Buchla Easel and a 4U expander


Published on Dec 5, 2015 Nicolas Lévy

"Added a few modules to the Easel.
247v by Verbos
259r built by Roman
And a Modcan 59a delay DIYed in Buchla format.

In this patch the most noticeable effect is achieved by having the pressure controlling the delay feedback.
The 259r is modulated by the 2nd cv out of the 247v, the easel mod osc and the easel envelope.
The 247v is sending pulses at each step to clock the 59a. When it skips a step it gives the nice "rolling" effect in the sequence.
The sequence is the Easel complex osc, no envelope, just the 247v steps out sending pulses to open the Easel VCA/LPG."
