Mixer
Sum up to 32 channels, each with gain, pan, mute and solo, into one mix with a master level. Plug a cable in to add a channel.

Blend an editable list of up to 32 audio channels. Plug a cable into + Channel or onto the card to create a channel, or add an empty one and wire it later.
What it does#
Each channel has its own input, gain, pan, mute and solo. A durable channel ID names its input and controls: channel.in, channel.gain, channel.pan, channel.mute and channel.solo. The master level follows the sum. Mute beats solo; when any channel is soloed, only soloed channels are heard. Solo is saved and automatable.
Drag a channel's grip to reorder it, or drag it off the card to remove it. Reordering, names, colours and icons affect presentation only; cables and Frame controls continue following the same channel. Undoing removal restores its controls and cables.
When to use it#
Combine sources into one mix, make a subgroup, or build a desk with mute and solo. For a single balance between two sources use Crossfade.
Ports#
| Port | Direction | Signal | Lanes |
|---|---|---|---|
channel.in | Input | Audio | Inferred from the cable |
audio | Output | Audio | Inferred from the cable |
Parameters#
| Parameter | Label | Range | Default | Unit | Scale | Notes |
|---|---|---|---|---|---|---|
master | Master | -60 to 12 | 0 | dB | linear | Mix output level in decibels, after every channel. −60 dB is off; 0 dB leaves the sum unchanged. |
channel.gain | channel Gain | -60 to 12 | 0 | dB | linear | Level of this channel in decibels. −60 dB is off; 0 dB leaves it unchanged. |
channel.pan | channel Pan | -1 to 1 | 0 | linear | Position on a two-lane mix: −1 left, 0 centre, 1 right. Constant-power for a one-lane channel, balance for a two-lane one; ignored on other widths. | |
channel.mute | channel Mute | 0 to 1 | 0 | linear | Silences this channel. Mute beats solo. Choices: 0 On, 1 Muted. | |
channel.solo | channel Solo | 0 to 1 | 0 | linear | While any channel of this Mixer is soloed, only soloed channels are heard. Choices: 0 Off, 1 Solo. |
channels: 0–32 items, each with a durableidand optionalname,color,icon. Item order affects presentation only; ports and controls use the item ID.
Tips#
- −60 dB is off. Start each source quietly and leave headroom at
master. - Mono channels use constant-power pan into a stereo mix; stereo channels use balance with unity gain at centre. Pan is ignored on other widths.
- Channels may have an optional name, colour and icon. Their IDs stay stable when renamed or reordered.
- Use Alt (Option) Solo in the Mix drawer for exclusive solo.
