Description:
Allow any widget-driven value change (buttons, steppers, faders, radios, menus) to be applied as a
ramp
instead of an instant jump—tempo-aware, quantized, and with selectable curves—so parameters glide musically to their targets.
Problem:
Instant value jumps can cause clicks, harsh transitions, and imprecise musical moves. Today, achieving smooth, time-synced changes requires multi-step macros or external automation, which is slow to build and fragile on stage.
Proposed Solution:
  • Ramp Options on “Set/Adjust Parameter”:
-
Duration units:
ms/s,
beats/bars
,
cycle of clip X
, or
combinations
(e.g., 1 bar + 250 ms).
-
Curves:
Linear, Exponential/Log, S-curve, Step, and Bezier (with shape %).
-
Targets:
Absolute value,
Add/Subtract
,
Multiply/Divide
(e.g., ×1.5 dotted), clamp to min/max.
-
Start & Restart policy:
From current value;
Restart / Continue / Queue / Blend
when a new ramp arrives.
-
Quantize start:
None, Beat, Bar, Loop, or
Cycle of clip X
;
late-press guard
to defer if too close to boundary.
-
Sync safety:
Click-safe gain handling (auto microfade for very short ramps), sample-accurate scheduling.
  • Controls & API:
- Actions:
Start Ramp (target, duration, curve, quantize)
,
Cancel Ramp
,
Pause/Resume
,
Resync to Boundary
,
Set Ramp Policy
.
- Variables:
ramp.active
,
ramp.progress
,
ramp.remainingMs
,
ramp.target
,
ramp.curve
,
ramp.policy
,
ramp.sourceClipCycleBeats
.
- Inspector HUD: small progress ring/bar and resolved target/time readout.
  • Batch & Mapping:
- Ramp
multiple parameters
from one widget with independent curves or a shared timeline.
- MIDI/OSC mappings can request a ramp per change (with
throttle
and
delta threshold
to prevent spam).
  • Presets & QoL:
- Quick chips:
×2 / ÷2 / dotted ×1.5 / triplet ×2/3
, “2 bars”, “500 ms”, “¾ cycle of Drums”.
- Save ramp presets per widget/page; themeable success/queued feedback.
  • Conflict Handling:
- Per-parameter
lane
with policy for overlapping ramps; optional “kill others on start.”
- Safe undo groups; ramps survive page switches unless flagged “local only.”
Benefits:
  • Smooth,
    musical
    transitions without macro sprawl.
  • Reliable, bar/beat/clip-synced moves that land exactly on boundaries.
  • Fewer clicks and level shocks; cleaner live operations.
  • Reusable ramp presets speed up show programming.
Examples:
  • Delay Mix
    : ramp 0% → 35% over
    2 bars
    with
    S-curve
    , quantized to bar; late press defers to the next bar.
  • Filter Sweep
    : 200 Hz → 6 kHz over
    ¾ of the Drums clip’s cycle
    , exponential curve;
    Restart
    policy for retriggers.
  • Master Duck
    : −12 dB over
    120 ms
    , then
    Resume
    to 0 dB over
    1 bar
    when talkback released.
  • Morph Macro
    : one button ramps four synth params with different curves on a
    shared 4-bar timeline
    ; Multiply LFO rate by
    ×2/3 (triplet)
    mid-ramp.

Original Post:
Apply ramp to value change action on widgets
I am controlling my dials and faders using iPad touchscreen and I’d like to have an ability to apply ramp to value change action on widgets.
So that when I press and slide to change the value, the value gets changed smoothly, not in spurts like it’s now.
I.e. the desired behavior is: when press and slide a dial up very fast to get the highest value, the value changes smoothly within the configured ramp time, say, 8th note.
It will help with life performance dramatically.
