Thank you Scott, that all made perfect sense! I appreciate you putting up with my partial understanding of some things. The reason I asked about the pot is that I'm stuffing the mod into the Monotron, so of course anything that I can leave out is helpful. It seems clear to me that the additional pot...

https://www.muffwiggler.com/forum/userpix/4061_monotron_extgate_1.jpg Hi Scott! So, I'm modding a few more Monotrons and I think I'm interested in utilizing your new gate/pitch fix method you've outlined. My previous method of using a switch on r11 worked very well, but I'd like to avoid the additi...

Thank you teatanic, Scott & th0mas, for your help! I really appreciate it! I've got it all worked out now, and finished two Monotrons this morning! It turns out one of my original connections was not solid enough in my resistor replacement circuit, so once I got that worked out the switch worked gre...

Hi Oran. My best guess is that R11 is removed and there is not yet any other connection to IC2 pin 10 (the gate input/test-point). This LM324 has a PNP input stage and base current could cause this floating node to rise, which turns on the Monotron gate signal. Then playing the ribbon would sort-of...

Hi all! Long time lurker, first time poster. I wish I had something to contribute for my first post, but I come to you with a problem instead. (Disclaimer: Though I'm pretty good at soldering and such, I'm only learning how to read schematics.) I'm currently adding CV inputs to a Monotron for a frie...
