The Gecko is a great solution for quickly switching between programs on midi devices. With an increasing number of guitar pedals being built with midi capabilities, being able to access presets in a quick and efficient manner has become an important part of playing live. The Gecko allows guitarists to use two modes to access programs.
The first mode allows guitarists to scroll through midi programs in a linear fashion. Use the up or down switch to scroll and once a desired program is reached hit the select switch to choose the program. Hold down the up or down switch to quickly scroll through all of the programs from 0-127.
The second mode is preset mode. Preset mode allows you to save 8 presets from 0-127 and scroll through those 8 only. This way you can skip all of the effects you aren't using and be able to play a concert smoothly.
