That all look modern and not too cold. There is some organic component in it and it doesn't look to 'gamified' like all modern designs are. It is very 'minority report'
All red representation in the attached file are things we can interact with (buttons, bars, faders etc...)
There is an audio representation in the middle that is divided in 4 bands from low to high frequencies. Each band can be boosted with a bar showing the boosted value. (4 bars)
Each band can have a different color type. (4 buttons). This is a multiple option selector.
Each band can be put on S or M mode (little square buttons under the color buttons). This are both on / off buttons.
A big button in the middle can boost everything. A gauge around it should show its boosting activity (it s moving fast around the knob). A big value in the middle is compulsory).
We can also press a Wet only button and a Gang Button. These are both on / off buttons.
The green area is extra audio activity due to the boost applied by the bars.
Another section has filters where we can select the low and high frequencies (showing a value) with a knob or a slider and decide if the filter is Linear or not (on / off button)
Another section has a 'Saturne' treatment.
A Big button, like the one in the middle, showing the gain value, and the activity around the knob.
We can also choose its color with a multiple select button.
A big slider on the left and a big slider on the right are used to set the input and output level. A gauge behind the knob shows the audio activity and level. We should be able to read the value on the fader.
What to avoid
Google or apple super epurated and over simplified designs. We need texture and modern.
