k2k audio The Parameter Panel switches view depending on your selection. Three distinct contexts, three different sets of controls.
Pad Parameters
What it controls Sound design for a single pad — the tone, timing, and character of every hit that pad triggers.
When you’d open it You’ve loaded a sample into a pad and want to shape it before sequencing: tighten the start point, pitch it down an octave, roll off some high end, or add a volume envelope so it breathes.
Quick example
- Select pad 3 in the pad grid.
- Set Trim Start to 0.12 and Trim End to 0.65 to isolate the body of the sample.
- Enable the filter, choose High Pass, and sweep Cutoff up to 400 Hz.
- Drop Pitch by 7 semitones.
- Pull Pan to -40 to seat it left of center.

Track Parameters
What it controls Sequencer behavior for one track — its clock speed, groove feel, sync relationship, and how page groups cycle.
When you’d open it You want track 2 running at eighth-note triplets while track 1 stays on sixteenths, or you need track 5 to shuffle with exponential swing at 35%.
Quick example
- Select track 4 in the track row.
- Set Clock Divider to 1/8 Triplet.
- Raise Swing to 30% and switch Swing Curve to Exponential.
- Set Group Playback to Increment with 2 loops per group so the track cycles through its groups automatically.
Parameters

|---|---|---|---|
| Clock Divider | Step duration relative to the master clock | Whole, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64, 1/4 Triplet, 1/8 Triplet, 1/16 Triplet, Dotted 1/4, Dotted 1/8, Quintuplet, Septuplet | 1/16 |
| Swing | Timing offset on even-numbered steps | 0 — 50% | 0% |
| Swing Curve | Shape of the swing offset | Linear / Exponential / Sinusoidal | Linear |

Step and Substep Parameters
What it controls Per-step triggering conditions and per-substep articulation — velocity, pitch, pan, timing, probability, effect sends, and more.
When you’d open it You’ve activated a step and want to split it into a 4-hit roll with decaying velocity, or you need step 9 to fire only every third loop with a filter sweep.
Quick example
- Click step 5 to select it.
- Set Substeps to 4.
- Choose the Ratchet preset to get a rapid-fire decay.
- Raise Dice on substep 3 to 60% so it drops out unpredictably.
- Set Effect Send A1 on substep 1 to 80% for a reverb wash on the first hit only.
