If you want to play your synthesizer on the go and play no matter where you are, there’s no need to lug around that heavy keyboard. Get one like this. An Italian company called Audioweld created this version that is small enough to be worn on your wrist.
The Synthwatch has a functional seven-key keyboard, which seem a little small for most fingers, but its makers insist have been designed to work with any size finger. The keys allow you to create tunes using a companion app for both Android and iOS. A synthesizer this small needs some software help after all. With the app, you can record, access a sequencer, and a library of 200 sounds. Without the app, it just looks like a toy. However, this toy has a titanium grade 5 case, and costs over $500.
Never fear, it also has watch capabilities with an LCD display to tell the time, a rechargeable battery that recharges via USB-C and a splitter cable that has a 3.5 mm jack for hooking it up to an amp or speaker. The video below doesn’t really show how it works, but there is a video on their Kickstarter page that shows a somewhat clumsy prototype in action.
If you’re convinced you need one, you can pre-order one for about $540 (USD). At that price you have to really love synthesizers or novelty watches to take the plunge, but it is pretty darn cool.
