MIDISketch in Bitwig Studio
There are two ways to use MIDISketch in Bitwig: as the track's instrument with your synth loaded inside it, or as MIDISketch MIDI FX in front of any instrument. With the CLAP, it can also play Bitwig's own devices like Polymer, and CLAP or VST3 synths after it, with every note bending on its own.
MIDISketch as the Instrument
The simplest way. MIDISketch is the track's instrument and your synth plays inside it. The VST3 and the CLAP both work.
- Install MIDISketch from the download page. If Bitwig doesn't list it, rescan your plug-ins in Bitwig's settings.
- In Bitwig's browser, find MIDISketch and drag it onto an Instrument Track.

MIDISketch in Bitwig's browser. - Click the Synth button in MIDISketch's toolbar and load your synth, for example Vital, Serum 2 or Phase Plant.
- For per-note bends, use an MPE synth: turn on its MPE and set its pitch bend range to
48.VitalOn the Advanced tab, turn on MPE (bottom left) and set the bend range (bottom right) to
48.
Vital: (1) Advanced, (2) MPE Enabled, (3) bend range 48. Click to see it full size. - The pill at the top of MIDISketch shows its bend range. It should read MPE: 48st.

The pill, reading MPE: 48st. Synth stuck at another range? Set MIDISketch to match instead: settings gear › MIDI Settings... › MPE & PITCH › PITCH BEND. Clicking the pill opens the same tab.

MIDI Settings, MPE & PITCH tab, bend range 48. - Draw notes and pitch curves, and press play.
MIDISketch MIDI FX
MIDI FX is MIDISketch as a note effect. It goes first in the track's device chain and plays the instrument after it, with no second track and no routing. It only sends notes, so it has no synth inside and the parts that need audio are hidden.
Get It
MIDI FX comes with the MIDISketch installer, as a box you tick. It installs next to MIDISketch, not in place of it, and includes the CLAP.
Windows: choose Custom installation and tick MIDISketch MIDI FX. macOS: in the installer's list, tick MIDISketch MIDI FX for other DAWs (VST3 + CLAP). Already have MIDISketch? Run the installer again with that box ticked. Every download is also on the download page.
Set It Up
- On an Instrument Track, add MIDISketch MIDI FX first in the device chain. Take the CLAP: it keeps MPE, the VST3 doesn't.

MIDISketch MIDI FX in Bitwig's browser. - Add your instrument after it: Polymer or another Bitwig device, or an MPE synth.
- Turn on Per-note bends (below). For a VST3 MPE synth after it, also turn on Bitwig's Use MPE on its device and set PB Range to
48, with the synth's own MPE on. - Draw in MIDISketch MIDI FX and press play. The instrument after it plays every note.
Per-note Bends: Bitwig, CLAP and VST3 Synths
One switch in MIDISketch decides how it sends notes inside Bitwig. Turn it on, set up each VST3 MPE synth once, and every kind of instrument bends each note on its own. The switch is in the CLAP of MIDISketch and of MIDISketch MIDI FX, and only appears inside Bitwig.
What the Switch Does
MIDISketch sends notes in Bitwig's own per-note format (CLAP note expressions). Each note bends on its own in:
- Bitwig's devices: Polymer, Phase-4, the Grid and the rest.
- CLAP synths that support per-note expressions, such as Phase Plant.
- VST3 MPE synths, such as Pigments, but only once that synth's device has Bitwig's Use MPE switch on (step 3 below).
While it's on, MIDISketch's own built-in synth is off on that instance: the device after MIDISketch plays the notes.
MIDISketch sends standard MPE MIDI, a channel per note. That works for a VST3 MPE synth on its own, but Bitwig's devices and CLAP synths won't bend each note.
The Setup That Works for Everything
- Load the CLAP of MIDISketch or MIDISketch MIDI FX, with your instrument after it in the same chain.
- Click the settings gear, open MIDI Settings..., go to the MIDI OUT tab and turn on Per-note bends under BITWIG.

Per-note bends, shown off here: turn this on. The same switch is in User Preferences... › GENERAL as Bitwig devices: per-note.
- For each VST3 MPE synth after it, such as Pigments, Vital or Serum 2:
- Select the synth's device in Bitwig.
- In Bitwig's Inspector panel, turn on Use MPE.
- Set PB Range to match MIDISketch: the MPE: 48st pill at the top of MIDISketch shows its range,
48by default. - Turn on the synth's own MPE mode too, as always. Each synth's steps are on the synth setup page.
- Bitwig's own devices, and CLAP synths with per-note expressions like Phase Plant, need nothing else.
- Draw and press play. Each note bends on its own.
To play a device on another track, add a Note Receiver on that track and pick MIDISketch as its source. The first time MIDISketch opens in Bitwig, a one-time tip points to the switch.
Troubleshooting
One synth bends each note and another doesn't, or plays every note at one pitch
Usually Bitwig's Use MPE is off on a VST3 synth. Turn Per-note bends on in MIDISketch. Then select the VST3 synth's device, turn on Use MPE in Bitwig's Inspector and set PB Range to 48. Bitwig's devices and CLAP synths need nothing else. The full steps are above.
Notes play but don't bend in Polymer or a CLAP synth
Turn on Per-note bends in MIDI Settings, MIDI OUT tab, under BITWIG. It works with the CLAP only.
No MPE through MIDISketch MIDI FX
You loaded the VST3. Swap it for the CLAP of MIDISketch MIDI FX.
Bends sound wrong in an MPE synth
Set the synth's pitch bend range to 48 to match MIDISketch. The pill at the top of MIDISketch shows its range.
A VST3 synth stopped bending after I turned on Per-note bends
Leave Per-note bends on. Select the synth's device, turn on Use MPE in Bitwig's Inspector and set PB Range to 48. Then every instrument on the track bends each note.
MIDISketch doesn't show up in Bitwig
Rescan your plug-ins in Bitwig's settings and check that the plug-in folder is listed. The CLAP installs to C:\Program Files\Common Files\CLAP\ on Windows, /Library/Audio/Plug-Ins/CLAP/ on macOS and ~/.clap/ on Linux.
Quick Tips
- As the instrument, the VST3 or the CLAP. For MIDI FX and Bitwig's own devices, the CLAP.
- MPE synths: bend range
48, so the pill reads MPE: 48st. - Per-note bends on, plus Use MPE on every VST3 MPE synth, works for every instrument.
- Per-note bends turns MIDISketch's own synth off while it's on.
- Linux: put the CLAP .tar.gz in
~/.clap/. MIDI FX is for Windows and macOS. - Use the Standalone app to sketch ideas without opening Bitwig.
- What MIDI FX is for, and which DAWs take it, is in the docs.
