"Gig Board" is a guitar pedal effector board. **Important: To connect this app with a guitar, you need "4-pole 3.5mm headset cable". - 4-pole 3.5mm adapter has two kinds of standards : CTIA / OMTP (Please refer to the illustrations above.) - You have to find out what standard your device is. (Most Android phones use CTIA.) - If you unplug headset cable, app is totally muted. - At first launch, it may not sound or has latency, so please relaunch the app several times, or unplug the cable and re-flip it. - You can adjust latency by selecting buffer size. (Click right bottom button to open option menu) - The smaller buffer size, the lower latency, but it causes audio glitches.
