The uBASE-QS 2 module is the carrier (or BASE) for four micro modules and explicitly designed for use in the QUICKSWAP CASEs. This carrier module can be plugged into the QS case as any other module; then, the uModules can be plugged in and removed itself into it, even with the AE system running, so you can reconfigure or add needed functions in form of micro modules "on the fly".

A number of sockets provide access to the bus signals, like CV, gate, cotroller, MIDI start / stop / clock.

Included is a small "key" to lift also modules without knobs in an easy way.
