The Gecko is a compact, lightweight solution for quickly switching between programs on MIDI devices. With an increasing number of guitar pedals being built with MIDI capabilities, having the ability to access presets in a quick and efficient manner has become an important part of playing live. The Gecko MKIII gives guitarists three modes to access programs. Features: Lightweight, compact MIDI controller PC signals of 16 MIDI channels can be sent simultaneously 20 presets Tap tempo control for multiple devices Can be powered by battery or 9V DC external power supply Two DC outs can also supply power (when using external power supply) Three Modes: Select Preset Mode (E1) — MIDI signals sent only when the OK footswitch is pressed Instant Preset Mode (E2) — MIDI signals sent as soon as the preset number is changed Direct Mode (E3) — MIDI signals sent as soon as the program number (0-199) is changed Gecko MKIII has 20 presets. Each preset can store one PC (program change) message for each of 16 MIDI channels. In modes E1 and E2, you can edit presets. PC # can be set between 0 to 199. Also, if set to OFF, no MIDI signal will be sent to that MIDI channel. Each individual MIDI channel can be turned off globally. Since MIDI channels that are set to OFF globally are not displayed during preset editing, setup can be shortened. Also, for each MIDI channel, you can set the CC number to send when pressing the OK/TAP footswitch and use it as tap tempo control. Since you can set individual CC numbers for each channel, you can control tap tempo of up to 16 devices at once.
