The Moog 15 was the smallest of the "second-wave" pre-packaged Moog modular systems - the others were the Synthesizer 35 (bigger) and the Synthesizer 55 (biggest). The 15 was packaged in a "P" case (same as the older "first-wave" pre-packaged systems with the "p" suffix, "p" for portable. The 35 and 55 were in "c" cabinets, which probably stood for "console" (Kevin???). The "p" case is 18"W x 25"H x 9.5" D, covered in black tolex, with a removeable front cover plate and a rubber-covered handle on top. The 15 has: (1) 921A Oscillator Driver (2) 921B VCO (1) 923 Random Noise/Filter (1) 921 VCO (2) 911 Envelope Generator (2) 902 VCA (1) 904A VC Lowpass Filter (1) 907A Fixed Filter Bank (optional, added cost) (1) 995 Atenuators Panel (1) 4-input Mixer with Multiples (1) Reversible Attenuator (1) CV/Trigger Output Panel The last three items were not standard Moog modules, they are specific to the 15 (the bottom row, below the VCO's). Inside is a power supply. The Model 15A was the same system without the 907A Fixed Filter Bank. The 15 came with a 4-octave duophonic keyboard (Model 952). The 35 and 55 used the standard 951 5-octave monophonic keyboard. The 15 does not have the CV routing panels and the S-Trig/911/902 routing panels that the 35 and 55 have - too bad because these controls are great for live performance. Not enough room. It's pretty easy to emulate a Minimoog with a 15, but there's some big differences in sonic potential due to the fact that the 15 has more stuff like: * Sync on the 921 * Linear FM on the 921B's * Seperate Decay and Release on the 911's * Inverting capabilites for upside-down envelopes etc. * Sine waves * Pulse Width Modulation * Lin/Exp VCA's with (+) and (-) inputs * Two additional EQ-type filters, low- and high-pass * The fixed filter bank with real (heavy) inductors in it * Waveform clamping on the 921 (for LFO sync etc.) And of course a big bunch of patch cords that you can plug all over the place. All in all however not a whole heck of a lot more useful than a Minimoog, having what I would consider the bare minimum number of modules. But it is totally patchable and when grouped together with a few other patchable analogs you can really go crazy with the patchcords. I would spend $1000 for one in good shape, $500 for a busted one, and for a mint machine maybe $1500. Two grand if it's still in the box. - Gene gstopp@fibermux.com Subject: Moog System 15 Author: TIMOTHY GUEGUEN at ccrelayout Date: 4/4/96 4:15 PM Since I'm sitting here anyways, I figured its about time I posted this question. Is anyone out there familiar with the Moog System 15? I may be wrong, but from what I read it seems to basically be a patchable minimoog with a duophonic keyboard. And what is one worth these days? If I ever get my hands on a modular Moog, its probably going to be one of these, much as I'd love to buy a System 55 or similar. As a bit of trivia, "name" users of the '15 included Larry Fast and Yellow Magic Orchestra. tim gueguen ad058@sfn.saskatoon.sk.ca
