Have you been wondering if it is possible to create musical patterns from a portable, inexpensive device you can always use on the go? Enter the pocket operator. What exactly is a pocket operator and how do they work? Read on to find out more.

What Is A Pocket Operator

Pocket operators are tiny battery-powered sound modules, ultra portable music devices,with studio quality sound and the flexibility to make music on the go. They are affordable for everyone and compatible with all other music gear. 

There are different symbols and numbers on the keypad, which makes me think of a calculator, but then once you have an idea of what every one of them does – maybe watch some videos online – then it becomes highly addictive and you won’t be able to stop making music. 

Being able to create 16 beat musical patterns, and then string those together into longer sequences to make songs is undoubtedly an ingenious invention. 

Sync Pocket Operators

The unique feature of these little sound modules is that you can sync pocket operators together and to other external devices, but you do not have to use a USB. Pocket Operators use a trigger based control voltage signal called PO-Sync. This signal is made up of electronic pulses with evenly spaced time intervals. The time interval between each pulse determines the tempo at which the Pocket Operator plays. 

A ‘Master’ Pocket Operator will generate a PO-Sync signal using its own internal clock. This can also be generated by other external devices. When you set the tempo on the ‘Master’ device, it generates a PO-Sync signal at the same relative speed.

The ‘Master’ Pocket Operator outputs PO-Sync signal, and a ‘Sync’ Pocket Operator will receive it. The pulses from the signal trigger the ‘Sync’ so it runs at the same tempo as the ‘Master’.

There are two 3.5mm stereo jack sockets on the back and then A ‘Master’ will output PO-Sync through the output, and the ‘Sync’ will receive it through its input. Then all you need is a regular stereo 3.5mm jack to jack cable (aka Aux Cable). Teenage Engineering – we will come back to them later – have created some smaller in length cables to use and you can buy them from Amazon. A pack of 3 for £15.00, so a bargain. 

Types of Models

There are three types of models that you will typically find for pocket operators, which are mainly used for generating electronic music and favorable for those just starting out. 

  • The Rhythm model is a drum machine. 
  • The Arcade model has classic video game sounds
  • The Sub model gives you bass notes and so on.

There are pocket operator cases to go with them if you feel like you need one, but they can be used without just as well. The computer-1 is a pc case made for all your needs, taking up little desk space, made of lightweight aluminum, with chrome handles. It comes in a range of 5 different colors. It fits a dual slot graphics card up to 180mm and costs £195. 

Pocket operators can become quite addictive as they do not need much to get you started, and you may spend hours on the device. Of course that is what they want you to do. 

There is the option to delete everything you have created in one session or over the whole day if you are not happy with the sound. The pocket operators can be connected to an external speaker or a laptop so you can get the full experience of listening to your work or save it for later.
