OSD (OR / SUM / DIF)

OSD, aka OR SUM DIF, is 3 independent blocks of useful utility in 4HP.  OSD is centered around combining voltage in useful ways. Audio, V/Oct, and control voltage are at home in this utility. OSD offers a fully DC coupled signal path with precision components to make this happen.  High quality, configurability, and compact size ensure OSD will always find it's way into your patch. - Combine v/Oct sequences with precision summing, or enable the the precision OR circuit for completely different results.  - Mix two envelopes or an envelope and lfo using sum to create large accented voltages or combine with OR to keep the output  in the original range. - Crossfade between audio or control voltage using the potentiometer in block one. Setting DIF will invert the signal at the B jack. What is OR, SUM, and DIF? OR - Input voltages are compared and the higher of the two is passed to the output.  For example if A = 4V and B = 8V, the output will be 8V. SUM - Input voltages are added together t
