Setting Hal parameters

I would like to change a Hal components parameter through a Python script in my Glade VCP. Is this possible?

I would like to change one of my Mesa stepgen scale parameters and since you can not connect a signal to a parameter (as far as I know) I have been struggling on how to do this. My workaround has been to add a scale component to the stepgen velocity input and connect a signal to its gain pin. But I would rather change the stepgen scale parameter directly.

Yes, using the HAL python module's function set_p you should be able to do that.
