Hello Eric,
To add to Mark's reply, yes -- the behaviour of those virtual LEDs indicate for master mix bus 1 is normal and correct. (All three would be lit by default because the blower sounds constantly, but without the blower blue would be lit, and red and green should light up whenever you play stops/keys, indicating that sound is going into the mixer bus, and out of it to your selected audio device channels.)
The only things I can think of to suggest (with St. Anne's loaded in your spare 'alt config N') are:
- With master mix bus 1 selected, try different values for its "
Audio output (device) channels: Channels" setting in the right-hand pane, in case some of your AudioFire channels are working and not others, for some strange reason.
- On the "
Audio, MIDI and Performance" large control panel, check that the audio signal level meter shows activity when you play stops/keys. If so, it indicates that the driver is correctly calling Hauptwerk to calculate audio.
- Maybe try turning up the "Trim dB" on that control panel (e.g. to 0).
- Since the AudioFire was desupported by Echo a long time ago, and may not be fully compatible with more-modern software (e.g. Hauptwerk v5+ is linked to more recent versions of Microsoft's Windows libraries than v4 was), see whether the freeware ASIO4All driver (
https://www.asio4all.org/ ) works, instead of Echo's ASIO driver.
Failing that, I think you might indeed have to replace the AudioFire with something modern, I'm afraid. The MOTU 24ao units are certainly popular amongst Hauptwerk users, and well-regarded.
Best regards, Martin.
