BugBrand Binary Block Voltage (BBV) - rough overview


"The BBV is a logic controlled preset/sequencer.

Here I show a little how you might approach controlling it..
The DDSR would also be good - indeed you could also use lfos (sync'd or not) or any other voltage source..
A quick & rough video - hence why you can't see the LEDs of the module very well for most of it..!"

"The Binary Block Voltage (BBV) is a logic controlled 8 stage preset selector/sequencer.

One of the eight voltage stages is selected based on the settings of the 3 logic control inputs, each of which can be set Logic Lo/0 (Mid), Hi/1 (Up), or controlled by an external signal (Down). As each logic input can be separately controlled, a variety of stage sequence variations can be created and moved between. Traditionally you might use various clock divisions to step through stages in a repeating fashion, different from sequential approaches, but comparators on each input (threshold c.+1V) mean any modular signal can be used as a control.

The three digits under each stage correspond to the 3-bit logic input or can be thought of as controlling (see extra image above):
A – toggles each pair of stages, with logic Lo/0 selecting left and logic Hi/1 selecting right
B – selects the top (logic Lo/0) or bottom (logic Hi/1) block of 4 stages
C – selects the left (logic Lo/0) or right (logic Hi/1) block of 4 stages

The output voltage can be switched for low (0 to +2V) or high ranges (0 to +10V)."

  1. Love the concept and most of the execution of this module.

    Trying to wrap my head around how the labeling-assignment of knobs-stages-positions makes sense?
    The upper left is corner of the lower four bit and the lower right is corner of the upper nibble.
    Nibble is a good term since them intermingle and 'nibble' each other in this present layout.

    Makes for a very hard to use module at first glance. And still at second look too. :(

    Can anyone explain how the left right haphazard bouncing from 000 to 111 is used in a sensible way? Is the module meant to be intentionally obscure in its labeling as some form of happy accident creation tool?

    I can see at least four other knob-stage-position assignments that seem much easier to follow and use.

    I respect Tom's skill in module design so I hope there's some logic I'm just not seeing here?
