I have an early 80's Korg Lambda ES-50 keyboard with a 1/4" Gate output. Can I hook this up to Moogerfoogers?

you can't do much with a gate signal afaik.... CV is what you want. korg uses a different standard for CV/gate signals btw... but it's quite possible to use korg CV in combination with moogerfoogers, albeit not in the correct format (1/5V opposed to the 10V moog signal)

Hi there,

I, too, own and love the ES-50 Lambda from Korg. The Trig Out is more of an S-Trig than a V-Trig (though only 5VDC instead of 10) The gates on Korgs are "closed" when the voltage is high and "open" when the voltage is low.

My Lambda's Trig Out keys the MS-50 that sits on top of it for sound effects. Wish it had a CV output (the Lambda, I mean), yes, but it IS polyphonic, so that would have been difficult to accomplish back then.

Its not that it will not "work" with any Moogerfoogers, it just won't do much that is interesting as you are only toggeling between 5VDC and 0VDC every time you press a key.

HTH,

nodog, you said the moogerfoogers operate on a 10V scale? I've got an MS-20 and I know it operates on a +5/-5 volt scale for most control voltages; do the Moogerfoogers use a +10/-10 or a 10/0 scale?

Don't know who you are responding to but when it comes to GATE signals, many Moog synths used a higher voltage (10VDC) to keep the gate closed.

I don't think anyone said 'foogers work on 10V.

And you are correct about the MS-20 +5/-5VDC, but that is the range for the CV, not the gate (or TRIG, in Korg's case). And the MS-20 is in Hertz-per-Volt, where the Moogs are in octave-per-volt.

Luckily MS-50 accepts both, so I'm set. Anybody know of any other convertor boxes between the two "standards"?

BTW, what tape on whose nose??
