Buchla 272e Polyphonic FM Tuner
“An early experiment. all sounds initially generated by the 272e Polyphonic FM Tuner heavily processed by the 285e Frequency Shifter and 291e Triple Morphing Filter.”
This module is the e series reincarnation of the 285. A long time coming, but well worth the wait.
The top section performs frequency shifting; up and down outputs are simultaneously available. The reference frequency can be externally applied or internally generated; the latter can be voltage controlled and f.m. modulated. The bottom section is independent, and functions as a balanced modulator of applied signals. The degree of modulation is voltage controlled, and the reference frequency can be internally generated or externally applied, as in the frequency shifter. A separate output is dedicated to classic ring modulation, a subset of balanced modulation. All settings of the 285e can be stored and retrieved with the 225e or the 206e preset manager.
