I have been trying to implement spat5 into my pattrstorage system but so far it is not working. Am I missing something or simply spat5 is not designed to work with pattrstorage (if this is correct… too bad!)?
I know snapshots work, but how can I call those from outside spat5.oper? Maybe this way I can link it to my pattrstorage system.
What are other ways to save presets? Documentation is not very helpful on this topic.
Best,
JM
Hi JM,
I’m aware of these issues, and I’m sorry for the inconvenience.
Proper pattr support (along with improved documentation) is ready for the next release (currently under tests).
This should hopefully ship next week.

Hi Thibault,
I have ran into the same issue with pattrstorage again. I can store 1 preset in a json file, which allows me to use it when loading it, but it doesn’t seem possible to recall more than one preset.
Has this issue been dealt with?
Many thanks
Coralie
Hi Coralie,
Have you looked at “spat5.tuto-osc-2.maxpat”, tab “pattr” ?
Annoyingly, you need to send the “/pattr/store” message before storing the preset; other than that, I believe things should work. Otherwise, feel free to send me additional information.
Best,
T.
Hi Thibault,
My mistake, I had suppressed the viewer from my patch.I am in parallel using spat5.oper.
Will there a possible conflict between both objects?
Thanks!
No, there should be no conflict between objects.
But you need to send the “/pattr/store” message to all (spat5) objects that you want to pattr-ize.

Doesn’t seem to work with ircamverb

Apparently ircamverb~ has issues or specificities I haven’t yet understood concerning pattr.

Hi Roland,
In spat, pattr is supported only by GUI objects.
So, you should pattr-ize spat5.ircamverb rather than spat5.ircamverb~.
Let us know if this makes sense for you.

Hi Thibaut,
I’m just working on my Spat system to see which is the best way to store the spat5.oper states. I’ve done a simple working system with snapshots that allows me to filter out all the “parasite” parameters during performances (the window states, zoom and source focus, etc.).
Now, I’m am also testing a system based on pattrstorage to see if it’s better or not. I’ve seen that the spat5.oper is stored as a dictionary and I have two questions:
-
How can I read/access the content of the dictionary (I’ve tried to use spat5.from.dict or to.dict…or collect but perhaps I’ve not understood the format)?
-
I remember all the problems using pattrstorage in the “old spat4 times”, when recalling presets from a new incremental version of Spat. As you know, the parameters where stored as a big list and if the new sub-version added new parameters, the presets were simply not recalled because the list was of a different length. The spat told something list "Received 401 atoms while expecting 405)…So, my question: is it reliable to use pattrstorage with spat5, or will there be such problems with future incremental uptates that you would rather recommend using spat’s native presets and snapshots?
Thanks!
Hi Lorenzo,
I presume you had a look at “spat5.tuto-osc-2.maxpat” already.
The internal state of spat5 object is represented as an OSC bundle. When using pattrstorage, this OSC bundle is converted to a Max dictionary (similar to what spat5.osc.todict does).
So, basically this is equivalent to dumping the state, and storing it into a dict (as demonstrated in “spat5.tuto-dump-1.maxpat”)
Now, I dont know how to access the dictionary inside pattrstorage. This is more of a Max question, and maybe you could find info on Cycling’ forum ?
Yet, if you open your maxpat inside a text editor, you will actually see the content of the dict in the pattrstorage.
As the dict/pattr is only just another representation of OSC bundle, I believe this is a stable way to store data (does not suffer the issues we had in spat4). That should be future proof.
The main “issue” with Max pattr and M4L snapshots is that they want to store the whole state of the object whenever one parameter is changed. For spat objects that typically have hundreds or thousands of parameters, this appears extremely inefficient and impractical. Therefore the “/pattr/store” workaround which seems to work OK, but is also not super elegant/user friendly.
Hope this helps,
T.
Hi Thibaut,
yes, I saw the “spat5.tuto-osc-2.maxpat” already.
In the pasted patch, a way to display the content of spat5.oper dictionaries stored in a pattrstorage (try to memorize 2 pattrstorage slots and view their content with the dump message).
Since the presets are stored in the dictionaries embedded into the pattrstorage, the user cannot filter out the window state, position, dimension and the “focus” parameter, so for my personal practice the best way is using the spat snapshots…:
