best iOS synth out there

I love this synth. I was considering getting the hardware version but thought I'd try this before shelling out the money. The presets are great but the real fun comes with making your own and experimenting. There is definitely a learning curve and it certainly helps to know what the knobs and patches are for but, you'll figure it out just tweeting around. People have things to say about Korgs pricing and whatnot but the fact of the matter is its worth every penny. Amazing sound and endless modulation are what this app is all about.


Having spent many hours with its analog counterpart, I find myself increasingly impressed by how well this manages to emulate the MS-20 hardware. They sound and behave in very similar ways, I've no hesitation in declaring this app to be a fine substitution the hardware in almost any context. There are differences, to be sure... Both hardware/software have their benefits and detriments... But the fact remains - this is a truly impressive emulation, an incredibly powerful modular synthesizer, available on a touchscreen device. This future I like very much.
