dsp-setup-switch

Switch the active sound setup on Audiotec Fischer ACO-based DSP amplifiers (MATCH / HELIX / BRAX) over their USB connection, from the command line.

Requirements

• Python 3.8+
• pyserial
• The amplifier connected via USB (it enumerates as a USB serial device)

Setup (virtual environment)

Create and activate a virtualenv, then install the dependency:

macOS / Linux

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Windows (PowerShell)

py -m venv .venv
.venv\Scripts\Activate.ps1
pip install -r requirements.txt

Later, reactivate with source .venv/bin/activate (macOS/Linux) or .venv\Scripts\Activate.ps1 (Windows) before running the script. Deactivate with deactivate.

Tip: to run without activating, call the venv's Python directly, e.g. .venv/bin/python set_setup.py 1.

Usage

python set_setup.py <slot>

<slot> is the setup memory number, 1–10.

python set_setup.py 1     # switch to setup 1
python set_setup.py 5     # switch to setup 5

The amplifier is auto-detected by its USB vendor id. If you have several serial devices, name the port explicitly:

python set_setup.py 1 --port /dev/tty.usbmodem101   # macOS / Linux
python set_setup.py 1 --port COM5                   # Windows

On success the script prints the setup before and after the change and confirms the switch:

/dev/tty.usbmodem101: setup 7 -> 1
OK - now on setup 1

Notes

• Tested with a MATCH M 5.4DSP on macOS.
• The amplifier holds up to 10 setups; only slots you have actually configured will switch.
