Customer Reviews


This is a brilliant app, possibly one of the best you can buy. It's very very close to an MS20. My original MS20 owning mate went so far as to say, "it's an MS20...each one has it's own nuances, so it sounds like whatever machine they based it on". It's brash, wild, unapologetic and stands out. I'm sure it could sit in a mix but it's at its best when it's being pushed. With the routing options and slightly unconventional setup it's great for tweeking and coming up with unique sounds. The step sequencer is perfect for techno style bass lines and the drum machine section is brilliant, essentially making this a multi timbal MS20. The drums are all MS20 but don't worry, the presets give you some good starting points, from there, get playing. It's fun. It makes me want to experiment and touch it and that is a great recommendation. For me, it's a techno beast, nasty synth noises, weird stuff, cutting leads and bass lines are where it excels. The drums are fantastic too. It has a grit and originality to it that makes it very appealing to my ears, and I'm sure to many other producers. The in built pattern sequencer means you could in theory write a whole track using only this. Though it will export audio if you want to mix elsewhere.

Love it. I don't think anyone will be disappointed by this. A great purchase.

With these apps, you are really spoiling us

I used to own the real MS20 (and MS10 and SQ10) and this app very much takes the place of my old MS20 and SQ10 (especially considering the real SQ10 is only 12 steps, this one is 16!).

It is apps such as this that makes the habitual hunt for modern analogue hardware little more than a futile residual habit — what's the point in real physical synths that take up room and need dusting, when there's this?

Perfect emulation.

If you're a pauper like me and can't afford the real thing, think how lucky you are that you now don't have to. Can't beat being poor. This is seriously good at what if does. Could do with a wider range of sound and more presets, even though you can mangle the bejeezeus out of whatever voice you load. Looks complicated but it's really not.
