@freq63 It looks as though the metro for playback position is only on for alternate file loads.
You might want to incorporate automation of adjustment for the file samplerate to ensure correct playback speed. It is dumped by the right outlet of soundfiler..... any-samplerate.zip
That patch also adds the guard points to the [array] to ensure correct interpolation by [tabread4~] as the [phasor~] wraps.
And if you will share the patch then you should get the Pd samplerate using [samplerate~] to insert the value into [expr].

@Moothart The list-abs library has an abstraction that will confifm that a value is a member of a list.

@stefano_zorzanello Yes...... the settings are saved to the registry, and so read from the same place when opening all 64-bit versions of Pd.

Caveat.... I use the "portable" zip downloads of Pd so that I have them all available at any time.
So....... if I have installed externals to version 54.1 I still have that version on my computer and the paths are found when I open version 56.
If I then use Deken to install more externals while 56 is open then they will be written to the folders containing version 56 and new paths will need to be set.

If you "install" version 56 it will overwrite 54.1, but the externals will not be overwritten, so the paths will stay the same.

@stefano_zorzanello
Here is your file working on my computer.... hmm.zip

You can find the pd file format here........ https://puredata.info/docs/developer/PdFileFormat

Scroll down to "canvas".... for a full description.

So it seems that your edit was acceptable.
Did you edit the file in a very basic text editor?
In windows notepad works, but if you edit in a word processor you will corrupt the file with hidden formatting characters.
EDIT..... same conclusion as @oid
David.

@totoetlititi I don't see a flatpak app for 0.55.2 on the Pd 0.55.2 download page.
You can find "apt-get" versions for Linux/debian etc. here......

@ddw_music It is a little more complicated.
If you are writing a paper then you should look at @jameslo's conclusions re a previous discussion on the building of the dsp graph and the use of subpatches to control the ordering and ensure repeatability..... https://forum.pdpatchrepo.info/topic/13512/s-r-throw-catch-latency-and-object-creation-order/21
There is a lot of detailed info in the thread.... maybe nothing new for you but...?
David.

@soundproofskin Pd specific shortcut key bindings are in pd_bindings.tcl in the Pd/tcl folder.
You can change them (carefully) to have what you need, or better still write a pd-plugin file.
I don't know (as yet) how to do that correctly.

OS standard bindings seem to be in tk.tcl in the same folder and are set according to the the window system detected.

I am running windows on a Mac so a Mac keyboard. Key identifiers seem to be wrong for some modifying keys.
For me Fn+left and Fn+right jump to the beginning and end of the selected text. But I find no mention of Fn as a modifier anywhere in the .tcl files..... so...?
And the up and down arrows do the same.... jump to the beginning and end.

Sorry... not much help..
David.

@oid A recent change (since the doc was written).
https://puredata.info/docs/developer/PdFileFormat

I don't know how long ago but it doesn't work in Pd extended.
Interesting, and it persists through a save..... so is now part of the file format.
It also works for objects and even some gui's even though gui's have fields already for setting width.
David.

@jameslo Not sure..... if you are banging the slider and moving it at the same time then it is hard to interpret.
The fader can be moved by hand fast enough to cause trouble as the OP found.
Yes, certainly, if moving the slider faster than the speed that would create an output every 0.125 msecs it might not be reliable, but your test is mixing 2 effects so....?
I found that all data points were produced by my test at higher speeds than [metro 0.125] but the console print was failing.
Caveat.... was [tabwrite] still writing to the array?
I will try again at higher rates but if [tabwrite] fails to update the [array] then I will never be certain of the limit without console output.
Except that if a whole 400 point table is written it should indicate success.... unless the screen fails to update because Pd has effectively hung of course.

No idea whether cpu speed has relevance at todays speeds..... probably not.
Mine ... Processor Intel(R) Core(TM) i7-3615QM CPU @ 2.30GHz, 2301 Mhz, 4 Core(s), 8 Logical Processor(s)

David.

@jameslo Comms starts to fail with the console below about [metro 0.125] but all values are still produced by the slider........
