144 Dual Squarewave Card Expander for Buchla Music Easel

4U Shop 144

The 144 Dual Squarewave Card from 4U Shop is an expander card for the Buchla Music Easel, providing a one-to-one replica of the original 144 module from the 100 series. Like the original, it produces two raw square waves, the frequency of which can be controlled independently and externally with CV, or through manual control with the Frequency Control knobs. Each square wave is equipped with two outputs, giving you four in total for even more cross-modulation potential. Like the original, each channel offers AM and FM CV inputs, along with dedicated attenuator knobs for each input. The 144 Dual Squarewave Card from 4U Shop expands your Easel with a classic and flexible Buchla design, taking every modern modular experiment two steps further.
