Circuit Abbey – Gravity Well demonstration
Here’s a nice video featuring the gravity well, background data below:
The gravity well uses cv to shape audio.
Where a filter removes certain harmonics the Gravity Well modulates
the existing waveform to create new sounds.
I’m using a doepfer A110 VCO (sequenced with a Modcam touch sequencer)
Square & sine waves are fed into a A114 ring modulator. Its output goes into the
Gravity Well.
The Gravity Well has 4 CV inputs.
I’m feeding a sine wave LFO into the first input (called latitude)
Into the second input (called Longitude) I later (1m,55 secs) feed a random CV.
This was generated using a combination of a noise generator, a sample/hold & a comparator.
A 4MS Noise Swash, Buchla 265 (Source of uncertainity) or the MakeNoise Wogglebug
would also prob work well as random sources of control voltages.
Modules used:
Circuit Abbey Gravity Well
Doepfer A110 VCO
Doepfer A114 Ring Mod
Modcan Touch Sequencer
Doepfer A118 Noise Gen
Doepfer A148 Sample/H
Circuit Abbey TripFire (Comparator)
Many thanks to Matt from Rhythm Active for supplying the Modcan Sequencer, The Circuit Abbey Gravity Well and Tripfire
