Wraps the host ASIO sound card inside a Usine module: picks the active driver, exposes its sample rate and buffer size, reports the available channel counts, and feeds the ASIO buffers into Usine's audio engine.
The module hosts a single instance of the system-wide ASIO driver. It enumerates every ASIO driver installed on the machine, lets the user pick one from a combo box, and forwards the driver's audio callback to Usine's internal audio dispatcher (doAudioDeviceIOCallback). It also surfaces the driver's sample rate, buffer size and channel counts, and provides a button to open the vendor's native control panel.
It is the audio I/O backbone on Windows ASIO setups — typically a single instance lives at the top of the workspace and routes the sound card to the rest of the patch.
Note — this is a system-level module: only one ASIO driver can be active at a time, and changing driver / sample rate briefly stops the audio engine while the host re-creates its buffers.
Combo box listing every ASIO driver detected on the machine (built from the system's ASIO registry). Selecting an entry deactivates the current host, switches to the new driver, syncs Usine's sample rate / buffer size / channel counts with it, and re-activates the host.
If a driver allow-list is configured in Usine's setup (asiodrivername key), drivers whose name does not start with the allowed prefix are rejected: the audio callback is silenced and an error is traced. This is the protection used on dedicated installations (e.g. branded Adamson rigs) to make sure only the validated sound card is used.
Button. Opens the active ASIO driver's native control panel — that's where vendor-specific settings (sync source, clock, channel routing, etc.) are configured. The panel is owned by the driver itself; Usine just calls into it.
Combo box with the supported rates: 44100, 48000, 88200, 96000, 176400, 192000. The selector reflects the driver's current rate and lets the user change it. Switching rate stops the host, applies the new rate, rebuilds the audio buffers, refreshes Usine's settings, then restarts the host. If the driver runs at a rate outside this list, the combo box displays no selection.
Current ASIO buffer size in samples. The value is editable (range 32 – 2048); editing it requests a new buffer size from the driver, which may round it to the nearest supported value. The actual size returned by the driver is written back to the control. Buffer-size overrides are persisted per driver + sample rate pair in Usine's setup, so the same combination reopens with the same size next time.
Read-only. Number of input channels exposed by the active ASIO driver. Updated on every driver / sample-rate change.
