drum 1


mms

"pulled my moms powershot out of the drawer, taped it to a pole and threw this box under the hot lights. XOR percussion circuit as a gift for a friend, nothing fancy:

2 pairs of schmitt triggers oscillators each into their own 4070 XOR gate, output of those into a third gate. Simple line level decay vca ala Elliot Williams hackaday series. Second buffered output straight outta the 3rd xor gate before the vca, hot and loud for something close to modular level? The oscillators at highest frequency setting "die out" and effectively fall out of the mix. 9v battery. Moisturized my hands right after recording."
