Doepfer A-149-3 Eurorack Fluctuating Random Voltages Module

A-149-3 is the third module of the A-149-x range.

In this group, Doepfer presents several functions of Don Buchla’s “Source of Uncertainty 265/266” (SOU) modules that cannot be realised with existing A-100 modules. Some functions of Buchla’s 265 and 266 SOU can be realised with existing A-100 modules. For details please refer to A-100 patch examples.

Module A-149-3 is based on the homonymous “Fluctuating Random Voltages” by Buchla. Compared to the historic original a lot of functions have been added. For example 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. For example 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.
