Otari has been one of the primary professional studio multitrack manufacturers. I think the most popular brands are Tascam and Studer; Otari might be third. IS IT DIGITAL, OR ANALOG? 24 track? ALL PRO ENGINEERS SEEM TO DREAM ABOUT ARE 150 channel mixing consoles; they give more thought to the console than to the tape machine or format, it seems to me. Perhaps because that's the thing they interface with the most...they do have several dials and sliders on them, heh heh... HERE'S A BRAND THAT'LL THROW TUBE GUYS FOR A LOOP (just from the name): Solid State Logic. Those, and Neve, are the most salivated over consoles. The more channels, the better to mix that pop single that "translates" well to the "mass audience"...with boomboxes as their "reference" playback device...
