16 Channel Audio Loop Switcher
This is a 16 channel audio loop switcher with 16 inputs and 16 outputs.
Analog signals within a +/- 5V swing can be used, such as 9V guitar effects (+/- 4.5v)
Signal paths can be re-configured on the fly via serial commands that arrive over RS485, such as with this foot switch controller project https://www.pcbway.com/project/shareproject/16_Switches_to_RS485_Output_Commands_31683848.html
The sketch in the ESP8266 can be customized to wait for a certain foot switch to be pressed (by recognizing a certain RS485 serial command) and then change the signal chain. For example
Switch 1: Connect Guitar to Amp
Switch 2: Connect Guitar to Effect 1, then to Effect 2, then to amp
The signal chain can be completely controlled, including changing the order of effects, for example
Switch 1: Guitar to Effect 1, then to Effect 2, then to amp
Switch 2: Guitar to Effect 2, then to Effect 1, then to amp
Note: The prototype assembly used small screw terminals for RS485 connections but the parts list here uses 0.1 inch Dupont style headers.
