It's a small, powerful synth with the option to add 16 additional oscillators via the app. Some are free and there are plenty of them, some are paid. The possibilities are endless and the sound you can get from it is incredible thanks to the built-in effects. To make working with the synth comfortable, it's a good idea to connect an external keyboard via midi, the ribbon strip is purely intended for previewing the sound and you can't seriously play on it. Perhaps only after starting the arpeginator. I am definitely excited and I was also pleased to be able to assemble it myself. It's just an absolute blast for me and I haven't had so much fun making my own sounds in a long time. It's intuitive, but can be quite complicated with some oscillators. It is also possible to connect this synth via computer to a paid application where you can more conveniently create your own patches and save them to your computer. You will be hard pressed to find a synthesizer at this price.
