3. General Improvements
3.3 - MIDI
- ([#47]) Extra MIDI ports on the USB interface for MPE. Port 2 shows in the midi device menu, and improves the usability of MPE-capable devices through the USB interface by allowing MPE zones to be sent to port 2 and non-MPE to be sent to port 1 (or vice versa). A third port is added for future use such as a desktop/mobile companion app, DAW control or Mackie HUI emulation.
3.4 - Tempo
- ([#178]) New option (FINE TEMPO in the Runtime Settings (Community Features) menu) to invert the push+turn behavior of the "TEMPO" knob. With this option enabled the tempo changes by 1 when unpushed and 4 when pushed (vs 4 unpushed and 1 pushed in the official firmware). This option defaults to OFF.
- This feature can be turned ON/OFF in the Runtime Settings (Community Features) Menu (accessed by pressing "SHIFT" + "SELECT").
3.5 - Kits
- ([#395]) Load synth presets into kit rows by holding the audition pad and pressing synth. Saving kit rows to synth presets is not yet implemented.
3.6 - Global Interface
- ([#118]) Sticky Shift - When enabled, tapping shift will lock shift on unless another button is also pressed during the short press duration.
- ([#118]) Shift LED feedback can now be toggled manually.
3.7 - Mod Wheel
- ([#512]) Incoming mod wheel on non-MPE synths now maps to y axis
4. New Features Added
Here is a list of features that have been added to the firmware as a list, grouped by category:
4.1 - Song View Features
4.1.1 - Master Compressor
-
([#137]) In the Song view, select "AFFECT ENTIRE" and "SIDECHAIN" modulation button, and adjust the upper gold knob. Push the upper gold knob to switch to the next setting (Threshold (dB), Makeup Gain (dB), Attack (ms), Release (ms), Ratio, MIX). The LEDs next to the knob act as a gain reduction meter.
- This feature can be turned ON/OFF in the Runtime Settings (Community Features) Menu (accessed by pressing "SHIFT" + "SELECT").
4.1.2 - Change Row Colour
- ([#163]) Pressing a "CLIP" row + "SHIFT" & Turning Vertical Encoder ▼︎▲︎ changes the selected row color. This is the same shortcut like before when setting the color in the clip view.
4.1.3 - Fill Clips
- ([#196]) Holding the status pad (mute pad) for a clip and pressing select brings up a clip type selection menu. The options are:
- Default (DEFA) - the default Deluge clip type.
- Fill (FILL) - Fill clip. It appears orange/cyan on the status pads, and when triggered it will schedule itself to start at such a time that it finishes at the start of the next loop. If the fill clip is longer than the remaining time, it is triggered immediately at a point midway through. The loop length is set by the longest playing clip, or by the total length of a section times the repeat count set for that section. Limitation: a fill clip is still subject to the one clip per instrument behavior of the Deluge. Fill clips can steal an output from another fill, but they cannot steal from a non-fill. This can lead to some fills never starting since a default type clip has the needed instrument. This can be worked around by cloning the instrument to an independent copy.
4.1.4 - Catch Notes
- ([#221]) The normal behavior of the Deluge is to try to keep up with 'in progress' notes when instant switching between clips by playing them late. However this leads to glitches with drum clips and other percussive sounds. Changing this setting to OFF will prevent this behavior and not try to keep up with those notes, leading to smoother instant switching between clips.
- This feature can be turned ON/OFF in the Runtime Settings (Community Features) Menu (accessed by pressing "SHIFT" + "SELECT").
4.1.5 - New Grid Layout
- ([#251]) Add new grid session layout to "SONG" mode. All functionality from (classic) row layout applies except for the following:
- The data model of rows and grid mode are compatible, you can switch between them freely
- In grid mode you will not be able to see multiple clips that are in the same section, only the first one. To make them visible move the clips to other sections
- The colored coloumn on the right are all available sections, the columns are automatically filled with the tracks in the same order as in arrangement mode
- In session mode hold "SONG" and turn "SELECT" encoder to switch between row layout and grid layout
- Existing clips (dimly white or green) can be opened by holding "CLIP" button and clicking on them
- New clips can be created by holding "CLIP" button and clicking on an empty pad. If the column was empty a new track is created
- By quickly clicking (and releasing) populated pads you can change the arm state
- If "SHIFT" is held at the same time the clip will launch immediately
- If "RECORD" is held at the same time you can change recording status
- If "HORIZONTAL ENCODER" ◀︎▶︎ is held at the same time you can change solo state
- By holding a populated pad you can see the track, change the parameters and convert it to other instruments similar to rows layout
- Hold an existing pad and press on another pad in the same, other or empty row to copy clips. If possible the content will be converted to the target track type
- To delete a clip hold the pad and press the "SAVE/DELETE" button
- To arm a whole row click on the section color to the right
- To immediately switch to a whole row hold "SHIFT" and click on the section color
- To MIDI learn:
- Arming a section hold "LEARN/INPUT" and hold the section pad
- Arming a clip hold "LEARN/INPUT" and hold the clip pad
- Note input to a track hold "SHIFT" + "LEARN/INPUT" and hold the pad of any populated clip for that track
- Compared to rows layout the following is not supported
- Overdub recording
- Copying clips to arranger
- Copying audio clips between different tracks
- A new menu to select the default Layout has been added in Shift+Selection Encoder -> Defaults -> UI -> Song -> Layout
4.2 - Clip View - General Features (Instrument and Audio Clips)
4.2.1 - Filters
-
([#103]) Adds a new filter in the low-pass slot, a state-variable filter. This filter has significantly less distortion than the ladder filters, think sequential vs. moog. Cutoff and resonance ranges are subject to change with further testing.
- Follow-up PR's: ([#125] and [#212]) Various SVF fixes
-
([#336]) Morphable and Driveable Parallel Filters
-
Add an SVF option to the HPF slot, set for HPF mode by default. This can be modified through the menu, shortcuts, or clicking the lower knob while HPF is selected.
-
Follow-up PR: ([#339]) SVF Notch Filter
- Adds an SVF notch mode (SV_Notch) alongside the SVF Band mode (SV_Band)
- Changes SVF morph in HP slot to go HP-band/notch-LP (HP by default)
- Tweaks default ladder saturation to match original firmware
- Applies ladder gain on input instead of feedback, avoiding interaction with resonance
- Tweaks SVF level to match ladder volumes
- Removes distinction between high and lowpass SVF enums so they can now be used in either slot
adds HP ladder morph to filter FM
-
Adds a 3rd filter paramater called morph, placed in the menu and on the pads under the db/oct on filters. Morph smoothly morphs the SVF through LP-BP-HP, and smoothly increases drive in the ladder filters. This param is modulatable and automatable
-
Adds a setting to switch the filter order or run them in parallel. This setting is menu only and named ROUTE
-
4.2.2 - Stereo Chorus
- ([#120]) New Stereo Chorus type added to Mod FX. The recommended settings are OFFSET=30, DEPTH=17, and RATE=15.
4.2.3 - MIDI Takeover Mode
This mode affects how the deluge handles MIDI input for learned CC controls.
-
([#170]) A new takeover submenu was created in the MIDI settings menu which consists of three modes that can be selected from:
1. Jump: This is the default mode for the Deluge. As soon as a Midi Knob/Fader position is changed, the Deluge's internal Knob position/Parameter value jumps to the position of the Midi Knob/Fader.
2. Pickup: The deluge will ignore changes to its internal Knob position/Parameter value until the Midi Knob/Fader's position is equal to the Deluge Knob position. After which the Midi Knob/Fader will move in sync with the Deluge.
3. Scale: The deluge will increase/decrease its internal Knob position/Parameter value relative to the change of the Midi Knob/Fader position and the amount of "runway" remaining on the Midi controller. Once the Midi controller reaches its maximum or minimum position, the Midi Knob/Fader will move in sync with the Deluge. The Deluge value will always decrease/increase in the same direction as the Midi controller.
4.2.4 - Alternative Delay Types for Mod Encoders (Golden Knobs)
-
([#282]) Ability to select, using a Community Features Menu, which parameters are controlled when you click the "DELAY"-related golden knobs. The default (for upper and lower knobs) is PingPong On/Off and Type (Digital/Analog), and you can modify it so the knob clicks change the Sync Type (Even, Triplets, Even) and Sync Level (Off, Whole, 2nd, 4th...) respectively.
- This feature can be turned ON/OFF in the Runtime Settings (Community Features) Menu (accessed by pressing "SHIFT" + "SELECT").
4.2.5 - Patchable Wavefolding Distortion
- ([#349]) Adds a pre filter wavefolder, and the depth is patchable/automatable. The depth is accessible in both the menu and on the pad between saturation and LPF cutoff. The fold has no effect when set to 0 and removes itself from the signal path.
- Note that it has no effect on square waves, it's best with sines and triangles
4.2.6 - Quantized Stutter
-
([#357]) Ability to set, using the Community Features Menu, the stutterer effect to be quantized to 4th, 8th, 16th, 32nd, and 64th rate when selecting it. Once you have pressed the Stutter knob, then the selected value will be the center value of the knob and you can go up and down with the golden knob and come back to the original rate by centering the knob (LEDs will flash indicating it).
- This feature can be turned ON/OFF in the Runtime Settings (Community Features) Menu (accessed by pressing "SHIFT" + "SELECT").
4.2.7 - Grain FX
-
([#363]) New Grain FX type added to Mod FX. This effect is somewhat resource-intensive, so please use only one instance per song.
-
Parameters:
- Mod Depth: Controls Grain Volume / Dry Wet Mix
- Mod Offset: Adjusts Grain Size (10ms - 800ms)
- Mod Rate: Sets Grain Rate (0.5hz - 180hz)
- Mod Feedback: Selects Grain Type
-
Grain Type (Presets):
- Preset 1: Unison and +1 Octave (Reverse)
- Preset 2: Unison and -1 Octave
- Preset 3: Unison and +1 Octave (Defalut)
- Preset 4: 5th and +1 Octave
- Preset 5: Unison and +1/-1 Octave (Tempo Sync)
-
This feature can be turned ON/OFF in the Runtime Settings (Community Features) Menu (accessed by pressing "SHIFT" + "SELECT").

4.3.4 - Fill Mode
- ([#211]) Fill Mode is a new iteration/probability setting for notes. The FILL setting is at the start of the probability range, before 5%. Notes set to FILL are only played when fill mode is active. There are two ways to activate FILL mode - set it as a Global MIDI Command and/or set it to override the front panel Sync Scaling button. For Global MIDI Commands go to SETTINGS > MIDI > CMD > FILL. To override the Sync Scaling button set SETTINGS > COMMUNITY FEATURES > SYNC to FILL. The orignal Sync Scaling function is moved to SHIFT + SYNC-SCALING.
4.3.5 - Automation View

4.5.2 - Unison Stereo Spread
- ([#223]) The unison parts can be spread accross the stereo field. Press "SELECT" in the "UNISON NUMBER" menu to access the new unison spread parameter.
4.5.3 - Waveform Loop Lock
- ([#293]) When a sample has loop start and loop end points set, holding down loop start and tapping loop end will lock the loop points together. Moving one will move the other, keeping them the same distance apart. Use the same process to unlock the loop points. Use "SHIFT" + turn "HORIZONTAL ENCODER" ◀︎▶︎ to double or half the loop length.
4.6 - Instrument Clip View - Kit Clip Features
4.6.1 - Keyboard View
- ([#112]) All-new use for the "KEYBOARD" button in kit clips, uses the main pad grid for MPC-style 16 level playing. Horizontal encoder scrolls by one pad at a time, allowing positioning drums left to right, and vertical encoder jumps vertically by rows.
- Follow-up PR: ([#317]) Fixed the issue where audition pads would remain illuminated after pressing pads 9 to 16 and then returning to the Clip View.
4.6.2 - Drum Randomizer / Load Random Samples
- ([#122]) Pressing "AUDITION + RANDOM" on a drum kit row will load a random sample from the same folder as the currently enabled sample and load it as the sound for that row. Currently limited to 25 files for performance reasons.
- This feature can be turned ON/OFF in the Runtime Settings (Community Features) Menu (accessed by pressing "SHIFT" + "SELECT").
4.6.3 - Manual Slicing / Lazy Chop
-
([#198]) In the Slicer view, press the Horizonal Encoder ◀︎▶︎ knob. When you press the green pad in the bottom left, it starts playing the first slice, and pressing an empty pad creates a new slice. Turning the Select knob to the left or pressing the Pad + DELETE button allows you to delete a slice.
-
Turning the Horizontal Encoder ◀︎▶︎ knob allows you to adjust the start point of the slice. Additionally, turning the Vertical Encoder ▼︎▲︎ knob transposes the slice.
-
Follow-up PR: ([#210]) Changed to stop audio preview (played by the sample browser) when entering manual slicer mode.
4.6.4 - Batch Delete Kit Rows
- ([#234]) While you can delete a kit row by holding a Note in a row and pressing "SAVE/DELETE", the "Delete Unused Kit Rows" feature allows you to batch delete kit rows which does not contain any notes, freeing kits from unused sounds (which take some precious RAM). While inside a Kit, hold "KIT" and press "SHIFT" + "SAVE/DELETE". A confirmation message will appear: "Deleted unused rows". This command is not executed if there are no notes at all in the kit.
- This feature can be turned ON/OFF in the Runtime Settings (Community Features) Menu (accessed by pressing "SHIFT" + "SELECT").
