The tight Erica Synths Pico System III stacks up a set of pre-configured Pico modules in one control panel, laying out a forest of patch gates for unlimited sound-tweaking, and on the side, you get a blue voice-card slot. Just like the computer cartridges or keyboard style cards from back in the day, this humble slot is provided so you can load a complete sound onto a card and slot it in at just the right moment - maybe even between songs during a live set. A deck of ten cards comes included: five pre-loaded with factory sounds and five that have been left empty and ready for your own custom sounds. Basically, this setup removes the leg-work involved in re-routing the architecture every time you want to switch up the sound so you don't have to keep your bandmates waiting.
