Manual mode allows guitarists to scroll through midi programs one by one. Use the up or down switch to scroll through programs 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.
With the amount of digital effects being used in live situations growing and growing, One Control responded to the need to have easy access to your favorite presets in an extremely quick and easy manner. The Gecko not only allows to you scroll through eight user defined presets but also allows you to scroll from 0 to 127. For guitarists who use rack effects that have complex controls, they know that using them in a live situation is quite difficult. With the Gecko you can be at ease knowing that you can use your favorite rack based effects and not have to worry about having a tech scroll through presets for you even worse, having to go back to your rack between songs and change a preset yourself.
