So Awesome is this little box!

Not sure why the orange color is 30 bucks more that all the other colors but whatever, I wanted orange so I could swap keys with a black one and have two that go with the SMK37 Elite. Almost pulled it off but was sent a white body and black keys,l model, different seller than here. Might still look cool but the real thing with this box, regardless the color, is what it can DO! OMG!!! what do you want it to do? Open source firmware has lit the synth mod community on FIRE! There are over 100 firmwares to try now. Some super Gems for sure, and they flash fast right off your phone or tablet, pc, laptop, it is beyond what I was hoping for. Absolutly grab 1, even the stock firmware is fun. For such a small size the processor and wee bit of ram do a brilliant job. At this price point it is silly not to grab a couple. The FM 1 is pure FUN. Right now I am running and testing a great firmware beta version, vibe coded by a fellow synth nerd, a fork of the original firmware. I am blown away at what any old average Joe or Jane can now do coding wise. This box is the future...bye bye pricey elektron type devices, I be hoppin on the Vave Wave! Check out the pocket amp with speaker box combo to set up a portable music mini go bag. Completely satisfied!
