Morphs

Morphs are snapshots of parameter values that you blend between with a single slider. Set a morph for a quiet, filtered version of a track and another for the full-blown one, and the slider takes you smoothly from one to the other — across any number of parameters and tracks. Use them for builds and drops, a DJ-style crossfade between two grooves, or a synth with 16 presets you can glide between.

Your first morph

Tap MORPH. Morph buttons A and B and the MORPH SLIDER replace the navigation bar, and the track pads turn into morph pads A–P.
Tap A and move the slider all the way left. A “P-LOCK: A” banner appears at the top: changes you make now are stored in morph A.
Change a few parameters — the filter’s Cutoff and an oscillator’s tune, say.
Move the slider to the right. The parameters glide from morph A’s values back to their normal values, because B is still empty.
Tap B and set the same parameters to new values. Now the slider crossfades between your two settings.

The slider moves every stored parameter in a straight line between its A and B values. There are 16 morphs in all, and you select them with the morph pads.

Drambo 2.0 quick walkthrough
Ben Richards
The 19-minute version of the same 2.0 tour: mute and solo, the scene fader, the clip launcher, auto-grow recording, the navigation bar, stems and the Morph module. He calls it 1.5 at the start, but it is 2.0. From May 2022.

The Morph module

The Morph module is a macro control inside a rack. It moves many parameters at once — and, unlike a normal modulation source, it can reach knobs that have no modulation input. Its amount can itself be modulated by an envelope, an LFO or anything else, and it works at sample rate.

Add Morph from MODULATOR / META.
Tap its ASSIGN button.
Turn each knob you want it to control, by as much as you want the morph to move it.
Move the module’s morph control, or modulate it — every assigned knob moves together.

It can control parameters across the track that holds it, and its menu has a Clear assigns action for starting again.

The Man Who Shouldn't Speak
The Morph module from 2.0: driving it with an LFO, envelopes or the Graphic Modulator, pointing it at several targets, and using it across tracks as a performance surface. From June 2022.

Meta randomizer

The Meta randomizer works like the Morph module, assigning many parameters at once, but it sends them to random values instead of a fixed snapshot. It is polyphonic, so each voice of each parameter gets its own value — every note of a chord can come out slightly different.

Modes

Gate random: The default: each gate on its input picks new random values.
Gate boolean: Another gate-triggered mode.
Drift: Values wander continuously, without gates — instant, polyphonic, slow movement over lots of parameters.

The Smooth knob softens the jumps between values. For a gentler mismatch between voices, like an old analogue synth, see Poly knobs in Build your own controls.

8.4Advanced

Morph Switch

Added in 2.57, Morph Switch stores a set of parameter states and switches between them. Choose a state with its polyphonic Index input, or play MIDI notes, each of which can call up its own state — like parameter locks you play from a keyboard.

Modes

Index: The Index input picks one of the numbered states.
Index X-Fade: The same states, crossfaded as the Index moves between them.
Note: Each assigned note recalls its own state, which stays after you let go.
Note Punch: The same note assignments, applied only while the note is held.

Amount scales the depth of every stored state at once, and can be modulated.
Smooth eases the change between states.
Which state plays can be parameter-locked, and note assignments can be copied and pasted.
Per-voice, sample-accurate morphing works on modulatable parameters — the ones with a small triangle beside the knob.

From the community

To play chops of one long sample from different notes, put a Morph Switch in note mode on the same track as Flexi Sampler. Turn on assign, tap a note and set the offset and loop points, then move to the next note. Copy Last speeds up consecutive chops. Flexi’s loop points aren’t truly polyphonic, so this works best one note at a time. via BeepStreet forums: There’s some things I feel ashamed to ask, October 2026

Build your own controls

The UI modules in MISC / UTILITY put controls of your own inside a rack. Each one outputs a modulation signal, so you connect it to whatever it should move. Combined with a rack’s compact view, they turn a big patch into a simple instrument (see Compact view).

XY pad: Two bipolar signals from one finger, plus a gate while you touch it. It also has a popover mode.
Knob, Knobs and Slider: Single or multiple controls for values you want to set by hand.
Buttons, Switch button and Trigger button: On/off and momentary signals.
Control panel: Eight named knobs in two columns, for gathering a patch’s important controls in one place.
Gyroscope: Signals from tilting and turning your device.
Poly knobs: One knob per voice, for differences between voices — set them to random values and use them on oscillator tune for an analogue feel.
Section (foldable): Not a control but an organiser: names a part of a long rack and lets you fold it away.

Any of these can be MIDI-mapped, so a hardware knob can drive a whole morph or randomiser. See MIDI learn. All of them are listed under Controls and displays.
