LWG, you're completely right, it probably isn't neccesary to do cut up your synths to the point where they're unrecognizable.
But still I think some people, like me, might enjoy doing these mods and seeing if they can customize or improve the functions of exsisting synths. I also kind of feel that these instruments shouldn't neccesarily be thought of as untouchable works of timelessness.
I feel more endeared to a synth that I've customized in some way, and theres also a kind of satisfaction that comes from actively participating in the design or redesign of a synth to fit one's own needs. I don't have any backgound in electronics, and I've been able add to the functionality of the instruments I use with very simple operations.
So, if there are easily repeatable proceedures for untrained people who might not otherwise consider attempting this sort of thing, I feel it's worth diseminating.

For some reason, I didn't find the link the first time Dr.T, but I'm looking forward to cheching it out now. Thanks again.

Here is a quick example of the easy to do Filter-FM modulation for Moog Prodigies:
http://www.till-kopper.de/Moog_Prodigy_FM_demo.mp3 (721 kB, 128 kbps, mono).
First no FM self oscillating filter.
Then a bit FM applied.
Plenty FM applied and the cut-off moved.
At 0:17 the oscillators are faded in.
0:31 LFO applied to the oscillators. And therefor the oscillator 2 is FM-ed and modulating the filter. This is 3 OP DX like FM

The last seconds are without FM again.

For info: Matthias just posted my next contribution to the collection of mods for the Prodigy; see:

http://www.javaworks.de/page13/page44/p ... age46.html

This one is a switchable range-extension of the LFO frequency.

Hope it's of use!

Thanks T, these mods look very useful and are helping to give me more ideas on some mods I'm planning. This documentation is great.

And another mod for the Prodigy - this time it's a VCA-hold function:

I hope it's of use - but then there's more to come ........

Regards,

Hi T.

I got this mod here too. It was very easy to discover this mod:
just set the DECAY switch somewhat between the on and off position and you got a hold function.
I used this mod for drone notes in my early days of EM 24 years ago.

That is a really interesting remark! I wasn't aware of this possibility ....... which will work only if the mechanical arrangement of the individual switch will allow for it!

I love things like that! These hardware quirks work only with old analog gear .......... this specific example is a bit similar to finding the "in-between" pickup-switch position on old Stratocasters which have the original 3-position switch!

Great input, Till - thanks
