K3 Utility and LP-Bridge - Correction

[N8LP]

I have been corresponding recently with Dick Dievendorff about this. I
am looking into allowing K3 Utility to work through LP-Bridge. The issue
has to do with K3 Utility needing to be able to change one of the meta
commands in the K3, which is normally blocked by LP-Bridge to prevent
multiple applications from independently changing meta commands which
might conflict with other apps.

If I do this, it will add a check box for the VPort where K3 Utility is
connected, and I would still strongly recommend that flashing of new
firmware NOT be done through LP-Bridge.

While setting up LP-Bridge, I assumed the the K3 Utility would work ok as
"Test Communications" worked ok, and the firmware page was showing my
versions.  But I have found other functions do no work.

Looking at the LP-Bridge page I found this.

"Some commands are intenionally blocked altogether. For this reason, the K3
Utility should not be used with LP-Bridge."

Mommy always told me to read the manual first. :>)

That said, my previous posts on using K3Util with LP-Bridge are incorrect.

Thanks Larry,

By the way, since I already had a Presonus Firebox, I am using it for the interface to the LP-PAN. I did find a mod (100K resistor), while poking around the unit, that lowers the spur about 20db.

If you or anyone else has interest, I will try to find the picture I took and give details. The spur is still visible with pre-off and att-on, but with pre-on and att-off, it is below the noise.

That said, I haven't recorded into the Firebox, so I don't know if the mod had any negative effect on the audio input. My guess would be no.
