Dear dev,
Thanks for the amazing tool you've created, as far as I know OSC/Midi ipad apps have not been revolutionned since your work, hope you'll get back to it ...
BTW you say you're busy, can you tell us with what? just curious !

1) So I got sync problem with OSC out from Max... I changed the port without success, it seems to create feedback ( i don't know much about protocoles osc syncin but the inertia of synced nodes was diminished and sometimes laggy),

2) When i change app, from Touch OSC to Konkreet, KP sends all control when getting back to its page, (which i don't want , so i gate the refreshing message before and use bank up msg to refresh cos unfortunately the page number message comes after the controls refresh followed by bank up).

3) i noticed a bug when inverting nodes parameters on controll panel, it sends the right OSC value, but it stays inverted when listening...
maybe i'm doing smth wrong...?

Thanks a lot for your replies

Hi oust,

Thanks for your message and the kind words. Indeed, Marc & I are very busy with our newer projects at the moment.

Marc is at https://heartbeat-med.de

And I'm at http://basslet.de

Regarding the specific questions:

1. Feedback is often a problem with bidirectional communication. We designed Performer that as soon as you touch a node, it will go into sending mode and ignore incoming messages (otherwise it would be impossible to control). Sync problems often depend on how the two sides work together: if one side can be a "master" that helps. If both sides have a kind of inertia then everything can get very confused. Maybe share more details of your set-up and we can see what would be possible...

2. What's the exact problem? Can you just ignore the page/bank message at the other side? Unfortunately, sending out these messages is currently hard-coded in Performer.

3. Just so I understand: you invert the parameter in Performer and it sends out the inverted value correctly, but incoming OSC is still non-inverting? If so, I think that's a bug on our side! Did I understand correctly?

Regards from Berlin,

Dear Gwydion,
Thanks for your reply,
I'm surprise how cool but far your work can be from music control programmation, because your work with KP is really a hit! you are masters !
I'm using a voltage card control to modulate PWM in order to manage speed of fire rotative sirens to play music with
I output 14bits midi from max to control it, so i got 16000 step of definition in my control input.
For that i need another app (Touch osc to with increment decrement possibilities) to fine tune and be more precise than KP or any fader can be.
Basically i run Touch Osc and KP in parallele modifying the same patch and i created kind of bridge to update the values from one controller to the other when changing.

1) My feedback problem with connecting KP osc input to output is that i loose the glide of the inertia, as you said once moving node, output is inactive to prevent feedback,
but using inertia makes the assigned node stops when droped whereas no- assigned nodes continue gliding
( i solved it creating a store function that output the value only when using the other soft)

2) if there was a message saying "update" when switching app i could block the following control send from kp, to import/update my osc values from the other soft, and sync nodes with what i ve done in touch osc.
now i'm obliged to prepare switching in touch osc ( blocking kposc input), then changing KP page to use bank up value message to reopen the gate

3) i tchecked again and when inverter parameter of lenght in KP, sending the osc value to KP needs to be inverted in max msp... which is surprising to me..;

thanks for your advices!
