# ACP Volume Control for ToLiss A320 (X-Plane 12) - Skalarki Hardware ACP Required
Turn your hardware Audio Control Panel into real, working volume
controls for your PC - built and tested with a **Skalarki** ACP.
Maybe it´s working with other hardware ACP panels too, but not tested
## What it does
This plugin reads the live position of each ACP rotary (VHF1, VHF2,
VHF3, HF1, HF2, INT, CAB) on your hardware ACP - via the ToLiss A320's
`AirbusFBW/ACPxRotaryPositions` DataRefs - and uses it to control the
Windows volume of any application you choose, per channel.
A typical setup:
- **VHF1** -> xPilot
- **VHF2** -> X-Plane 12 itself
- **VHF3** -> Discord (including two simultaneous instances, e.g. main +
PTB)
You're not limited to that - assign any of the 7 channels to any running
application, or even multiple applications at once.
## Important: Skalarki Hardware ACP required
This plugin is built for users with a **physical Skalarki Hardware
ACP**. The ToLiss A319/A320/A321 cockpit does not include its own
mouse-wheel manipulator for the volume DataRefs - VHF1/VHF2 only
respond to the mouse in very coarse steps, and VHF3/HF1/HF2/INT/CAB
don't respond to the mouse at all. This is a ToLiss limitation, not
something this plugin can change. With a hardware ACP connected and
driving the DataRefs, all channels work smoothly and reliably.
## Key features
- Live volume display for every ACP channel in the plugin's status
window, with a visual progress bar per channel for an at-a-glance
overview, not just numbers.
- DataRefs are found automatically once the ToLiss A320 is loaded - no
manual "re-search" needed, even if the aircraft was already loaded
when X-Plane started.
- A simple dropdown lists every currently running application with
audio, so you don't need to remember exact process names.
- Optional quadratic volume curve for a more natural-feeling volume
taper.
- Configurable update interval and raw value range, in case your
hardware ACP uses different scaling.
- Free and open for everyone to use.
## Requirements
- X-Plane 12
- ToLiss A320 (A319/A320/A321)
- XPPython3 (free)
- A Skalarki hardware ACP, with the JPP plugin (including its
`Toliss-ACP-A319_A320_A321.lua` script) installed and running - see
the installation guide for details
## Installation
Just run the installer and follow the wizard - it finds your X-Plane 12
folder automatically and copies everything into place, including the
one-time aircraft folder fix required by XPPython3. No manual copying
needed. The only thing you have to install yourself is the JPP plugin
with its matching Lua scripts, since that's what connects your Skalarki
hardware ACP to X-Plane in the first place (see Requirements above and
the installation guide).

This tool is free, but if it made your cockpit a little nicer to fly
with and you'd like to support continued development, you can leave a
