Hi All,

i have build a controller/programmer for the great DIY Hardware subtractive VA Synth XVA1 from René Ceballos.
The controller sends 7bit SysEx strings to the unit from every knob or button, based on the parameters specified in the documentation of the project.

Details about this great project can be found under https://www.futur3soundz.com/

The controller/programmer works for me as an exe and vst3 instrument in Cubase or Reaper.
Still trying to figure out some issues with MIDI CC, but midi-learn from within the DAW works well incl. automation events recording.

I now want to dump the factory presets from the EEPROM by sending the dump command.
I did the needed to read and convert the dumped sysex values to match with the FS float values. (0-1)
But i did not figure out how to hold the extracted value for a single parameter.
The knob keeps to be updated when a "false" is met. (Parameter ID not met)

Can someone please have a look. It might be something very simple i havent thought of.

As i have build the controller with the Alpha of FS to be able to use it with my main DAW Cubase i only attach here the main knob sending SysEx and the Dump approach i have hooked up. Rebuilt with 3.0.8.1 Skylark.

Many thanks !

Cheer, Neptune

P.S. In case you dont see the knob labels please install fonts Lato and Bastion on your machine.

Hi Neptune,

The select prim will send the FALSE value everytime it receives a false from the boolean input, and the TRUE value everytime it receives a true trigger from the boolean input.

As I understand it, you only want to update the knob once, when parameter ID is X, with the parameter value that's present at that time. If that is correct, you want to work with the prims boolean to true trigger (resp. boolean to false trigger). They will only trigger once. But in my example, you have to make sure, that the parameter value is loaded, before the parameter ID is loaded, or else it will fill the knob with the previous parameter value.

Remember, this is just a tip to push you in the right direction, I'm sure you will face other issues further on, that we don't think of now.

Good luck!
Unfortunately I only have 3.0.6 and the alpha installed, so I had to save with the alpha.

Thank you so much Tulamide!
