Source Audio's One Series pedals can be run in stereo and mono, and share a number of features. With 128 onboard preset slots, these digital stompboxes are hugely powerful, and when used with the Neuro graphical editing and librarian software – a mobile app for all iOS and Android devices (cabled connection) and a desktop version for Mac and Windows – you are offered comprehensive control of the effect.

Here we are going to look at the C4 Synth Pedal. Like the others in the series – such as the Source Audio EQ2 Programmable EQ – there's a Control Input jack for the Source Audio Dual Expression Pedal and a USB port. You'll want that editing software close at hand to allow you to adjust editing parameters, stereo routing options and advanced EQ control, and of course to manage your presets.
