I'm trying out OSC (using TouchOSC, hey if it's good enough for Dave Vorhaus...) but can't get it to control a module. Connection works and Wren receives messages (the 'r' lights up) and log shows stuff like:

2021-03-28 22:09:21:627 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.555569291114807)

But I suspect I'm not formatting the message correctly. I'm trying to control the frequency control of the SVF filter module, which I've renamed @SVF. My synth name in general settings is wren. I've tried frequency, Afrequency, freq,svf_frequency for the knob names and SVF and svf uncapitalized....what's the correct message to send here?

/wren/svf/svf_frequency is the correct one .. but I see there are a couple issues with value conversions and addressing strings that I am fixing now ..

after fixing the correct string will then be /wren/svf/frequency .. as that svf_ prefix is not too useful ...

Will post here when I've made a new release ..probably today.

Ok, a new version is avalable from https://bluehell.nl/wren/ - it may still mangle OSC messages from other applications, but Wren to Wren works okay now ... so let me know please if there are issues with other apps.

Cool, thanks for the quick release! I've been testing and this is what I've found:

TouchOSC sending to Wren

Log looks like:
2021-03-29 19:07:11:925 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.425161242485046)
2021-03-29 19:07:11:938 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.429520905017853)
2021-03-29 19:07:11:956 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.430266559123993)
2021-03-29 19:07:14:422 [AUDIO ] stopping PortAudio, patch "velocity_control_simplified"

Result: no change to frequency


Wren (synth name Magpie) sending to Wren

Log looks like:
In Magpie debug log:
2021-03-29 19:10:19:818 [OSC_MSG ] OSC msg out: /wren/svf/frequency f( 0.296875)
2021-03-29 19:10:21:688 [OSC_MSG ] OSC msg out: /wren/svf/frequency f( 0.296875)
2021-03-29 19:10:23:566 [OSC_MSG ] OSC msg out: /wren/svf/frequency f( 0.296875)
2021-03-29 19:10:25:436 [OSC_MSG ] OSC msg out: /wren/svf/frequency f( 0.296875)
2021-03-29 19:10:27:315 [OSC_MSG ] OSC msg out: /wren/svf/frequency f( 0.3125)
2021-03-29 19:10:29:185 [OSC_MSG ] OSC msg out: /wren/svf/frequency f( 0.71875)
2021-03-29 19:10:31:063 [OSC_MSG ] OSC msg out: /wren/svf/frequency f( 0.71875)
2021-03-29 19:10:32:846 [AUDIO ] stopping PortAudio, patch "2021-03-29 18-52-15 01"

In Wren debug log:
2021-03-29 19:10:19:818 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.296875)
2021-03-29 19:10:21:688 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.296875)
2021-03-29 19:10:23:567 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.296875)
2021-03-29 19:10:25:436 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.296875)
2021-03-29 19:10:27:315 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.3125)
2021-03-29 19:10:29:185 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.71875)
2021-03-29 19:10:31:063 [OSC_MSG ] OSC msg in : /wren/svf/frequency f( 0.71875)
2021-03-29 19:11:04:033 [AUDIO ] stopping PortAudio, patch "velocity_control_simplified"

(note those debug logs are not perfectly synced in the cut and paste, because I didn't stop the run at the same time)

Result: no change in frequency

I'm attaching the Wren patch to confirm I have the SVF named correctly.

By the way, in the OSCMessage module in the Magpie synth patch I had to leave out the leading '/' to avoid a double forward slash in the message sent, I don't know if this is intended -- since in TouchOSC I included the leading forward slash. Maybe TouchOSC strips that when it sends the message, since I don't see it in the Wren debug.

Sorry for the double post, but I realized I didn't try the obvious thing -- renaming the SVF module to your example 'aap'.

And now it works, TouchOSC too. Too cool. Smile

Some bug matching the module name maybe?

Great that it works!

I see that in the patch you attached you named the module @SVF and from the log I see that you used svf in the addressing.

Whether OSC is meant to be case sensitive or not I do not really know (as the specs are a bit loosely formulated), but I do see sugestions here and there that case sensitivity may be intended. So I'll leave it like it is, and will make a mention of it in the FAQ.

( But why Wren would match wren then .. is beyond me Shocked )

Re. the starting slash (/) character, the specs say say that address patterns MUST start with it BUT Wren will add it to the start of the pattern by itself. I'll mention this in the FAQ.

And thank you for your feedback!
