01Overview

Buchla Easel V recreates Don Buchla's Music Easel, a rare 1973 instrument that helped shape experimental West Coast synthesis. Arturia says the model was built down to the component level and extended with features the original lacked, including up to four voices of polyphony, a noise source and a feedback loop in the preamp. The plugin is aimed at producers who want to build unconventional, evolving sounds through patching rather than a traditional keyboard-first workflow.

Sound Design and Patching on the Easel V

The instrument centers on complex oscillator design, AM and FM synthesis, and gate and filter combinations that the developer describes as uniquely percussive. Patching is color-coded, and only valid targets light up when you drag a patchcord, which reduces wasted connections.

The original design lacked a noise source, so Arturia added one to the preamp, which can help introduce rhythmic elements. A feedback loop in the preamp allows for howling, feedback-driven tones. Modulation sources include a 5-step sequencer, an envelope generator and a pulser, and the Pulser and Clock can be synchronized.

Modulation, Sequencing and Effects

The Left Hand section offers five Function Generators that can be routed to any of 76 modulation targets. The Right Hand section provides a step sequencer. Gravity is an X/Y modulation source that uses a bouncing-ball physics model influenced by attraction, repulsion and collision to generate unexpected modulation signals.

A two-slot Effects section adds processing directly inside the plugin. The effects list includes phaser, flanger, chorus, overdrive and delay, and a Vactrol modeling control offers fast, medium or slow response.

What do I need to run Buchla Easel V?

Buchla Easel V runs as a Standalone application or as a plugin in a compatible DAW. On macOS it requires OS 10.13 or later, 4 GB RAM, a 4-core CPU at 3.4 GHz or an Apple Silicon CPU, 3 GB of free disk space and an OpenGL 2.0 compatible GPU. On Windows it requires Windows 10 or later (64-bit), 4 GB RAM, a 4-core 3.4 GHz CPU, 3 GB of free disk space and an OpenGL 2.0 compatible GPU. ARM processors are not supported on Windows.

How much CPU does polyphony use?

Arturia notes that each voice of polyphony requires significant processing power, approximately 20 percent of an i7 CPU per voice.

Does Buchla Easel V include presets?

Yes, it includes 256 factory presets. The redesigned preset browser lets you search by name or tags and mark favorites, comments and playlists.
