With Buchla’s official blessing, engineers and sound designers at Tiptop Audio have meticulously and faithfully re-created the vintage voltage of the West Coast synthesis pioneer’s 257 Dual Control Voltage Processor, with the 257t. Buchla’s iconic – and often esoteric – design ethos is now available in a fully-compatible, 14HP Eurorack module, uncompromising in delivering the full scope of voltage manipulation offered by the original 25. Like its historic counterpart, the 257t utilizes two identical, independent sections of CV modulation, boasting a straightforward interface undergirded by complex mathematical equations to produce wildly compelling sonics. Voltages are blended into a singular output, with addition, subtraction, scaling, inversion, and multiplication processes, as well as voltage-controlled transfer between two CV inputs.
