Description

The Bristol Bloodhound MKII is a 20HP dual oscillator with a built in VCA, wave multiplier and a unique feedback circuit. The voltage controlled oscillators are capable of going from clean to very noisy and have been designed to be a characterful and gritty VCOs that can also solidly track 1v per octave and fulfil more traditional musical duties as well as sonically tearing things up! This MKII version also features dedicated square wave outputs unaffected by the VCA.

The sine core is an interpretation of the sine oscillator found in the Dreadbox Antiphon (used with permission) using a 2164 for both generating the sine wave as well as the VCA portion of the module. A switch for each channel will pull the oscillators down deep to serve additionally as an LFO.

The wave multiply section is derived from the CGS module of the same name (also used with kind permission from Ken Stone) with only minor adjustments – most notably a feedback section for creating harsher dynamics and noise. The sine oscillator is normalised to the wave multiplier via the Wave in jack. The second oscillator’s sine output is normalised to the CV in of the wave multiplier and vice versa.

Inputting an external signal into the Wave in breaks the sine connection but the sine is still present at the Sine output (you can still then use the sine output for LFO duties for example). This makes it possible to use the module for processing external sound sources such as field recordings, drum machines and other oscillators.

The Feedback input accepts all kinds of signals, both cv, triggers, gates and audio rate. There are two attenuators for feedback and wave cv. Tracking when calibrated should be around 4-5 octaves.
