I'm very new to synth/ chip tunes. Bought few bits recently including a couple of other Pocket Operators & it was the Pocket Operators I've enjoyed using the most. Picked up a Sub to add to the others I had (Rhythm & Robot) & the Sub is by far the most creative of the 3 I now own. The pre set patterns are funky & you can do a lot with them thanks to the creative effects like the high/ low sweep & the ability to raise or lower an octave, or shift up half a step is invaluable.
