His turn-ons are inversion, attenuation, and his turn-off is muting
Your Eurorack modular synthesizer is loaded with modulation possibilities. Dozens of control inputs; each needing a signal to wiggle it. Each control expecting a different range of voltage. You’ll find that things get so crowded, you need a remote control for those hard to reach knobs! And sometimes you just want everything to stop with the flip of a switch. Very soon you learn that duplicating, reducing, inverting, offsetting, and muting signals is the key to repeatable and nuanced modulations.
BUFFJRVS was built precisely for these reasons.
And he’s here to help.
He’s a 3 channel, 9 output, voltage pal for your Eurorack synthesizer. His turn-ons are inversion, attenuation, and his turn-off is muting. Weighing in at a svelte 10HP, with a skiff friendly backside (don’t tell him), this little guy can find his way into the tightest racks.
Each channel can attenuate, invert, and mute CV and audio signals. As a multiple, it’s buffered outputs let you route 1-3 signals to 9 destinations. Without input signals, you can produce 3 separate CV offsets from -10V to +10v. Use this macro-control to manipulate multiple modules or module parameters simultaneously. All input signals cascade from output jack A1, through the B channel outputs, terminating in output C3. If nothing is present at input, a 10v offset is present at the outputs. If a channel’s switch is down, it is removed from the cascade (“Independence”). If the a channel’s switch is up, it joins the cascade (“Voltage Calculator“) and the channel A knob governs the primary gain.
The Voltage Calculator is operated as follows:
IF A=5v, then B=5v, when Channel B’s potentiometer is at full clockwise (0 attenuation).
IF B=5v, then C=5v, when Channel C’s potentiometer is at full clockwise (0 attenuation).
Changes made to a channel’s potentiometer will affect the next channel in the chain.
IF A=5v, then B=2.5v, when Channel B’s potentiometer is at 12 o’clock (50% attenuation).
IF B=2.5v, then c=1.25v, when Channel C’s potentiometer is at 12 o’clock (50% attenuation).
CHANNEL A’S POTENTIOMETER FADES ALL CHANNELS.
