Sputnik Oscillator Pair Day One

Published on Oct 19, 2015 ngarjuna

"A Tale of Two Oscillators:
A really rough and dirty (sorry about the video) exploration of a pair of Sputnik Oscillators.

Simple patch:
SHAPE out from each VCO to a channel of low pass gate (Optomix)
Sputnik 1 FM'ing Sputnik 2
channel 1 opened by Maths 1 triggered by the clock (Silent Way)
channel 2 opened by Maths 4 triggered by Rene (providing the pitch sequence as well)
LFO (Rubicon) giving waveshape modulation and later into CV in
Looping envelope (PEG) into Sputnik 2's CV in
Audio line in, no effects.

So a bad video (again, sorry!) but some delicious sounds. And the wavefolder hasn't even showed up yet..."

Ninstrument SP-12/Drumulator Eurorack Module

Published on Oct 19, 2015 Ninstrument.com

"Do you miss a few of the drum machines from the 80's? Well, even if you don't, how nice is it to get 8 percussion sounds from 10HP?"

via Ninstrument

"Jan over at DSP Synthesizers has created an emulation of the classic SP-12 and Drumulator from E-mu Systems and put it on a single chip. His original project is located here

Seeing this made me long for the older 80’s drum machines and I knew it would also be nice if I could get this into my eurorack using the least amount of space(HP) as possible. Well, getting 8 vintage percussion sounds into 10HP works for me!"
