Front page synthesizer trial: four kinds of group module with long faders

In the synth canvas trial for website admins, a group's plane is one of four modules in turn: a mixer, a routing matrix with a button at each crossing of inputs and outputs, a modulation controller with rate, depth, wave and CV outputs, and a filter with cut, resonance, drive and a response display. Each is two or three printed sections with a header and rule, and the first grows to the band's height, so a tall band has long faders. Fader tracks are recessed slots with calibration ticks on both sides at a fixed spacing, a 10 to 0 scale beside the first, and wider caps. Legends are printed at a size that reads. Short bands drop the lower sections. Nothing else on the page changes, and nothing changes for anyone else.
