<BR>houses tend to prefer 3U :-) (they're more compact). One advantage
<BR>of the 3U format is that it's a standard in the industry (at least
<BR>in Europe) and therefore racks are easy to find and relatively
<BR>inexpensive.

<BR>While the whole matter of ergonomics and panel layout is a matter of personal preference, I can share an interesting aspect I've found with the Blacet-type layout. With the knobs lined up and fairly close together, you can easily play several knobs at the same time with one hand. For example, using my right hand, I put my thumb on the left side of a knob, and my other fingers on the right side of other knobs. With practice, you can smoothly fade things in and out while varying LFO rate or filter frequency or controlling regeneration or whatever and still have your other hand to work with. If you focus on moving your whole hand up and down, the knob under your thumb goes in the opposite direction of the knobs under your fingers. If you rotate your hand, the knobs all go in the same direction. Where you place your fingers in the first place (near a fingertip or near a knuckle to start) helps control the extent of knob rotation.
