Novelty drum-tone oscillator

[jojjelito]

Hi all,

I was recently perusing a few old drum oscillator circuits in order to figure out a radical modification to my TR-9090. I came across a good explanation of how the classic twin-T oscillator works at PAIA.

I wanted to make it down with the kids these days, so this variant of the twin-T is now the Teabagging oscillator. By adding a simple comparator that checks the CV level at R3 in the PAIA schematic we can tweak gliss behaviour over time. Thus, when the CV voltage has died sufficiently we can humiliate the circuit by adding fresh voltage through the comparator. This, leads to the drum sound being manipulated in novel and interesting ways.

Schematics might follow at a later date. If you are nice I might even produce tiny PCBs with Ponoko-made boxes for all the cool kids.

Cheers y'all!

Erm, today's date is? :D

I'm sure my revolutionary drum oscillator has evaporated in a cloud of magic smoke by the 2nd of April. However, now that it almost did sound feasible I might axshually make something up later. Sound samples and all... :whistle:

Toodles!

oh maan i'll never forgive you!!!!!!!!1

and i just sold my best friend Stu to the lab next door to be able to afford them

bummer

Mmm, otherwise I know some hungry (traditional) Koreans in case the lab loses interest... He looks yummy enough for some Bulgogi :drool: ! BTW, the kitteh eated my protoboard, oh noes!

Now, after the fun and games with the Core32 and the MB-seq v4 today, which did work on first attempt - yay, it's time for teabagging some noobs in BFBC2 (Schlachtfeld, schlechte Gesellschaft zwei) methinks :ninja:

Happy Easter!

I think drum oscillator will add new tone to drum playing.
