A-149-3 is a new third module of the A-149-x range, based on the "Fluctuating Random Voltages" by Buchla.
Buchla avoided calling it a “noise” or “random” module — he preferred the mystical, poetic “Source of Uncertainty"

Basically it is a random voltage generator that features Quantized Random Voltages (stepped, like a broken sequencer) and Fluctuating Random Voltages (smooth, like a stoned LFO), offering both jagged and fluid unpredictability.
Used by pioneers like Morton Subotnick, the Source of Uncertainty helped shape electronic pieces that felt alive and organic
Compared to the historic original a lot of functions have been added in this module.
The user has access to virtually all internal signals (e.g. Noisy Triangle or S&H) and there are a lot of adjustable parameters which were fixed in the original like the frequency and noisiness of the internal triangle oscillator, the correlation of the S&H and manual or automatic frequency control of the S&H clock oscillator.
The fixed internal connections of the original are wired to sockets in the A-149-3 and can be used also individually as the connections of the original are realized as normalled sockets.
That way e.g. the S&H or slew unit can be used independent from the other units.
The Source of Uncertainty continues to ripple through modular design today.
Already other options were available to get this typical west-coast-style module into Eurorack.
TipTop clones like 266t, 266e, or modules inspired by its concept like Mutable Instruments Marbles
While I do have other modules on my want-list that I have to get first, this will probably end up in my rack at some point... next to it's precursors A-149-1 and 2.
Those were a lot of fun to experiment with and I expect this will be a lot of fun too.
