Duophonic Minimoog

OysterRock · Post by **OysterRock** » Fri Sep 08, 2006 5:39 pm

There is a mini on ebay right now that says it been modified to have the ability to be duophonic (osc1 when 1st key is pressed then osc2 when 2nd key is pressed). Thats pretty sweet. I wonder who did the mod.

Analoguetown, Italy??!!

Nice looking Mini, but who can read that book of a description, particularly in the broken English that is used? (Better than my Italian, however).

Looks more to me like there is a hard and soft sync, and a dedicated LFO with triangle and square wave.

Yeah, he could have at least used paragraphs.

Mono / duophonic mode: yes, true. The first switch (from the left) above the wheel selects the two modes: down= MONO (normal Mini mode – with only one difference: when you want to use the first oscillator alone, in the MIXER section not only setting the OSC2 switch to the OFF position is needed, but also positioning the volume OSC2 potentiometer full counterclockwise!); up= DUAL (duophonic – OSC 2 is routed to a second key you press... like in an ARP Odyssey, but very unusual for a Minimoog!).

Oyster,

First of all, congratulations on having the patience to read through that entire page of gobblygook.

Correct me if I am wrong, but I see no switch as he describes relating to the duophonic mod.

The mod by the pitch and mod wheel is definitely a dedicated LFO (square and triangle wave symbols and a rate knob) and, although it is not completely clear because of it's small size, I am pretty sure that the mod panel at oscillator 1 says "Hard", "Off", and Soft" next to the switches. That would indicate sync to me. Maybe my old eyes are not reading this correctly. I do not see the words "Mono" or "Duo" on those panels.

Any idea what we are looking at in the one picture that appears to be a circuit board?

Oops!! Just noticed a bunch of mainly unmarked toggle switches.....

I have no idea what that supposed to be. The pic is too small. Maybe some of the mods?

I was thinking the mono/duo switch was one of the ones under the "Keyboard Control" switch. Can't read it though. Either that or its one of the unmarked ones on the left.

I have mono, so I have a lot of time on my hands

Mono is nothing to trifle with. Make sure that you are FULLY recovered before you get back at it. People have a tendancy to push at returning to their regular schedules before they are fully over it.

My son had it in high school as a sophomore and he rushed back to play basketball. Even though he was supposed to play short minutes, he was rushed back into full action and his game got worse and worse with every game played as the mono set back in. He had lacrosse season after that and it lingered on for that as well. Even now he still gets very tired if he pushes too hard, and it is 4 years later.

Get over it completely and enjoy the time off reading gobblygook item descriptions on ebay.

Thanks. Yeah, mono really sucks, especially since I have a lot of spinning plates right now.

Oh well, its like a sickly mini-vacation.

It could be worse - you could have duophonic nucleosis!

I used to have second voice kit in one of my minis -- didn't work like that though -- in fact it wasn't really that useable-- I had a little toggle under the glide knob -- it was a tuning nightmare and when you did get it in -(but not for long)- the interval had to be close -under a forth -- a fifth was pushing it. the further apart the notes were the more out of tune it would be, and it didn't trigger a second filter envelope (that was another kit). -so you had hit that sucker just right - I like the idea of the dedicated LFO and some of the other mods are cool features provided they work as expected -- or at all. thats a lot of money for a hacked up mini. the guy will probably have another 500 in getting all the stuff that doesn't work any more taken out
