Note: The UAD Roland CE-1 plug-in is no longer available for purchase. It has been replaced by the UAD Brigade Chorus plug-in, which uses the exact same algorithm.

Unmistakably captivating stomp box stereo chorus and vibrato

Even for the mix engineer, stomp boxes can provide "secret weapon effects" not found any other way. In 1976, BOSS (a subsidiary of Roland) originated the chorus effect pedal, and nobody has come close to matching the CE-1's captivating chorus sound since. Its unmistakable warm analog stereo chorus and vibrato have been heard on countless tracks--particularly on guitars, bass and electric keys. Universal Audio has been commissioned by Roland to accurately model the CE-1, and the results are nothing short of spectacular.

• Unmistakably warm stereo chorus and vibrato effects
• Roland/BOSS licensed and stunningly accurate model of original CE-1 chorus effect
• True pitch shifting vibrato

The CE-1 provides a choice of either chorus or true pitch shifting vibrato. The vibrato/chorus "stomp switch" allows for chorus or vibrato effects, while the normal/effect stomp switch bypasses the effect. One knob is dedicated to the chorus intensity, while two knobs allow manipulation of the vibrato depth and rate. When used with stereo tracks, the CE-1 may be used in "classic mode" (L=direct, R=delay) which behaves exactly as the original pedal or "dual mode" which acts as two CE-1's patched using their mono outputs (direct+delay). In this mode, the LFOs are 90 degrees out of phase (quadrature) for maximum L-R spread.

Roland CE-1

Roland CE-1 Controls

The Roland CE-1 has two operating modes, chorus and vibrato. Only one mode can be active at a time. The operating mode is set using the Vibrato/Chorus switch.

Clip LED

The red Clip LED (above the Normal/Effect switch) illuminates when signal peaks in the plug-in occur.

Normal/Effect Switch

This is an effect bypass switch. Click to enable/disable the chorus or vibrato effect. The effect that will be heard is determined by the Vibrato/Chorus switch.

The active state is black text. The inactive state has gray text. The default state is effect.

This is not a plug-in bypass switch. The hardware CE-1 has a slight effect on the sound even when the effect is "bypassed" in normal mode. We have modeled the plug-in faithfully and like the hardware unit, when the effect is bypassed with this switch, audio is still processed to sound like the CE-1 in "normal" mode. To disable audio processing, use the CE-1 Power Switch.

Rate LED

The yellow Rate LED (above the Vibrato/Chorus switch) blinks according to the current low-frequency oscillator (LFO) rate. When CE-1 is in Vibrato mode, the LFO rate is determined by the vibrato rate knob. When in Chorus mode, this LED is effected by the Intensity knob.

Note: In Chorus mode, the fastest LFO rate is slower than the slowest LFO rate in Vibrato mode.

Vibrato/Chorus Switch

This switch determines the operating mode of the plug-in. Click to switch between chorus and vibrato modes.

The active mode is black text. The inactive mode has gray text. The default mode is chorus.

Stereo Mode Switch

The Stereo Mode switch determines the operating mode of CE-1 when the plug-in is used in a stereo or mono-to-stereo configuration, such as a stereo audio track insert or stereo effects bus.

The hardware CE-1 has only a monophonic input. Its output can be mono (wet and dry signal mixed at one output jack) or stereo (dry signal in one output jack, wet signal in other output jack). We've adapted the model for the modern era, enabling a true stereo input.

Note: This switch has no effect in a mono-in/mono-out configuration.

The Stereo Mode switch effects the output as follows:

Dual Mode

In Dual mode the CE-1 behaves as a dual-mono device, functioning as two independent CE-1's, each running in mono mode on one side of the stereo signal.

The left output contains a mix of the dry left input signal and the processed left channel signal, while the right output contains a mix of the dry right input signal and the processed right channel signal. Additionally, the LFO's of the dual CE-1 channels are 90 degrees out of phase (quadrature) for maximum effect.

Classic Mode

In Classic mode, the CE-1 behavior is similar to that of a mono-in/stereo-out configuration. The left and right channel inputs are mixed to mono, and the dry signal (mixed left and right channels) appear at the left output, and the wet effect signal appears at the right output.

Output Level Knob

This knob determines the signal level at the output of the plug-in. The range is 0 - 100%.

Note: This is not a wet/dry mix control.

Chorus Intensity Knob

When CE-1 is in chorus mode, the amount of chorusing effect is determined by this knob.

Note: When in vibrato mode, chorus intensity has no effect.

Vibrato Controls

These two knobs control rate and depth of the vibrato effect when CE-1 is in vibrato mode.

Note: When in chorus mode, the vibrato controls have no effect.

Depth Knob

The depth knob controls the intensity of the vibrato effect.

Rate Knob

The rate knob controls the rate of the vibrato LFO. The rate is indicated by the the Rate LED indicator.

Power Switch

This switch determines whether the plug-in is active. This is useful for comparing the processed settings to the original signal, or to bypass the plug-in to reduce the UAD DSP load (load is not reduced if DSP LoadLock is enabled).

Click the rocker switch to change the Power state.
