Effects 1-3 (under Devices menu) are all identical and each has a selector to select which effect chain to show below.
Effect view, first popup selects which chain group to edit/view, the second popup selects which chain to edit/view.
Chain is a series of effects, such as Filter > Reverb > Filter > Delay (total of 4 effects). Effects are shown in order they are processed: topmost device on left is processed first (audio input), topmost device on right side is next (audio input of it is the audio output of the first device), then the second row from the left and so forth...
Effect chain with filter, reverb, delay and another filter.
Decks AB effects are for the A+B main decks. When editing the chain of these effects, the chain is duplicated so that both decks (on left and right) have the same effects in the same order.
Main is all audio output of Disco XT, this processes the final audio output of decks, microphone, sampler, only master limiter is applied after these effects.
Decks C, D and E all have separate effects.
Each of these effect chain groups from the first popup can hold up to 10 effect chains, this is selected in the next popup "Chain 1...".
In case of sampler, unlike the other chains, the chain number (Chain 1, Chain 2) indicates which sampler this chain is for. So Sampler > Chain 1 is for Sampler 1, sampler > Chain 2 is for sampler 2... Although the device menu of the main menubar by default shows only Samplers 1-3, in preferences the number of samplers can be increased to a maximum of 10 samplers.
'Edit Chain' button, click the button to show a menu:
This is a quick disable/enable switch for all effects in the chain, each individual effect also has a bypass (ON/OFF) switch shown graphically.
Select 'Edit Chain' to add/remove effects from the chain in the 'Edit Chain' window. To add effects, double click or drag items from the list on the left to the list on the right. To remove an effect double click the effect.
Effects can also be removed by right-clicking background of an effect device and select 'Remove'.
Removes all effects from this chain, this can be done in the edit chain window too and is just a quicker option.
A quicker way to add a new effect type as last item to this chain.
Preset saving/opening is available for both individual effects and for chains (containting all effects in the chain).
Single effect presets can be saved that contain the modified effect parameter values for later access (folder button on the left side of an effect). Created effect presets can be removed or renamed in Edit menu > Effect Presets...
Effects preset menu.
Effect chain presets are loaded by either:
Replace: Removes any effects currently in the chain and loads the effect types (and parameters) from the preset.
Add to Top: Does not remove any effects that are already in the chain. Adds the effects in the preset to top of the chain, so any effects already in the chain are moved downwards.
Add to End: Does not remove any effects that are already in the chain. Adds the effects in the preset to th end of the chain.
Next is name field, double click to enter a name for this effect chain / chain preset. Giving a name for the effect chain is required before it can be saved as an effect chain preset.
After you have added one or more effects that are then shown below this effect chain editor:
Background of an effects can be clicked to show a menu:
Copies current parameters of this effect type so you can then right-click another effect of the same type and paste the parameters there.
Reset parameters to default values.
Same as clicking "OFF | ON" switch in the top-right corner of effect. When set to OFF, audio is not processed but bypassed, so next effect (if any) receives the input of this effect instead of output.
Moves the effect up in the chain. Depending on effect settings, the order in which the effects are processed might matter.
Removes this effect from the chain.
Adds effect of the selected type to the chain and moves the effect you clicked on down/right in the list.
Often produces robot like sound, similar to the delay effect with a very small delay, has LFO (low frequency oscillator) to vary the delay, feedback and other parameters.
Includes simple volume, gain and panning controls. Notice that the dry/wet affects controls such as volume.
Creates a delay-line/repeat/echo of the input signal after a set time delay. When time delay is altered while playing, the delay effect's rate control can jump to a high/low rate to match the new time delay.
If this effect type is added to chains 'Decks A, B, C, D, E' or to transition editor, the BPM and output tempo of that deck is automatically available (although not visible, display shows --) and it is not required to tap a BPM value to the effect.
If you do tap a new BPM value it is used instead of the deck BPM and tempo, if you then after waiting for a few seconds click 'tap' button the tapped BPM is cleared (--). The BPM of the effect can be altered with musical rhythm buttons such as 1/16 (shortest delay) and 1/2 (longest delay). For the 'Mod' parameter to have any meaning, the time knob needs to be set to any value less than maximum (this is the modification amount).
For distorting/destroying sound. Features multiple operation stages.
First knob sets amount of gain, second sets additive gain, third one adjusts additive gain.
Disabled at zero.
Usually either high pass or low pass filtering but not both. Q adjust is for both filters.
First param sets threshold value. Second param disables at zero and is fully audible at middle.
Adds a constant gain cut at the set rate/frequency. Disabled at zero.
First knob sets threshold, disabled at zero. Second knob sets saw frequency/pitch.
Clips the signal at 110 %
Adds a time delay from the original audio to some of the stages, such as foldback. This is not a realtime parameter and causes slight silence when changed.
This effect type may be used for such as:
- Creating distortion.
- Reducing louder notes/drums.
- When tempo is adjusted in the decks (EWB4,...) and set to such as 50% tempo, this effect may be added and adjusted according to the material to modify to have a less computerized sound.
Adjustments for this effect are manual adjustments, which means that after adjustments are set (movedthe knobs) will likely produce a different output when type of material changes (different song).
To enable distortion,
Set Filt A and/or Filt B knobs to other than fully left, when the knobs are set fully left, the filters/distortion A/B are disabled.
For other use:
Thresh knobs starting from lowfrequencies to higher frequencies(1-8) adjust thresholdlevel, fully left is near silent, Commonly would be set to around 9'clock.
R(educe) Or Amp knob defines over-the-threshold, to either reduce/damp the loud notes, or to amplify.
Gain knobs 1 2, 3 4, 5-8 adjusts overall gain of the frequency.
Various smooth knobs adjust how rapid/gradual the amplitude changes are.
Ahead and wait should commonly be set to a low value (near left).
Ahead moves the onsets of the loudness to a bit earlier (Lookahead).
Wait holds a note damp/amp. If 'Wait' is set to 0 the output may be distorted (too frequent on/off).
A select from top-right corner to enable completeness for threshold amp/damp.
And on left, to select to use 8 bands (full) or only 6 or 4 bands.
Audio levels dynamics processor, in compressor mode this unit reduces audio loudness differences in the audio (attenuating loud sections while maintaining quieter sections), in expander mode loudness differences are increased (amplifying loud sections above the threshold while maintaing sections below the threshold).
After setting proper threshold by looking at the compression meter at the right side or by listening,
adjust attack (usually small value) and release (usually small value).
Ratio sets amount of compression/expansion. At zero it is disabled.
Post gain sets gain applied after the compression/expansion, this is related to the set threshold level.
Optionally, the compression threshold may be detected through a high pass (HP, ignores low frequencies) or low pass (LP, ignores higher frequencies) filter. These filters are not audible but are only applied to the dynamics.
Clip button enables clipping: Signal is clipped at 110%, may cause distortion, depending on current post gain setting.
Might be useful for visual purposes, does not do anything.
Includes three adjustable EQ filters. Although only one filter can be shown/edited at a time, all three types can be used at at the same time.
Same as "EQ" but this version has a bigger view of the frequency amplitudes. Top knobs alter gain, middle row knobs alter frequency point and bottom row of knobs alter width of the filters. The 'EQ Big Pa' version instead has three parametric EQs, where the 'EQ Big' has low-shelf EQ and high-shelf EQ and the middle is an parametric EQ.
Pitch-shifter and an effect with eight separately adjustable bands. Suitable for altering the characteristics of the audio signal.
Low and Mid knobs adjust the cross/cutoff frequency of the bands 1-8. Such as: first band stops at 300 Hz, the next band starts at 300Hz, or (after adjusting) the first band stops at 150Hz and the next band starts at 150Hz.
Filter A has two parameters to adjust.
Setting the first adjust of filter A to zero (fully left) disables the filter.
Setting the adjust of Filter B to zero (fully left) disables the filter B.
Len A and Len B adjusts the length parameter of the effect. A is for the lower frequencies, B is for the higher frequencies.
Shift adjust for bands 1-6, the bands 7 and 8 have a single adjust which is opposite for the band 8.
At middle there is no frequency shift, downwards/left the frequency is shifted down and upwards/right the frequency is shifted up. The maximum adjust may be set to 4X lower or higher or 2x. The adjust is also available as octaves: 1 Oct, 2 Oct, with this option the shift is done as semitones, 12 semitones makes one octave.
Gain/loudness is adjusted two bands at a time. At fully left or fully right both bands are muted (no sound), at middle both bands are audible. To adjust balance of the two bands set to between left/middle/right.
LFO adjusts to vary the shift of the bands with slow oscillation (going up/down). First four LFO knobs adjusts the amount of LFO shift, at fully left the bands 1-2, 3-4, 5-8 are not LFO adjusted.
LFO Rate knobs adjust the rate/frequency of the oscillation.
'Fade' knob adjusts the sound of the pitch-shifting effect, often should be set to between left and middle.
'Tune' adjusts tuning parameter of the pitch-shifting.
'Feedback' directs output from the effect to the input of the effect, creating a feedback loop effect. This parameter can increase audio loudness noticeably.
This effect has some delay/latency, with long latency there can be over a second delay between audio input and audio output. To reduce this latency:
- Set maximum shift from 4X to 2X (or from 2 Oct to 1 Oct).
- Reduce Len 1 and Len 2 parameters.
Quality button, to reduce audio quality but reduce computation time, in case of interruptions (too slow to process in realtime).
Stereo/Stereo Wide/Mono/Mono wide button, also reduces computation time and sets to mono/stereo mode. Wide creates an stereo image (difference between left/right channels).
Preset button (p1,p2,p3 or p4).
Default (recommended) is p1.
Presets vary the LFO shape, p2 and p3 are synced separately with different EQs.
Filter, can be set to either lowpass mode (cuts out high frequencies) or to highpass mode (cuts out low frequencies). Click and drag to adjust the position of the point. Width (X) controls frequency point (in Hz), Height (Y) controls Q / resonance of the filter (amplifies the signal near the frequency point).
Alter phase of the signal with a LFO.
Reverberation type effect.
Set room size with Small/Medium/Large select and size adjust knob.
Width adjusts both stereo spread and high frequency damping.
Detune adds detuning to the reverberation effect.
Predelay parameter adds a time delay before the reverb signal.
EQ knob to adjust the two cutoff frequencies of the EQs (Low, Mid, Hi).
Freeze button freezes the reverb until clicked again.
A new reverberation effect added in version 7.4 (2014).
More adjustments and often finer sound than with the plain 'Reverb'.
Unlike 'Reverb', 'Reverb Fade' is suitable for transitions/fading: Fading an audio file to a reverberation with dry/wet (and gain) knobs, either manually or by adding as an effect to an edited transition in the transition editor.
Set room size with small, medium, large select and with breadth and remodel knobs.
Breadth may be right-clicked to freeze the reverberation until right-clicked again.
Girth adjusts stereo spread and damping of high frequencies.
Predelay adds a delay between the input signal and the reverberation signal.
Attune adjusts amount of variance, when attune is set to 0 (fully left): mod, undermost, shrill and iteration have no effect.
Mod adjusts amount of detuning and variance.
Undermost amplifies varied lower frequencies.
Shrill amplifies varied higher frequencies and low-cut filtering.
Hover, to the left: reduces low frequencies (other than shrill), to the right: reduces low frequencies (other than shrill and undermost).
Gain for adjusting output loudness of the reverberation signal (use with dry/wet knob).
Treble amplifies higher frequencies.
Iteration, adjusts variance repetition with 'Mod' knob.
'Main' sets detuning mode of the reverberation, other types than 'main' are experimental.
Quality B, C, D, E, F:
B is best quality, F is lowest.
C is not lower quality than B but just sounds different.
Quality C is the default.
Quality setting reduces computation time but alters the sound of the reverberation, although the altered sound is not only due reduced quality but just simplified, depending on the setting.
'Pres' to select one of three default presets, unlike the S|M|L select and detune select, this only adjusts the visible parameters and not the internal method of the reverberation.
This is not an actual effect but is a connector the player tempo/rate controls, it has no visible controls. Only functional when added to the transition editor or to Compile Layers: layers, as the effect editor in the transition editor/comp has dynamic points adjustment to adjust the tempo/rate parameters on a timeline.
"Tempo Con" has a hidden parameter 'Rate down' that is connected to rate control of the decks A/B and can be used to create a vinyl-brake-stop like effect.
Effects can be added to transitions between songs where the effect parameters vary within during the transition, following parameter points created by the user. For example, transforming audio of the ending song to a large hall reverb and then mixing the fading-in song to that reverb. Transition effects are described in 'Transition Editor' topic.
This device is available for main output from 'Devices' menu and also for 'Compile Layers' device for mastering.
Audio input is first separated into three frequency band groups (low, middle, high).
Then a limiter/compression is applied for each (low, mid, high) separately. Limiter reduces audio loudness differences by dropping audio levels rapidly at sudden rises (peaks), making the overall audio louder. As the limiting is done separately for each three bands, the other bands are less affected, for example, limiting a loud bass drum sound does not alter the loudness of the middle frequencies or hihats.
'Enable' enables the device.
'Post' adds a single limiter for all three bands at the end. If the 'Post Gain' adjustment is set too loud, the audio output might distort without this option enabled.
'Setup' shows a menu to save the current setup, to load a saved setup or to reset to the default setup.
LS MS HS
Sets one or more of the bands to 'Solo' mode (other bands are muted) for better tuning of the parameters.
For the first band set to 'Solo', a group of effects is shown below this device. If the effects are not fully visible (not enough screen space), try hiding some other devices temporarily, such as enabling 'Collapsible Devices' from 'Devices' menu and then clicking triangle to hide items such as the players. The effects can be shown without setting the band to 'solo' mode by right-clicking the LS MS HS buttons instead.
The effects are available for each band separately, such as adding reverb to only the high frequencies.
First effect is reverb, second one on the right is delay, both applied after the limiter, then two equalizers, the equalizer on the left side is applied before the limiter and the equalizer on the right side is added after the limiter. Below the equalizers, are chorus/flanger and distortion which are applied before the limiter.
Low cut sets the cutoff frequency between low and middle.
High cut sets the cutoff frequency between middle and high.
Attack sets how rapidly the levels are reduced when the audio is above the set threshold.
Release sets how slowly the levels are restored after the audio is no longer above the set threshold.
Thresholds should be lowered if the audio input is too quiet.
Amount sets amount of limiting, at zero (0) no limiting is applied at all.
Low band has a post-gain adjustment.
High band has a pre-gain and post-gain adjustments, increase the pre-gain and then decrease the post-gain for a stronger high frequency limiting/compression.
Adjust the loudness of the middle band by adjusting the low and high bands and the overall post gain.
Limiter meters indicate when limiting is happening for that band. Rise the input gain (pregain) or the attack/release/threshold values for stronger limiting.
For the main output multiband limiting (from 'Devices' menu), the master loudness slider in the main mixer is applied before this multiband limiter, so it adjusts the drive of the limiting, when the multiband limiting is enabled for the main output, instead adjust the last knob 'post gain' to adjust the final output loudness to speakers.
Master loudness slider in the main mixer
