Marshall DSL100HR midi switch

[Sam SG]

Does anyone know of a single button midi switch that can switch between the two master volumes on the newer Marshall DSL100HR and DSL40CR amps?
I know they make the 6 button switch but I really dont need that. I only use the classic gain crunch channel. I dont use the reverb or fx loop.
But it would be nice to have two masters one goosed a hair for leads.

It really depends on what kind of midi message you need (program change? CC? etc?). There is one here with 2 switches. Look at your Marshall manual and see what kind of messages the master volume switching needs.

According to google master volume is CC #14
I have no idea what any of that means. I have never dealt with midi.
I dont have a manuel for it.
