Changing your sound card: best practices in v5?

PostTue May 04, 2021 3:22 am

I've used a FocusRite Saffire with my Hauptwerk installation since I put together my 3-manual, 8 channel system some years ago. Now, it's time to upgrade as the Saffire no longer is supported and MacOS no longer has support for 32-bit apps.

I've purchased a Behringer U-Phoria UMC1820 to replace the Saffire.

My question is simple: what is the best practice for upgrading your sound card in v5? The setup is simple: three speaker pairs for the three manuals, another pair plus a subwoofer for the pedals, so routing is straightforward.

Hello Peter,

There isn't really anything fiddly or involved in changing an audio device (provided that a MIDI ports isn't also changed/renamed) -- basically you just select the new interface/driver and its channels on the 'General settings | Audio device and channels' screen. Hauptwerk will prompt you and show that screen automatically if it finds that your previously-selected audio device is no longer present, and/or if it finds that a new audio device is present. Definitely don't attach or detach any audio, MIDI or USB devices whilst Hauptwerk is actually running though.

It's always good practice to use 'File | Backup ...' in Hauptwerk before changing anything, just for good measure.

If I was in your situation I'd probably do it as follows:

- Run Hauptwerk.

- Use 'File | Backup ...'.

- Exit Hauptwerk.

- Detach your old device.

- Install the latest version of the driver for your new interface.

- Attach the new interface.

- Launch Hauptwerk.

- Select the new device and channels on the 'General settings | Audio device and channels' screen (which Hauptwerk will show automatically after prompting you that the previously-selected device isn't present and that a new one has been found).

However, the one other important thing to bear in mind is that if you were also using the Saffire for MIDI, or if you have USB-MIDI devices that might get renamed by the operating system when connecting/disconnecting USB devices, then with Hauptwerk v5 you might potentially need to reconfigure all your MIDI settings due to any previously-used MIDI ports having been changed/renamed.

[In Hauptwerk v4/v5 MIDI settings were stored relative to the MIDI port names that they related to, and if a MIDI port that you are using was changed/renamed then your previous MIDI settings for it would no longer work, and you would potentially need to auto-detect/reconfigure the MIDI settings for it for all relevant virtual controls for all of your organs again. Hauptwerk v6 handles MIDI ports differently in order to address that, whereby MIDI settings are stored relative to virtual/aliased MIDI ports (e.g. 'Console MIDI IN 1') instead of MIDI ports' device names, so that in v6 you simply need to change which column is ticked for the relevant row on the MIDI ports screen in that situation. That's covered in more detail in the list of v6.0.0 changes in the release notice ( https://www.hauptwerk.com/documentation/ ) and in the 'General settings menu: MIDI ports' section in the main Hauptwerk user guide (page 160 in the v6.0.2 version).]

Hence if there's any risk of any MIDI port names being changed or renamed then I would instead recommend:

- Upgrade your existing installation to Hauptwerk v6.0.2. (If you currently have perpetual licence for the v5 Advanced Edition then you would need to buy this upgrade and apply activate the resulting v6 licence in iLok License Manager: https://www.hauptwerk.com/upgrade-advan ... perpetual/ , then download and install v6.0.2 itself.)

- in Hauptwerk v6, specify meaningful 'user aliases' for any 'Console MIDI IN/OUT' rows that are currently ticked on the 'General settings | MIDI ports' two screen tabs, according to what MIDI hardware is currently connected to them.

- Use 'File | Backup ...'.

- Exit Hauptwerk.

- Detach your old device.

- Install the latest version of the driver for your new interface.

- Attach the new interface.

- Launch Hauptwerk.

- Select the new device and channels on the 'General settings | Audio device and channels' screen (which Hauptwerk will show automatically after prompting you that the previously-selected device isn't present and that a new one has been found).

- If any MIDI port names have changed, on the 'General settings | MIDI ports' screen (which will also be shown automatically if any MIDI devices have changed) make sure that intended MIDI ports (columns) are (still) ticked in the appropriate 'Console MIDI IN/OUT' rows (the rows for which you would have specified meaningful aliases above, so as to help identify them more easily).
Best regards, Martin.
