I was lucky to get it on sale. It is amazingly close to the original TB303, I am not missing anything. I believe there is a FM mod for the original, that would be a nice feature to add but that is of course not in the original either. The sequencer works very well. The UI is simple, clean and intuitive. Extra features like the randomizing buttons are very useful to get new ideas. For the price it is amazing. Unlocking it was a bit annoying because it has added a blank space in the front of the copy pasted serial which I noticed only after a couple of tries. There could be more calm, melodic presets like in the roland cloud tb303 vst since 99% are hard acid sequences. But the functions themselves are perfect. No need to spend 10x the money for the high end vst clones or even more for the hardware. Thanks!
