.PSD... Otherwise, have at it!
Optional slogan: "Mix freely"
I've attached a screen shot of the main control screen. This is literally a virtual sound board, it's designed to control motorized sliders on digital sound boards. As such, some iconery based on the LS9-32, M7CL, PM5D... or any mixer at all (digital or analog) might work.
The color scheme is a bit flexible but in live sound, you see lots of dark dark gray backgrounds (approx #333333), and whites, with sprinkles of bold color. I will probably steer the website design and/or even the final software colors to match YOUR logo... but the screenshot is a good start. Something that looks good on both a dark and white background (for print) would be ideal.
This product is a utility designed to do a job, it's not just eye candy... but a little silly/cartoony/edgy is not a bad thing. Think Flying Toaster. The product can be used wirelessly around a venue and is all about freeing the user from the traditional interface... like mixing on air. AirFader.
And seriously - thank you in advance to everyone who participates, I will do my best to give constructive feedback for your efforts.
