Don’t let that smudge in your screen make you not fall in love with the MNM!
The magic of the MNM is not as immediate as the A4, which is actually kind of cool because the MNM has a totally different type of magic inside!
The machines in the MNM are like nothing else, and it does take time to get used to them to the point where you sort of know which machine makes what type of sound the best. The MNM excels at weird digital sounds and complex pad sounds. You can also load your own wave forms, which can make the MNM sound like something entirely different than how it sounds by default. The A4 sounds lovely, but it will always sound like an A4.
The MNM also has amazing MIDI control. A4 can’t do that.
MNM can do six mono sounds at once, or a six voice poly sound, or split the keys and have a variation of the two. I know A4 has poly now, but it’s only 4 voices of one sound, I believe. The MNM can make some absolutely massive and lush synth pads that the A4 will never be able to make (it’s just different). Great for evolving textures.
I think you have to decide if you want more analogue, or more digital in your setup. The MNM makes a great contrasting element to an analogue heavy setup. Just gonna take some time to get used to it so you can really get the most out of it.
The A4 is like dog who’s in your face and ready to play. The MNM is more like a cat that has it’s own finicky way and unique characteristics.
