I'm talking about the TEENAGE ENGINEERING POCKET OPERATOR series. Design wise, I'm not sure. To me they look like pocket calculators. There 3 to choose from: RHYTHM (PO-12)- A drum synthesizer with a sequencer SUB (PO-14)- Bass Line synthesizer with a sequencer FACTORY (PO-16)- Melody synthesizer with a sequencer & arpeggio I'll be honest I'm really not sure about these. I'm afraid I'm not really impressed. Have you ever tried one of these? If so what do you think?
