It is commonly known but this 303 clone has a cv and midi sequencer to rival a daw or tablet. You can choose notes and modifiers and generate almost unlimited variations. You can arpeggiate any saved sequence with different directions including random. You can copy small sequences and merge them up to 64 steps. You can expand a short sequence to up to 4 bars then record live transposition into it. The new hammer and mute modifiers actually function as live ways to mess with your gate lengths over midi and cv. This can also be recorded in a longer pattern. Very impressed.
Very easy to use; pretty good sound, build quality is great, and comes with a clear plastic top, and a case which has a space for power supply. Has 12x9 presets loaded, most of which are fairly similar, but I think the idea is you use them as a start point, which you have really as there are no blank slots. There's not enough in it to keep you occupied on it's own, so definitely need to mix it in with other sounds, but that's fine.
