I’m working on designing a gate in circuit for a modified version of the ciat-lonbarde gerassic organ paper circuit I’m trying to design and build.
basically, it’s the marbles gate-in circuit, combined with a momentary button that it is xor’d with. I am using a pot to act as a variable resistor, which seems to set a threshold for the gate in. I updated the resistor from the marbles schematic that pulls down +V from 100k to 220k because it seemed to allow more of the full range of the threshold pot. the simulator doesn’t show it, but It goes from pretty much a 0v to ~10v threshold, so you can effectively mute or “always on” the gate (both with a gate signal in and with nothing patched in).
from the output of the xor, when the button is low I get nice crisp edges on my scope:
when the button is high, they are much more “fuzzy”…it seems to go haywire for a second when it’s going between low and high:
Do you know what might be the cause of this weirdness?
(Also, I haven’t been able to get the LED to work yet…still trying to figure that out.)
