Slope ↗
Bitwig Platform
A one-sided slew processor that slows rising changes while allowing falling changes to pass more directly.
What it does
Slope ↗ reshapes only upward movement. When the input rises above the current output, the output approaches it according to Time; when the input falls, the module follows that decrease without applying the same upward slew.

Time | Slew time for rising signal changes |
Practical uses
- Add attack or portamento only to rising control changes while preserving fast downward resets.
- Turn gates or steps into rising ramps with sharp falls.
- Place it after random or sequenced modulation to soften upward jumps without blurring downward accents.
Things to know
- This is not an envelope follower: it processes the signal value itself rather than first extracting amplitude.
- Only the rising direction receives the configured slew behavior.
- Successive rising targets can change the destination before the previous ramp has finished.
- The exact response may be rate-limited or exponential; the installed description alone does not establish that distinction.
Technical details
No Nitro implementation has been confirmed for this visible module. The behavior is described conservatively from module metadata and editorial research.
The behavioral contract is a one-sided smoother: if input > state, move state toward input according to Time; otherwise pass or rapidly follow the falling input. The atlas contains a generic symmetric linear slew helper using state = clamp(input, state-step, state+step), but there is no evidence that Slope ↗ is this helper with one branch bypassed. Exact curve, time normalization, initialization, stereo policy, and zero-time behavior require measurement.
Open questions
- Distinguish linear rate limiting from exponential smoothing with several step sizes and Time values.
- Measure falling pass-through, changing targets mid-ramp, negative values, zero crossing, initialization, and stereo behavior.
- Determine whether Time specifies full-scale travel, a time constant, or a settling threshold.
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.
