Pressure In

Unipolar per-note pressure, with channel aftertouch broadcast to all active voices.

What it does #

Pressure In supplies polyphonic pressure or MPE pressure independently for each voice. If the source sends only channel aftertouch, Bitwig applies that shared value to every active voice on the channel.

Controls and ports #

Control	Label	Official description
out	Out	Unipolar note poly pressure signals received by the device (or if channel aftertouch is received, those values are applied to all voices)

Practical uses #

• Open a filter or add vibrato independently while pressing individual keys.
• Use channel aftertouch as a common expressive layer when poly pressure is unavailable.

Things to know #

• The nominal domain is 0 to 1.
• Poly pressure can differ per note; channel aftertouch cannot.
• Pressure is continuous after note-on and is not interchangeable with initial velocity.

Technical details #

No Nitro implementation has been confirmed for this visible module. The behavior is described conservatively from module metadata and editorial research.

The host maps pressure to a per-voice unipolar scalar. Recovered Note Out code clamps the inverse output expression to [0,1] with default 0. Event rate, interpolation, and channel-aftertouch fan-out are host-side and not represented by a dedicated Nitro body.

Open questions #

• Measure update rate, smoothing, poly-pressure and channel-aftertouch precedence, release, and voice stealing.

Version and sources #

Checked against Bitwig Studio 6.0.6. This page combines Bitwig's module metadata, the existing Grid course and guides, and Nitro analysis where the mapping is strong enough to support a technical statement.
