All tools Mixing & Transitions

Mixing tools for cleaner transitions and better-shaped buses

Mixing is mostly decisions about geometry — when does this track start, where does the EQ split live, how much should the sidechain duck, which curve shape fits this build-up. These five tools give you the diagrams so you stop making those decisions by ear alone. They won't replace the ear, but they will catch the mistakes your ear misses after hour six of a session.

Two Decks

Mix Point Planner

Two parallel timelines with your planned overlap drawn between them. Computes the exact bar & beat where deck B should drop in, and shows the EQ-split shape of your crossfade (linear / log / EQ-curve) so you can see whether the swap will feel like a smooth wash or a clean cut.

Unique: warns if the transition would end before B's first downbeat, and shows the "EQ handover" — which frequencies each deck owns at the midpoint.

Bezier Editor

Automation Curve Editor

Drag bezier handles on a canvas to design volume / pan / filter / send curves. Pick a preset shape (linear, exponential, log, S-curve) or sculpt your own. The tool exports the result as a plain-text list of points and as a CSV — drop either into your DAW's automation lane.

Unique: shows the underlying math expression (e.g. y = a + (b - a) * (1 - (1-t)³) for ease-out cubic) so you learn the language of curves, not just the knob.

Bode Plot

Filter Sweep Visualiser

Pick a filter type (LP / HP / BP / Notch), a cutoff, a resonance value and a sweep length. Two canvases draw the frequency response (Bode plot) and the gain-over-time curve in real time. Watch how resonance creates an audible peak before the filter self-oscillates.

Unique: suggests a kick-friendly cutoff (≈ BPM / 4 Hz) so your sweep "sits" where the kick lives instead of fighting it.

Meter Strip

Gain Staging Helper

Enter an input level and stack the plugin chain — the tool shows a vertical meter strip with cumulative gain through every stage and a red flag if you've stacked enough +dB boosts to clip the master bus. Suggests target ranges per instrument (kick, vocal, bass, master).

Unique: includes a small plugin-trim calculator for parallel / NY-compression paths where the parallel bus usually needs a different level than the dry signal.

Envelope

Sidechain Ducking Calculator

Set your source level, target reduction, attack and release. The tool draws the duck envelope over time and tells you what percentage of each bar the source will be ducked vs audible. It rates the result on a "pump feel" scale (subtle / pumping / extreme) so beginners know whether their settings match their genre.

Unique: shows the relationship between release time and BPM — if release > 1 beat at 128 BPM, your source will never fully recover before the next kick.

A typical mixing workflow

1. Lay out the bus structure in Gain Staging — pick targets per instrument before you touch a fader.
2. Shape the transition with Mix Point Planner or Filter Sweep if the build-up calls for one.
3. Sculpt the automation with Automation Curve Editor — export to your DAW.
4. Add motion with Sidechain Ducking, dialing the envelope to a "pump feel" that matches the genre.

FAQ

Why does my crossfade sound like a volume dip instead of a smooth handoff?

Linear crossfades divide energy equally at the midpoint, which means both tracks sit at –6 dB at the same moment — your ears read that as a dip. Try an EQ-style crossfade (deck A fades out on the highs while deck B fades in on the lows), or use the Mix Point Planner to design the curve shape.

How long should my sidechain release be at 128 BPM?

At 128 BPM, one beat is 469 ms. For a pumping-but-not-mushy sound, release between 100–250 ms. The Ducking Calculator will tell you if your release is too long to recover before the next kick — that's the most common beginner mistake.

Can the Automation Curve Editor replace Ableton's envelope editor?

No — it's a planning tool. It generates the shape of the curve and exports it as values, but you'll paste those into your DAW to actually drive the parameter.

What is "pump feel" supposed to feel like?

For EDM listeners, "pumping" means the bass ducks visibly with each kick — the source level drops enough that you can see the gap in a meter. For more natural material (pop, indie, folk) you want "subtle" — the duck is just enough to clean up the low end without drawing attention.
