Quoted from Markharris2000:
I have never actually played a machine with Pinsound, but as I understand it, its far more than just new speakers or amplifiers. My understanding, Pinsound taps into the same logic control that on older machines triggered/generated their sampled original audio (music, sounds and voice) clips and played mono boring audio, and instead actually uses those same triggers to generate a whole new sound track entirely. And the Pinsound sound package can be modified at will (and they have a library of user's contributed custom sountracks) to be used depending on your mood. In this way, the machine 'thinks' its still pumping out the old school sound, but in reality the entire Pinsound audio system is working in parrallel with a whole new audio track, hifi sound...
Am I correct?
I'd say that's an accurate description. Personally, I've created about 20 custom PinSound orchestrations for a multitude of titles, and about a half dozen shaker routines that PinSound includes with their shaker. The shaker is awesome for a few reasons: 1) you can add a shaker to any pin that supports PinSound, 2) you can program shaker events on a per audio event basis, 3) you have 9 preset shaker actions and 3 custom actions you can variably assign (e.g. start intensity, duration, end intensity), and 4) it has a built in relay that you can connect an external powered device to (e.g. fog machine, lights, etc.) and assign actions per sound event (e.g. duration, # loops, time between loops).
I could go on and on about their products. Both my Getaway and my recently sold DE JP had PinSound boards, speakers, headphones stations - external volume control, and my Getaway has their DMD power board in it.
