I went through the same dilemma several months ago - MnM, or A4?

While I don’t own an A4, I do a Monomachine and a Machinedrum. I bought my MnM about four months ago and haven’t so much as booted up a DAW since. It also inspired me to buy the MD which is great (very great) but the MnM is something else entirely. It is sooooo deep it will take you months if not years to completely master everything it can do. The learning curve is steep, but once you’ve got a grip on it, it’s like having a Super Weapon in your studio!

A couple of things that made me go with the MnM instead of the A4 was the fact that the MnM has 6 tracks, unique internal sound machines, an internal drum machine (though very simple, it can be tweaked beyond recognition and it is boss for making glitchy textures), and also the awesome FX chaining/processing on the MnM that gives it the ability to act as an effects unit for external gear, or extreme sound mangling.

I agree with Xmit. This is my all time favourite “desert island” synth. Endless fun. And like Steevyhead said, once you get one box, you’ll be hooked and want them all!

Sorry for the long post. I just know how hard it is to decide. Truth be told, I doubt you would regret going with either machine. But the Mononmachine is probably the most unique.
