Hey,

I have created polyphonic one oscillator synth and would like to add support for multiple oscillators. Problem is that it needs quite a large number of input knobs.

I tried to make custom KUIML interface by using own params and knobs and persistent="true" attribute to make it possible to save synth settings, but I could not make persistance to work?

Also I tried PERSISTENTS_OBJECT example code, but it does not save any data to a preset XML for me:

https://www.bluecataudio.com/Vault/Skin ... ement.html (https://www.bluecataudio.com/Vault/Skins/KUIML/ref_model_persistent_objects_element.html)

Other test was made with letitmix persistance example code ( gain param with persistent=true attribute), but could not got persistance to work with this either?

https://pns.letimix.com/kuiml/ref/param (https://pns.letimix.com/kuiml/ref/param)

So could anyone please give an advice how I could store own custom user data to a preset xml files?

I do got it work with custom_param0-47 and $script_input_string0-16$ but is it possible to save own custom made params too somehow?

Best regards,

Can you maybe share some example ode with us? You should definitely be able to save any data marked as persistent in your GUI using either the persistent="true" attribute, or the PERSISTENT_OBJECTS tag.

I am not sure if I understood correctly how persistent="true" works? Does it save and restore any parameter values from preset xml file? Just like custom params works?

I am creating a synth which has table for oscillators and for one row settings looks like this, persistent is set to TRUE for all parameters but I can't save them anywhere.

There will be 10x rows so 14x10 parameters is needed and I plan to transfer this sound data as a single text string to a DSP side.
