Effect Rack

The Effect Rack gives you full control over every effect in Cubasis.

Many linear effects feature a Mix fader. This parameter controls the percentage of processed sound that is mixed to the original signal.

Note: Non-linear effects are dependent on dynamic parameters, as opposed to linear effects. The compressor is a prime example of non-linear signal processing, as the amount of gain reduction depends on the current volume level.

The round Preview button to the left allows for quickly testing the effect with a MIDI instrument.

Inter-App Audio

Inter-App Audio is a universal routing system for iOS, allowing you to route audio, MIDI and effects between Cubasis (host) and compatible node apps in realtime.

Find more information here.

Audio Units

Third party apps with Audio Unit functionality can act as instrument or effect plugins / addons that integrate directly into the Cubasis workflow.

Effect presets

Press the Presets button to the top left of the rack and a list of presets will open below. Tap a preset to load it and apply it to your effect. Cubasis features factory presets for both internal effects and FX packs.

Note: Presets are not visible in the MediaBay; deleted presets can be restored from the Trash folder via the WiFi Server or iTunes File Sharing.

Channel Strip

The channel strip module is an effect suite hard-wired into every channel and contains the following effects:

RoomWorks SE

RoomWorks SE

Note: The RoomWorks SE plugin is available to all users registered at MySteinberg.

RoomWorks is a high quality digital reverb simulation plugin. It has the following parameters:



Reverb simulates a certain type of space (e.g. room, hall) surrounding your sound and reflecting it.

  • Predelay: Period of time before the effect sets in. In larger halls, it often takes a fraction of a second before the reflected sound is audible. Note: This parameter cannot be automated.
  • Time: Amount of seconds in which the reverb is audible. The more time, the larger the emulated space seems.
  • Brightness: The brighter your reverb, the more higher frequencies are emphasized and vice versa. This is useful for setting the right atmosphere.



Delay repeats your sound, creating an echo effect.

  • Time: Normal leaves the beat unchanged, whereas Dotted extends it by 50%; Triplet changes the 1/4 meter to 1/3.
  • Beat: Sets the interval of the delay, which also depends on the song tempo.
  • Feedback: Higher feedback increases the number of delays and therefore the duration of the effect.



The 4-band equalizer (EQ) controls the strength of all audible frequencies within your sound, allowing you to cut or boost various frequencies. For this purpose, 4 bands are provided, displayed as number handles (1-4) on the graph and their properties specified in the columns labeled eq 1-4 below.

  • On / Off: Provides the option to turn off unneeded bands.
  • Gain / Slope: (y-axis) Volume alteration of your band's frequency. Values above 0 dB result in a boost, negative values in a cut.
  • Frequency: (x-axis) Determines the band's center frequency.
  • Type: EQ bands 1 and 4 can act as parametric, shelving, or high/low-cut filters, while EQ bands 2 and 3 are always parametric filters.
  • Q: The Q-Factor controls the bandwidth. Reduce it for filtering accross broader frequency spectrums, or turn it up for more precise control. Note: This parameter cannot be automated.
  • Double tap a number handle to reset its corresponding band.
  • Pinch on a number handle to adjust its Q-Factor.

On top of the assignable insert effect slots a permanent StudioEQ instance is available per track for quick access, as well as the Channel Strip effect suite. If desired, additional StudioEQ plug-in instances can be inserted manually.

Shelf EQ

The Shelf-Equalizer simply lets you control the strength of low (Bass) and high (Treble) frequencies within your sound.



The Compressor is useful for mastering tracks as well as your whole song. While it lowers peaks in your wave material that might otherwise cause clipping, it allows you to raise the general gain of your song, therefore adding more power to the final product.

  • Threshold: If your sound is louder than the threshold level, it gets reduced.
  • Ratio: Determines the amount of sound reduction, e.g. if your ratio is 1:6 and your sound reaches 6dB above the threshold limit, it will be reduced by 1dB.
  • Attack / Release: Specifies the amount of time it takes to reach full compression / to get back to 0% compression afterwards.
  • Output: Determines the volume level of your processed sound.


The Limiter lets you fine-tune your sound's gain (volume).

  • Drive: Multiplies your audio signal before entering the limiter.
  • Attack / Release: Specifies the amount of time it takes to reach the highest limitation level and how long the effect lasts afterwards.
  • Output: See compressor.

Brickwall Limiter

The Brickwall Limiter ensures that audio signals (even short ones) always stay below a set limit without creating audible artifacts.

  • Threshold: Sets the lowest input level in dB where reduction kicks in. If the input signal exceeds the threshold, the gain is reduced.
  • Release: Specifies the duration the reduction lasts after the input signal falls below the threshold.
Note: The Brickwall Limiter is set at the end of the audio signal chain, i.e. as the last master insert. To access it, open the mixer and choose the symbol on the Stereo Out channel. If the Gain Reduction meter indicates constant limiting, try raising the threshold or lowering the overall gain level of the input signal, as the Brickwall Limiter is primarily designed for cutting occasional signal peaks.

Noise Gate

The Noise Gate filters out audio signals below certain volume levels, reducing unwanted noise artifacts in the process.

  • Threshold: If your sound is quieter than the threshold level, it gets reduced.
  • Range: Determines the amount of sound reduction by the gate. For example, set the range to 50% to half the gain of all signals below the gate threshold.
  • Attack / Release: Specifies the amount of time it takes to reach full gating / to get back to 0% gating afterwards.
  • Output: See compressor.

Spin FX

The Spin FX unit offers a wide variety of DJ-like style breaks, tape stops, stutters and filter effects that can be triggered live and recorded via the Automation Write mode.

  • Time Grid: Sets the measurement that all effects will be relative to. Selecting the sixteenth note for instance will make every effect play four times as fast / short as the quarter note.
  • Filter: Works like the Filter insert effect. See below for more information.
  • DJ (Red): Includes a Backspin, two Scratch and four Tape Stop / Start effects.
  • Stutter / Slur (Green): Generates a slice of the current audio stream as long as the selected measurement relative to the time grid and repeats it as long as the button is pressed. Pressing 2 or 4 will stretch the audio by said factors.
  • Cycle (Blue): Repeats the next 1 / 2 / 4 beats.
  • Staccatto / Mute (Yellow): Either toggles the audio on / off every beat or mutes it entirely.



Using the Filter, you can cut off either high or low frequencies of your sound and control its resonance.

  • The cursor controls cutoff and resonance at the same time. The higher vertically, the higher the resonance. When moved to the right, the cutoff gets higher.
  • HP (Highpass): Only lower frequencies are dampened. The sound remains unchanged if the cursor is positioned at the far left.
  • BP (Bandpass): Enables low and high cutting, the sound remaining unchanged if the cursor is in the middle of the pad.
  • LP (Lowpass): The opposite of Highpass; high frequencies are dampened. Move the cursor to the far right for the original sound. Note: The filter type cannot be automated.


The Chorus effect enriches your sound by having multiple sources playing it (e.g. ensemble) with frequency modulation.

  • Depth: The amplitude of the modulation. More depth means a higher pitch discrepancy within your sound.
  • Rate: A higher rate increases the modulation speed.


Flanging your sound takes the chorus effect to the next level, creating a metallic sweeping effect.

  • Depth: See Chorus.
  • Rate: See Chorus.
  • Feedback: Feedback controls the intensity of the resulting sweep effect.


Similar to the Flanger, the Phaser creates a sweeping effect, sounding even more synthetic and extraterrestrial.

Amp Sim

The Amp Simulator digitally emulates a physical amplifier (such as guitar or bass amps). 8 different models are available. Note: The model parameter cannot be automated.

  • Drive: Increases the sound level, creating an overdrive effect.
  • Treble: Determines the amount of high frequencies.


The Overdrive effect adds distortion to your sound by clipping it.

  • Drive: Determines the distortion intensity.
  • Gain: Controls the resulting volume level.

Phase Inverter

This utility inverts the phase of your track, i.e. it flips the audio signal vertically. It can be useful for detecting phase shifts or other unwanted side effects as a result of stereo recording.
