"Very rare and sought-after Moog accessory, rarely used, just checked out by Switched On Austin, fully functional, in very good cosmetic condition.

These are getting hard to find. Includes copy of promo page and service manual with schematics.

In 1973 Moog Music put on the market various accessories to be attached to the Minimoog model D and also to their Modular models (they released the Moog modular 15, 35 and 55 in the same year): the 1130 Percussion Controller, the 1121 footswitch, the 1120 foot controller, the famous 1150 Ribbon Controller and the 1125 Sample and hold unit. Nowadays it is very difficult to find one of these equipments, even though they are only accessories (only work when attached to the Moog synthesizers, such as the Minimoog, the Sonic Six, etc.).

The Moog 1125 Sample and Hold Accessory Controller is a device that captures the voltage range of the synthesizer, creates a pattern and repeats it constantly. The waveform (sawtooth or random) of this pattern is controlled by a slider on the left side of the 1125 -the other two sliders are a glide and the scale control. Two knobs in the center of the equipment, one for speed (rate) and other for the sample pattern are located above three on/off switches: one to record and the other two to start and stop the sample (a red light indicates when it is working). Five switches on the right side complete the unit: one to control the extent of sampling, two on/off switches controls the outputs of the instrument, an on/off switch controls the trigger and another controls the size (short or long duration) of the gate.

The Moog S&H does not generate sound on its own, it is designed to control specific vintage Moog synthesizers with the Cinch Jones Accessory Port --- Minimoog Model D, Micromoog, Multimoog, Polymoog, Sonic Six, and I believe the Moog Modular as well. This unit comes complete with the Moog accessory pigtail cable so it is ready for use out of the box (just add synthesizer). Also includes a copy of the Moog Accessories Service Manual.

Complete with all connectors, there are just four plugs to hook up, and you can be up and running in a jiffy. There is a 6-pin Jones plug for power (from the Minimoog, Sonic Six, etc.), an S-Trig plug and two jack plugs to trigger oscillator pitch and filter (or volume).

It generates random or sawtooth samples or a combination of both, varied by slider. Scale and glide are varied in a similar way. There is a wide/narrow scale span switch, variable rate (speed) and pattern rotary controls, separate output switches and short/long trigger switch."

This particular Sample & Hold controller was made on 10/21/1975, and is serial number 2642."
