Vintage Synth Scans via Tim Stinchcombe

ARP 2500 pictured. You can find the full size scan for this and more at Tim Stinchcombe's site. You'll find Moog and EMS as well.

Update via alt-mode on AH who owned and sold a 2500: "The modules are labeled so you know which column corresponds to the input/output. Yes, there is a small gap between the module and the matrix but it usually isn't a problem, provide you don't need to get out your bifocals (more on that later). There also tends to be similarity between modules and the inputs used. Most of the oscillators have VC inputs on columns 1, 2, & 3 in the upper matrix. There is also a color-coding scheme for the slider caps that, if you have the right caps on the sliders for your modules, helps make things clearer but you need to move the caps around anytime you rearrange modules and some of the colors are impossible to find these days.

The upper matrix tends to be for keyboard CV and Gate signals and you are correct that the jacks on either side allow access to a particular row of the matrix so you can patch between the upper and lower matrices as well as external gear.

Each row is like a giant multiple. You can send one output to many inputs from the same row. You also need to dedicate a row or two of the lower matrix to audio outputs.

To patch between modules, you select the column of your output on the module, slide the matrix lever for that column down to an unused row and slide the matrix lever for the input of the destination module to the same row. So, in some sense you are limited to 20 "patch cords" in the lower matrix.

The middle few rows of each matrix are not connected to anything so it is the place where you leave disconnected inputs and outputs until you need them.

The fun of a 2500 is that you can have lots of "happy accidents" as you move the sliders since you can end up influencing other modules or finding unintended modulation sources. The downside is that you can get some crosstalk between the rows of the matrix but I never had too much of a problem with that.

My frustration with the 2500 was that I had to squint a lot (or find my glasses) to line things up on the matrix. It depends on how you have the synth set up but you really want those matrix switches nearly level with your eyes so you can see exactly which row you are using."

Rare Polyfusion Modular - Moog Format

Formant Filter

"The serial number on this module is 7505.

The Variable Formant Filter has 3 bands of variable width, frequency, and level for sculpting sounds. The module works great and has seen light use over the past 6 years in a smoke-free home studio.

This module was originally housed in a wooden box with a simple power supply. I had Synthesis Technology MOTM power connectors added for use in my system but it can easily be switched for any +/-15V supply.

These modules were part of Martin Newcomb's Museum of Synthesizer Technology in the 1990s. They are shown on page 78 of his wonderful book on the museum and can be seen in the following You-Tube video at around 2:00. This is an opportunity to own a truly unique part of synthesizer history!" [see this post for the video. see Part 1]

Dual Ring Modulator

"This is an extremely rare Polyfusion Modular Dual Ring Modulator module from 1975. When Polyfusion started, they made these modules to fit into a Moog modular system before they had developed their own format. This module, along with the other ones I'm auctioning off, are likely the only modules of this type known to exist! The serial number on this module is 7503.

The Ring Modulator consists of two circuits that multiply the X and Y inputs together, producing a tone that is the sum and difference of the two inputs. The module works great and has seen light use over the past 6 years in a smoke-free home studio.

Dual Sample-Hold

"The serial number on this module is 7506.

The Dual Sample-Hold consists of two sample & hold circuits that will retain the incoming voltage whenever the manual trigger button is pushed or the clock input goes high. Along with the sampled output voltage, the module outputs a Moog S-Trigger signal making it a quick V-trig to S-trig converter. The scale knob sets the range of the output with respect to the signal input. The module works great and has seen light use over the past 6 years in a smoke-free home studio."

Using Percussa's Audio Cubes and MIDIBridge

"If you have a hardware MIDI interface and external hardware synths, you can send the MIDI data from MIDIBridge to your external gear, or receive MIDI data from your external gear and use it to control the cubes’ colours. For example, you could use an Elektron Machinedrum, and control its patterns using the AudioCubes, as well as its effects, and at the same time receive the MIDI clock from the machinedrum and use it to control the colours of the cubes, for example to display the beat using a flash of red light. If you happen to play in a band other people can visually sync to the colour pattern. In MIDIBridge, you can select per cube a MIDI input and output port, so you could use one cube with a hardware synth while using another with software on your computer through a virtual MIDI port."

MetaSynth 5

"Many people consider the Image Synth to be the heart of MetaSynth. The presentations on this page will introduce you to Image Synth "Basics" as well as demonstrate some of the extraordinary sounds that the Image Synth makes possible.

The Image Synth is a composition and sound design environment where you paint music and sound.It is not a soft-synth or synth plug-in."

Moogist Talks - What Can You Do With 1 Note?

YouTube via timtsang3. via twitter.com/TaraBusch
"What can you do with a single note/sound? Besides its legendary tone, the Moog Synthesizer is known for its monophonic nature - the ability to produce only 1 note at a time. Therefore, the goal of The Moogist is to "think outside the box" with this certain limitation - whatever it takes - to make beautiful music with this amazing machine/instrument.
