Speed variable Table Play? noob questions

alexk · 2015-09-29 14:07:41 UTC

Hi - I am thinking about a pitchable sample playback object and want to use the table/read or table/play object as a basis, but not sure which one makes more sense to attempt to modify.

Table/read needs an input slope to run through the table and normally I use a Phasor Compl object before it but that needs a triggered start and just one cycle. I failed to modify the Phasor object correctly. I also tried using an ADSR but it doesn't seem short enough. I guess I could try to feed in some sort of converted envelope and perhaps modify that to have a more exact range.

Table/Play I hope can be modified with a parameter that could perhaps increase of decrease the playback.

which do you think makes more sense?
I ask since I think making a phasor a single cycle with a trigger feels like overkill.

Just pushed an object to the git repo for pitched table playback. Care to test?

alexk · 2015-09-29 14:58:37 UTC

pff awesome. Works!
only the knob seems to do the opposite (lowers pitch when increased). But maybe that is correct.

Yeps, would like to test....

Is the send program change also to be found on git repo.? Found it Awesome

alexk · 2015-09-29 15:06:49 UTC

playback of table/play seems a bit louder than the pitchable one.

thanks a lot for the help!

anon5189335 · 2015-09-29 15:16:23 UTC

I downloaded it and put it in my object folder with the other wave player objects, but when I open Axoloti and look for it, it is not there... Is there something special I have to do, to make the visible in objectbrowser?

alexk · 2015-09-29 15:17:00 UTC

yeah you gotta reload objects from the File menu dropdown in the main axo window

anon5189335 · 2015-09-29 15:27:27 UTC

Hmm. I get this message. It is almost all red text. Neither the pgm change out object or any of the play pitch objects are visible in the browser. Any other tips for making them visible? I am probably doing something wrong since none of the objects i tried to copy to objects folder work.

I copied the pitch objects to the table folder here:
/Applications/Axoloti.app/Contents/Java/objects/table

and then Reload objects.

I am on Mac, BTW.

no probs with the new table objects.
make sure you open a new window for the editor.

(and clean up those duplicate hash objects hah)

anon5189335 · 2015-09-29 16:22:32 UTC

I Reloaded the objects and opened a new editor window and they are just not there....

They are still not there after restart Axoloti software.

Actually none of the objects I copied manually to the objects folder have worked... The blend4 object, any of the pitch objects and also not the pgm out object. I cant see them in object window for some reason. Any ideas? I am on Mac

About cleaning up hash objects: How do I do that?

anon5189335 · 2015-09-29 16:53:45 UTC

@alexk which OS are you using, BTW? WIndows, OSX?

johannes · 2015-09-29 17:01:43 UTC

That knob adjusts the reference pitch of the sample. So it is on purpose.

anon5189335 · 2015-09-29 17:12:19 UTC

@johannes

Any advice on making objects visible in the object window? What Alex tells me doesnt seem to work.

johannes · 2015-09-29 17:22:55 UTC

How did you download the .axo files? I guess they're mangled somehow. Check with a text editor.

anon5189335 · 2015-09-29 17:45:43 UTC

I right clicked and "save link as". First I saved as text format, with no luck. Now I tried same procedure, but save as all files, so it should be same format... But that didnt work either.

johannes · 2015-09-29 17:53:22 UTC

If you download it from the github website: navigate to the file, right-click->save link as on the "raw" button.

anon5189335 · 2015-09-29 18:11:25 UTC

YES That worked. Thanks @johannes

It looks awesome. But I cant compile a patch with the play pitch loop object. I get this error:

And I get this when reloading objects:

What is that hash object issue? Almost all objects I have added manually has that issue. Non of them work.

alexk · 2015-09-29 18:16:34 UTC

you will need to copy paste those suggested hashes into the .axo object

johannes · 2015-09-29 18:24:38 UTC

You're not supposed to reference a wave file in the "play pitch" object but the instancename of a table/alloc... object.
There is also a help patch provided on github.

The hash mismatch: probably different line ending characters. Should not cause malfunction.
