The Mixer

The Mixer gives you one channel strip per pad so you can balance levels, set stereo position, and quickly isolate or silence pads while you build a beat.

Opening the Mixer

Tap the slider icon in the top-left toolbar of the Pad Grid. The mixer opens full screen with all sixteen channel strips arranged in two rows — pads 1–8 on top, pads 9–16 below — so the layout mirrors the grid. Each strip is labelled with its pad number and accent color, and shows the loaded sample’s name. Empty pads appear dimmed.

When you are done, tap Done to commit your changes and close the mixer. Volume and pan moves are applied live as you drag, so you can mix while the sequencer is running.

The Channel Strip

Each strip contains, from top to bottom: a volume fader, a level meter, a pan knob, and M / S buttons.

Control	What it does	Range / default
Volume (fader)	Sets the pad’s playback level. The fader reads out in dB next to the track, showing -∞ at the bottom.	0 to 1 (linear), default 1.0
Pan (knob)	Positions the pad in the stereo field. The label below reads C, L/R with a percentage.	-1 (full left) to +1 (full right), default 0 (center)
M (mute)	Silences the pad.	On / off
S (solo)	Isolates the pad.	On / off

Mute and Solo

Tapping M mutes a single pad. Solo works across the whole mixer: as soon as any pad is soloed, every pad that is not soloed is effectively muted. You can solo more than one pad at a time — they all play, and the rest stay silent. Clearing all solos returns every pad to its own mute state. A strip that is silenced by either rule is shown dimmed so you can see at a glance what is and isn’t sounding.

Level Metering

Each strip has a vertical peak meter beside the fader. It is color-coded so you can spot hot signals: green for normal levels, amber as you approach the top, and red near the ceiling. Meters fall back smoothly after each hit, so a quick transient stays readable. Metering runs only while the mixer is open.

Master Output and Output Routing

The mixer balances individual pads; the project also carries a single master output level that the pads sum into. The combined signal then passes through the master effects chain.

Routing each pad to an output bus is handled in the pad’s properties, not in the mixer. Open a pad’s properties and find the Output Routing section, where the Output Bus picker offers:

Bus	Behaviour
Main	Pad runs through the master filter / reverb / delay.
Group 1–Group 4	Pad bypasses the master effects and emits dry.

In the standalone app all five buses are summed back to your main stereo output, so group assignments still play through your speakers — they simply skip the master effects. The bus you choose is saved with the project, so the routing carries over when GranSample runs as a plugin. See GranSample as an AUv3 Plugin for host setup.
