my device seems to have an issue when using clock or low frequency notes. The original clock is also present in the output signal as well as the division. Like a sort of distortion alternating with the main output. Any idea ...

Advanced Sync for the VC Master Clock https://electro-music.com/forum/viewtopic.php?p=449211#449211 Hi all,

i was trying to get a sync setup working on the Fonitronik VC Clock.

When the Saw wave gets down to 0V the comparator IC1B triggers the discharge of C2 so i thought that would be an easy way to mod the schematic. Just by shorting Pin 5 ...

QFG anomaly https://electro-music.com/forum/viewtopic.php?p=442271#442271 Hi folks: I built this awhile back, but have observed a weird but interesting anomaly with the 90 degree LED as follows: it shines brighter than the rest and 'overlaps' with its 0 and 270 counterparts. Sonically, this affects the CV so that it appears ... mybud Mon, 28 Oct 2019 09:45:20 -0700 fonitronik Thomas Henry x4046 VCO mods https://electro-music.com/forum/viewtopic.php?p=442083#442083 Additional photos for the TH x4046 VCO mods. ixtern Mon, 14 Oct 2019 01:49:17 -0700 fonitronik Thomas Henry VCO Maximus mods part 1 https://electro-music.com/forum/viewtopic.php?p=440497#440497 Many thanks for this, very interesting and helpful.
You are welcome.
Must to mention that some of the add-on modules (trim pitch, ref voltages) I have soldered to the board finally - connectors were not very reliable.

But one could use the J175, however, it has a different footprint which makes the mounting a little bit fiddly.

here is a picture that shows the different pin-out and how it corresponds to the PCB:

555 VCO not sounding https://electro-music.com/forum/viewtopic.php?p=437915#437915 Hawk eyes, no doubth.

Yeah, I forgot to put the tempco. I found it and solder it some days after posting this thread, but I forgot to say it. The OSC is working nicely since then.

Thank you so much for taking the time to sherlock holms it ;)

3rd run for Thomas Henry's 555-VCO and Controller LFO https://electro-music.com/forum/viewtopic.php?p=436418#436418 it's okay.
but you could also use just one of your 1k and change the other values from 100k to 49.99k.
or just buy the correct one from thonk.

That´s perfect. I´ll go for the 49.99k. Danke!

Thank you for some great designs. I learn a lot!
I'm an electronics newbie, so please explain how the output opamps work in this circuit. Are they used as differential amps? How do they mix the dry and wet signals.
