Soundfreak Buchla Format EMS Modules



See the Superbooth 22 video here, and announcement post here. These are licensed from EMS. The prices have gone up slightly since.

"The Triple Oscillator consists of three independent oscillators. They are identical in controls but different in range and waveforms.

From top to bottom, the three oscillators are labelled 1, 2, and 3, and horizontal lines visually separate them on the panel layout.

The original VCS3 oscillators had a frequency range that extended well below the audible range. This allowed the musician to use them both as sound or modulation sources, mainly thanks to the VCS3 matrix, which allowed a flexible and immediate signal routing.

In the 4U format, where sound and modulation are strictly separate, we provided the oscillator with both Tini-Jax and banana sockets.

The Dual Filter/Oscillator consists of two independent, identical filtering circuits modelled over the Filter/Oscillator section of the VCS 3, with some extra features.

We preserved the original, distinctive Response parameter that allowed you to use the device as a resonant low-pass filter or a self-oscillating bandpass filter. In the latter configuration, the filter produced a pure sine wave that could be used as an audio source.

In addition to that, we designed an FM circuit that allows you to control the filter’s cutoff frequency with both CV and audio signals. A dedicated switch modifies the filter reaction to audio-rate frequency modulation.

The DB switch allows you to change the filter slope from 24 to 18 dB/oct, thus expanding the capabilities beyond the original VCS3 design.

This module merges two separate sections of the VCS3: the Envelope Shaper (upper part of the front panel) and Noise Generator (lower part of the front panel).

The Envelope Shaper combines a VCA and a loopable envelope generator that can work as an LFO. The envelope both controls the VCA level and is available as control voltage.

It can accept up to four distinct sounds thanks to four semi-normalled audio inputs.

The Noise Generator outputs a noise signal with controls over its amplitude and colour. The colour knob defines its timbre by cutting the low or the high frequencies from the default white noise. We chose to expand its design by making this last parameter voltage-controllable.
