The 266t includes two sections of generation and modification, with two different processors and four generator types with one producing three typed of analog noise - flat, -3 dB/oct, and +3 dB/oct. You can tune your range to a fixed amount of possibilities, depending on the output, with n+1 output being more localized to the 5V range and the 2^n output having equal opportunity across all 10 volts.
West Coast Synthesis for Eurorack Exploration The good folks at Tiptop Audio have forged an alliance with Buchla, the West Coast pioneers of synthesizer esoterica, to bring some of their formidable voltage to your Eurorack setup. A slew of design differences have long prevented the melding of these two worlds, but Sweetwater’s synthesists are impressed with Tiptop Audio’s engineers careful studying of Buchla’s classic 266 Source of Uncertainty module to Eurorack specs while preserving its historic potential. Modulation capabilities include a host of randomization techniques, noise generation, and sample and hold options.
