1. User Interface


Please take care of your hearing and equipment by using this application with caution.

Source inputs

This is the section where you play all your music for Amp FreQQ to process

Track A and Track B are the digital file players. (WAV MP3 FLAC M4A)

3 methods to load and play tracks

  1. Use the button marked LOAD on the image. This will open up a finder or Explorer window, select your file and open
  2. Select your track using Finder or Explorer and simply click, drag and drop to any of these zones marked in blue
  3. Use the built in Playlist feature. Please see HERE

In1 & In2 are auxiliary inputs and will accept audio from any source* ie. Turntable (Vinyl) , CD, Mobile Phone, etc

  1. Any source that is plugged into your connected interface in inputs 1 & 2
  2. Any source that is recognised in our audio setting input options (USB Mic or USB Turntable)
  3. Any source routed in via a third party app (Interapp audio routing) or if available directly in our audio setting input options . ie, YouTube, Spotify , DJ Apps**, DAW etc

There also two momentary trigger sends (REV and ECHO) that send audio from any of the Source Inputs to the FX Processors. This method allows for more accurate engagement of the FX and is the proprietary method of the FreQQs operation. In combination with the built-in bandfilters , the FX delivery works like magic to help you blend in new sound into your music ūüôā

*Please refer to our Turntable routing diagram on this page Audio Interface & routing

**If you use a dedicated controller with built-in audio interface then some of the budget models may not work in this method. Please see Audio Interface & routing



Playbars are where you can see the name of your current loaded track and the time left display. You can also skip along a track here

  • Normal Mode¬† –¬† Playbar displays current loaded track
  • Playbar View mode – Playbar now highlights and displays the current selected file in the playlist

To enter playbar mode by mouse, click the time left display.  Both A & B are mapped to toggle on/off with keyboard spacebar (Press twice first time) . To map on midi please use the time left sections as the midi point to assign to a midi toggle button


Killer switches are uniquely designed kill switches that give the user, visual band-width control of frequency and gain control for each band. To a certain extent, this will allow tuning of both the track being played and the speaker set up in use. These Filterband gain levels come set at 0dB on default settings.This is the maximum, however there is additional gain available of¬† up to 12 dB (safe mode). Please Use with caution and should be used to effectively remaster incoming audio for correction of unbalanced recordings. In other words you can use these gains like 4 band graphic EQ. But can of course be used as “performance EQ”

The Frequency range for each band have been carefully chosen to provide as flat as sound as is possible, while retaining some colour to give a “sound system” sound delivery.¬†We do not recommend adjusting these, however if you do, please try to ensure that the adjacent band/s are adjusted to meets the frequencies you just changed to avoid dips. This is an open system and there are no rules, so feel free to adjust and experiment with caution.

The VU meter displays the amount of signal being sent out to master from each of the killers. Before adjusting any killer faders, please ensure that there is sufficient 

  • To set the bandwidth, click on the right margin of the width control box (It will highlight Red) and drag narrower or wider to your desired bandwidth, then click and drag horizontally into the chosen position. Set the fader to boost/Cut as required using the fader. Note; you can actually push the Sub bass band further to the left¬† (lower) to catch those really low end frequencies

Default & Adjustable frequency centre ranges .

Q / Bandwith cut off points are unrestricted in both user and advanced modes (Narrower will create a peak and restrict frequencies and wider has the opposite affect.

Sub Bass    37-97 Hz РAdjustable 20-150 Hz

Bass   95 Р253 Hz РAdjustable 95-300 Hz

Mids   250 Р3508 РAdjustable 250-4000 Hz

Tops   3509-20000 РAdjustable 20-150 Hz


3 Way Display panel & Custom Logo 

This panel has three displays that can be selected using the 3 way Radio switch 

  1. Displays the Spectrum Analyser that receives its signal from Master out * Note: Switch (Top right) Is to select logarithmic or linear FFT
  2. Displays the 10 band and 4 band equalizers
  3. Displays static image

*Drag and drop any image with transparent background onto the spectrum Analyser to display custom logo (On 1 & 3)

Image size 700 x 200 pixel. By using different level of transparent background you can make some nice effects

The app will remember the last loaded image


This are an additional auxiliary inputs for a Mic and or Dubsiren, instruments etc

These are set on Amp FreQQs Inputs In3  & In4

  • To set your Mic or Aux, Open Settings, audio settings, then IO settings. Select your audio interfaces channels that you wish to assign on Input 3 & or 4.

If your audio interface supports separate inputs as channels then in theory you can assign up to four independent inputs. Two on Source Inputs and two on Mic/Aux. Each with their own independent FX trigger sends.

For other advanced routing please see additional information at the bottom HERE…


EQ Selector

We have a unique 3 way EQ system. The Killer bands operate in a way to allow adjustment of frequency bands, hence a type of Parametric EQ. These will be sufficient for most needs, but we also have additional 10 band parametric and 10 Band Graphic EQs, which can be use in any combination with the killer bands.

10 band Graphic and 4 Band Parametric


10-Band Graphic EQ gives subtle amounts of tone shaping and level control. With ten carefully chosen frequencies, It will let you boost or cut by 12dB

4 Band Parametric Equalizer offers a way to EQ before the audio arrives at the killer bands

  • Freq – Frequency
    This determines where the range set below is positioned in the audio spectrum.
  • Range
    This determines how wide or narrow the EQ band is. A setting further clockwise will narrow the range. There Is a dynamic display which shows the current set range. In the Image for example the Bass Is set to 85hz to 248hz.  Use in combination with Freq to set a group of frequencies to affect
  • Gain
    The EQ have little or no affect without some gain or reduction. USE WITH CAUTION, VERY POWERFUL




  • This is a switchable high pass and low pass resonant filter. Simply turn clockwise to engage the filter and anti-clockwise fully to put it back to idle.
  • The switch determines which filter will be engaged and you can switch anytime
  • The Q slider controls the amount of resonance from 0 to 10
  • The routing selector –

A Works on source signal only

B Works on master signal

C Works on Samples only



Dub Siren Setup screen


This is a custom designed Dub Siren with live variable controls

Click Setup to open the main Siren Panel


  • Base Freq – Base frequency controls the pitch
  • Rate – Sampling rate *
  • Bits – Bitcrusher *
  • Depth – How pronounced that wave’s curve is (Square and Sine)
  • Rate – Rate is the frequency (meaning “how many times”) the wave generated goes from top to bottom (Square and Sine)
  • Chop – it as a commutator that acts as a very simple arpeggiator
  • Echo send level ‚Äď amount of echo send level sent when echo trigger is engaged


  • Open – load any saved sets of presets you have made
  • Save – Simply change any settings on the siren ,select next preset, adjust again, once you have setup all 12. click save and name
  • Default – This will load FreQQs own siren presets
  • Echo Level – This controls the amount of signal routed to the Echo FX (When echo send switch is on)

Sample player


Twelve slot sample player can be used to play any audio clips such as jingles, adverts, dub siren clips or any other samples. They can be played via a dial and momentary trigger or via single buttons controlled via midi. There are also independent reverb and echo sends, that can be momentary triggered via the keyboard or midi control. The HP fltr is high pass filter to remove unwanted bass frequencies

In addition to this, whole tracks can be played through the sampler and you can use the bypass switch (BP) to have a cleaner (bypasses kills) signal to record

Samples can be loaded in several ways.

  1. Click and drag a single sample and drop into the samples section (Or click load)  in the main app interface, then turn the dial and repeat the process. 
  2. You can also select several samples in Finder or Explorer  (up to 12) and drop them directly into the area marked in Blue.
  3. Open the panel, click and drag single samples to individual sample slots one by one. Hovering over sample slots displays the loaded sample or audio file. Echo send level is also provided.

When a sample is loaded, the slot will turn part yellow. When sample is engaged the whole slot displays yellow.

The switches to beside each slot, allow you to select momentary or full playback of the sample.

Samples are saved on exit and no need to reload


Default settings should work as a good starting point.

Both processors bypass the kills and go straight to Master. They also include band pass filters in their audio paths, therefore opening up creative expression that fits better into the music being played. Press the trigger send on any of the sources at the right times and musically interact with your track to create a special version.

NOTE : Amp FreQQ FX Delivery does not work in a way you may be used to. The send and return controls should be set up and left. Use the send triggers from the audio sources to deliver to the FX Processors. The gain controls the Band filter gain and is the best way to balance the sound the blend into you source audio.

Both of the FX processors have a graphical display, with frequency centre, bandwidth and gain control.

  • To set the Q, click on the right margin of the control box (It will highlight Red) and drag narrower or wider to your desired sound. Wider will allow for a fuller sound,
  • Click and drag anywhere on the graph horizontally to select the frequency¬†group you want to effect and v
  • Click vertically to cut or boost.
  • If you hover over the any band with your mouse you will see the settings currently chosen in white, with the centre frequency, gain and Q.(also when any movement of controls is detected)

Please note the spectrum analyzer only displays the affected sound on the effects processors


This is located in the panel area. Each FX limiter is set on as default, please adjust these depending on your needs. Sliding the fader to the left will reduce the overall output gain available. These can be used both for protection and creatively.
