I am beginning research in utilizing simple bioelectrical readings to be used in place of an LFO circuit for a traditional analog synthesizer. My desire is to use EEG readings to influence the sound produced by a musical instrument. Unfortunately the very delicate and precise nature of EEG readings make the related hardware relatively expensive and difficult to construct. (although the OpenEEG project’s research is diminishing that fact) ECG hardware is much more approachable in terms of budget and experimentation. I will begin by constructing simple ECG and VCO circuits and then adapting the ECG output to conform to standard LFO control voltage parameters. My hope is to create an instument whose voice is dynamically augmented by the physiological state of its user.
more to come . . .
