... For the MG-1 LFO you must feed in the voltage at the connection between R142 (9.1K) and the MOD RATE slider R141 via a 1K resistor, I assume, but I will check it with LTSpice and communicate the result here. I was wrong. The MG-1 - LFO is current driven, not voltage driven like other LFOs (like...

analogmonster - Replacing U12 with a new chip worked! The peak emphasis is now working again! Thanks for your feedback. That's cool 8) So you repaired an original Moog synth, which I consider as great success, as these analog veterans deserve to be kept and "cherished". One thing I have o...

Analogmaster- Thanks for your compliment :wink: but I am just a _monster_ not a _master_ :mrgreen: Thanks for getting back to me. I had no idea about the risks of using a multi meter on the synth. I’ve got a scope I can use from here on out. Ur appraisal of shorting U12 while using the multimeter m...

You can hear it. And you can measure it with a scope at pin 6 of U11.

...and I proceeded to step 5: adjust emphasis trim at pin6 of IC U1012, when I had my multi-meter to check the pins and adjust emphasis trim pot, at some point the oscillation I heard disappeared, and no matter what the trim pots are for emphasis, or filter scale, or filter cutoff, I can no longer ...

... I knew the 907 reduces the audio level and I've never been happy with this. I almost wondered if to incorporate the input and output buffers of the 914 but I don't know if this is worth the effort . But I use the Noise module with LOW and HIGH pass filters and the high pass seems to actually in...

Hello...not sure how to add an audio sample here.... If you find a YouTube video with a good example you can drop the YouTube - link here together with a rough timing information where the relevant part begins. ... I've tried incorporating the Fixed Filter bank in the signal and that does help a gr...

Can you provide a sound example or a link to a sound example?

Hello synth enthusiasts,

here the latest stuff from my modular equipment, fresh out of the elctrical socket... Hope you like it: You

Rudi Linhard?

Yes, that's true. A friend confirmed that yesterday to me.

Thanks

According to the owners manual of the sub phatty the ins and outs on the back side are on line level. Which is just standard. A guitar output signal is just 10 to 60 percent of a line level, afaik. So a guitar amp should amplify more than the factors of line level. Perhaps this is the point the warn...

Does anybody know whether the firmware assembler sources exist and if so who has them?

Yes, that is true. But perhaps the ground RAIL is polluted. This can happen if you have a poor or highly impedanced ground connection in conjunction with a Moog synthesizer. The S-TRIGGER of Moog Synths can cause this for instance, as the the shortening of an envelope gate connector (S-TRIG) to grou...

Which problems? I ask because I don't have any experience with instruments from Behringer.

<LowPriorityComment> I wonder if any brand offers modulation devices (pedals, modwheels) with selectable characteristics. If there is just a linear pot mounted, the characteristic is for linear functional control (or you have an expressive control over your foot :mrgreen: :mrgreen:), where logarithm...
