INFORMATION

 
MINIMOOG
Oscillator Input   1/4" jack   CV Chan A   Input is affected by the last note played on the Keyboard
S-Trig Input   Cinch-Jones   S-Trig   See note 1 below
Filter Input   1/4" jack   Aux 1   See note 5 below
Loudness   1/4" Jack   Aux 2    
MOOG PRODIGY
Kbd In/Out   1/4" jack   CV Chan A   Early Models have no CV/GATE Inputs,
however we can fit them.
S-Trig In/Out   1/4" jack   S-Trig   Some Prodigy synths have Cinch Jones connectors.
See note 1 below
VCF In   1/4" jack   Aux 1   See note 5 below
MOOG ROGUE
CV In   Ring of 1/4" jack   CV Chan A   See note 7 below
V-trig In   Ring of 1/4" jack   Gate   Gate works better than s-trig on this synth
MOOG SOURCE
Kbd In/Out   Ring of 1/4" jack   CV Chan A   See note 7 below for connections to ring of stereo jack
S-Trig In/Out   Ring of 1/4" jack   S-Trig   If the level 2 EXT TRIG is off, all external triggers are defeated

Notes

  1. The Cinch-Jones S-Trig connector commonly fitted to MOOG synths, has two flat blades - the narrow blade connects to the tip of a 3.5mm jack plug and the fatter blade connects to the body.

  2. The connection info refers to channel A, but this could equally well be channel B etc. If you are going to use channel B of the converter, you would be using the gate, s-trig, aux 1 & aux 2 outputs (as required) of that channel also.

  3. All the outputs of the PRO-2000/4/SOLO (except the SYNC 24 and MIDI thru) are on 3.5mm jack sockets.

  4. Some of the control inputs on synths are mutually exclusive, ie. you wouldn't use the EXT CLK IN of the SH-101 at the same time as the CV & GATE inputs.

  5. References to FILTER control, mean control of the filter cutoff frequency - sometimes also called filter sweep or VCF frequency control (VCF means voltage controlled filter).

  6. We can fit CV, GATE and FILTER control sockets to most monophonic synths if they do not have them already in most cases

  7. A stereo jack plug has the following connections, tip - ring - and body - in that order. To connect to the ring of the stereo jack involves connecting the body of the 1/4" stereo jack to the body of the 3.5mm jack - and connecting the ring connection of the 1/4" stereo jack to the tip of the 3.5mm jack.

  8. The PRO-2000/4/SOLO (or indeed any MIDI to CV converter) is not generally the appropriate solution for the control of Polyphonic synths. Although a few early poly-synths do have CV & GATE inputs fitted, this only enables you to use one of the voices, so you effectively get a monophonic synth when using CV & GATE. The way to control poly-synths using MIDI is to get an internal retro-fit, which of course KENTON can supply and fit for you.

  9. On the Sequential Pro-One you need to set the centre switch in the MODE section of the Pro-One to the "Repeat/Ext" position to work with an external CV converter.
