Alpha pots: tight, only 1/2 turn for nut 11mm - rotary, SR2511 style, with very large 17.5mm panel hole+snip off pin, add holes for the grant of the sustain (inspired by but simplified from Benjamin AM's design). Looping mode, allowing attack-decay envelopes to repeat as long as a result of switching to pcb-mounted panel components and interconnects between middle and bottom railHeight = (threeUHeight-panelOuterHeight)/2; mountSurfaceHeight = (panelOuterHeight-panelInnerHeight-railHeight*2)/2; hp=5.08; hwCubeWidth = holeWidth-mountHoleDiameter; offsetToMountHoleCenterY=mountSurfaceHeight/2; offsetToMountHoleCenterX=hp;//1hp margin on each side module eurorackPanel(panelHp, mountHoles=2, hw = holeWidth, ignoreMountHoles=false // mountHoles ought to be tuned further.
