Re the linked advert with the line "every nun needs a Synthi": my secondary school had a Synthi A in the music dept, and there was a poster on the wall of the music room reading "Even Orpheus needs a Synthi". This was in September 1976. Possibly there were other variants? -- Redrose64 ( talk) 22:46, 9 August 2009 (UTC)
There were three types of patch pins: white, red and green. The proportions differed: I think that about 75% were white, the rest red or green in equal quantities. Each was essentially a jack plug, no larger than 2.5mm diameter - but may have been smaller, since they were easily bent, particularly near the tips. Red and green ones contained a resistor, whilst white ones were plain wire internally.
I was once told the circumstances for using each, something to do with "if you're routing the signal out of here or into here you should use a red pin, otherwise use white", but I was never told the actual reasoning, nor did I see an official description. Didn't find out what green were for, either. RTFM yes, I would have done, but I was under the instruction of one who believed in hands-on training, and I think the manual got filed under "recycling". -- Redrose64 ( talk) 10:46, 11 August 2009 (UTC)
I'm not aware of any patch pins, white or otherwise, that were a straight short-circuit inside. this would have made their delicate construction rather redundant, & in any case, the purpose of the resistors was to remove the need for the extra circuitry that would have been required to buffer multiple destinations from a single source, whether this be signal or control; if you patched using multiple "short circuit" pins, the sources would be overloaded.
my synthi has white, red, green, yellow & two shades of grey. I mix & match them with impunity, but will measure the resistances at least & report back.
& upon the matter of tolerance- in 1970, very accurate resistors of the small size necessary to fit inside the patch pin shells were expensive. remember that the EMS instruments were an attempt to make synthesis more affordable; it made sense for the pins to be offered in standard & deluxe variants. the higher accuracy of the more expensive pins has a practical advantage if one wishes to achieve a predictable & reliable result. one wonders what accuracy of component was installed in the prestopatch devices....

[reporting back, after an unconscionable absence, for which many apologies...]
white- 2k7 red- 2k7 yellow- 2k7 grey- 2k7 purple- 3k1 green- 6k2
I can only presume- not wishing to take them apart, & with no way of measuring it- that the difference between the various 2k7 pins is the accuracy/tolerance of the value. plainly, though, there are no straight shorts amongst them.

I will try to correct some spelling, grammar and syntax errors. However, there are a few points where I don't exactly understand what one of the previous contributor meant. More on that later. SentientContrarian ( talk) 07:36, 1 April 2012 (UTC)
