When you set the tempo on the 'Master' device, it generates a PO-Sync signal at the same relative speed. This can also be generated by other external devices (we’ll cover this later). In simple terms, a ‘Master’ Pocket Operator will generate a PO-Sync signal using its own internal clock.
Where does this PO-Sync signal come from? It’s a similar method used in old school sequencers or modular equipment where you might see it labelled as ‘clock’ or ‘trigger’ output. The time interval between each pulse determines the tempo at which the Pocket Operator plays. This signal is made up of electronic pulses with evenly spaced time intervals. Rather than MIDI or USB Sync that we’re used to seeing on electronic instruments, Pocket Operators use a trigger based control voltage signal called PO-Sync. What protocol do Pocket Operators use to stay in sync?
Before we start connecting Pocket Operators together for a synced-up jam session, let's answer some fundamental questions on how it all works:
