Topic: Bug in micGain analog channels 1-8 with OSC on UFX+

TMFX v 1.93 MacOS (3)
RME Thunderbolt Settings Firmware: v112, Driver: v1.05
Fireface UFX+ (23919669) (the old hardware version, I guess: SW Version: 55, Active Nodes: 105
OSC: host: 127.0.0.1, port 9000 (outgoing), port 8000 (incoming) set in Options > Settings: Tab OSC in TM FX.

If you turn the mic gain dial in analog channels 1-8, which has a range from 0 to 12 dB, and which can be set in 0,5 dB steps in TotalMix FX, you receive all 25 different values over OSC.
If you send the same values back over OSC, you can only select the mic gain in 1 dB steps, though it will respond to al the 25 different values.
Unfortunately it is not some sort of rounding that happens to the resulting dB value in TM FX.
For instance: 5 dB can be set with 3 different values, 0 dB with 2 values, and 9 dB with only 1 value (as it should be).
But, for instance, setting 9,5 dB is impossible.
The fact that TM FX can send the values, means that TM FX should be able to receive them as well, unless I'm missing something not so obvious... (yes, almost everything else works, but I'll post another bug report about that).

If you don't have Max/MSP, I've made a screenshot, but it seems impossible to add it to this post.
(Yes, I've seen the buttons at the top, I've read the online explanation, but the image does not show in the Preview of this topic).
If someone can explain me what to do to post an image, I'll upload it.

If you have max/msp, you can test it with the following patcher.
If you want, you can try max for free for 30 days.

Let me know if you can replicate this behavior.

Re: Bug in micGain analog channels 1-8 with OSC on UFX+

This bug I found yesterday has the same kind of issues: https://forum.rme-audio.de/viewtopic.php?id=38877

Re: Bug in micGain analog channels 1-8 with OSC on UFX+

We don't call these bugs but 'compatibility limitations'. I explained this already here:

https://forum.rme-audio.de/viewtopic.ph … 85#p175885

We do have customers with custom OSC solutions, even hardware mixers, that will no longer work correctly when we start to change our OSC implementation. Basically OSC needs to be device specific, as newer devices have extended and additional functionality. We might do this at a later time, though.

Re: Bug in micGain analog channels 1-8 with OSC on UFX+

This is not about the maximum level. I've already read that post.
I understand the issue with device specific values.
I've not only read the manual, I've also read most topics about OSC on this forum.

The bug is not being able to set values that end with ".5".

Repairing this bug should not limit any implementation, since it is impossible to set these values, so no implementation will exist that can set them.

The values can be sent from TM FX. So TM FX "knows" these values.

How to test: set the mic gain on channel 1 to 0.5 dB.
receive the value on /1/micgain1
It is 0.007692

Now send the value 0.015385 on /1/micgain1 to TM FX over OSC.
The button on analog channel 1 is now on 1.0 dB.
Now send the value 0.007692 on /1/micgain1 to TM FX over OSC.
The button on analog channel 1 SHOULD now BE 0.5 dB, but it is 0 dB.

Conclusion:
- this does not have anything to do with device specific values.
- this cannot break any implementation

Non of the OSC bugs I've reported have anything to do with device specificity, so please look at all my posts about OSC bugs.
It takes time to test and write these bug reports...

Please test this and see what happens.

Thx!

Re: Bug in micGain analog channels 1-8 with OSC on UFX+

Any results?

We will start working on TM FX soon.

Re: Bug in micGain analog channels 1-8 with OSC on UFX+

Great!
I've tested all OSC messages and have no new bugs to report.

Re: Bug in micGain analog channels 1-8 with OSC on UFX+

Should be fixed in TM FX 1.96 beta 4.

That's great! I will test this on a later date.
