CV/gate adapters for Buchla instruments
A plug and play adapter card is available for the 208 and Music Easel These adapters ease interfacing of Buchla
gear with non-Buchla equipment.
Each small board (max 25x32mm) can be soldered directly to a Cliff minijack socket and installed to a boat or panel or mounted with a screw (3.2mm mounting hole). The boards come unpopulated without parts. Please contact me to order pre-built ones. Buchla pulse generator
Turns non-Buchla gate signals (+5V to +15V) into the typical Bucha pulse (+10V pulse followed by a +5V gate) required for proper sustained/transient envelope behaviour. It is based on the Buchla pulse generator circuit used by Dave Brown for the 218r rev2 pulse modification.
