Four-channel mono summing mixer with master gain.

A simple 4-channel summing mixer: patches four independent audio inputs to a bus where each channel has its own level control, then a master gain shapes the final mixed output. Mental model: stack four signals on top of each other, set each one's volume independently, then turn the master knob to set how loud the whole mix is.

id	cable	what it does
`in1`	audio	Audio input for channel 1; its level is set by the Ch1 fader. audio signal
`in2`	audio	Audio input for channel 2; its level is set by the Ch2 fader. audio signal
`in3`	audio	Audio input for channel 3; its level is set by the Ch3 fader. audio signal
`in4`	audio	Audio input for channel 4; its level is set by the Ch4 fader. audio signal

outputs

id	cable	what it does
`audio`	audio	The mixed bus: the sum of all four channels (each scaled by its level fader) attenuated by the master gain. Goes silent when all four channels are at 0 or master is at 0. audio signal

controls

control	what it does
Ch1	Channel 1 level — how loud or quiet channel 1 is in the mix, from mute (0) to full (1).
Ch2	Channel 2 level — how loud or quiet channel 2 is in the mix, from mute (0) to full (1).
Ch3	Channel 3 level — how loud or quiet channel 3 is in the mix, from mute (0) to full (1).
Ch4	Channel 4 level — how loud or quiet channel 4 is in the mix, from mute (0) to full (1).
Master	Master gain on the mixed bus — scales the whole summed signal from silence (0) to unity (1). Turning it down fades all four channels together without changing their relative balance.
