Send 0 after curve finished

[Masen]

Hi,

I’m new to Iannix, I’m working on a piece and have a problem.
The piece is basically a score with many curves and a global linear timeline to scan all curves at once.
I’m sending the Y-Value of a curve to a PD-Patch where each curve controls a OSC with the Y-Value representing the frequency in Hz.
This is working quite well, what i need to do is – when a curve is finished – scanned to an end, it should send out a 0, so that the OSC stops generating sound… How can i managed that?

Thanks and best regard
Damian

Hi!

First, thanks for using IanniX :). Then, it’s a common problem that we never solved because it’s not so easy to create the right solution.

Maybe the best thing would be to put a trigger just at the end of the curve, this trigger can send “fake” cursor values (=> double-clic on the trigger to change its message, then select “Default OSC Message for cursors” and edit values). Is it an acceptable solution?

[Masen]

thank you for your answer!
I thougt about triggers, but it will be around 300+ curves, adding the same amount of triggers makes it quite a huge project 😉
But if there isn’t a “automated” solution, I think I will have to do so…

[IanniX]

And what about making that in PD => for each abstraction of each curve, if no frequency update during 40ms (eg.), stop the oscillator (as we did in our Max patch)?

Hi,

I will try this… Which example are you talking about, the Max Sound Example? How do you exactly managed that gate?

Thanks.

[IanniX]

Yes, the “gate” is in the poly~ subpatch (synthetizer.maxpat), using the adsr~ object to release gain after xxxx ms of inactivity

[Masen]

Thanks, this worked Out! Even a delayed triggerd 0 had worked, but with a ADSR the Release can fade it out… Thanks again!

[IanniX]

Nice!

[Masen]

Yes I’m very happy, the conecert is in less than a month, now I’m glad everything is working as planned 🙂

Thanks alot again! 🙂
