The MIDI Mouses stomp-box format features 3 footswitches with smooth-action custom actuators. The Active/Search footswitch alternates between two modes. In Active mode, the 3-digit numerical display remains lit, while the Up and Down footswitches change the patches one at a time to instantly send the information through the MIDI Out port. In Search mode, the numerical display blinks. Using the Up or Down footswitches, you can speed-scroll forward or backward to a desired location without sending any patch change information. Depressing the Active/Search footswitch re-engages the Active mode and instantly sends the new MIDI program number through the MIDI Out port.
