Volume control glitch

Hi,

I have building with Reaktor for some time. Mostly customising others work, but I have done a few synths in primary. However a problem I've come across with a lot is having smooth level control. I am currently building an instrument with a few sampler tracks and individual volume controls for each channel. Previously I have used the studio mixer instrument in the Factory Library in such cases, but I wanted to have everything in one instrument.

The problem is, whenever I turn the volume knob, I hear a glitchy sound. As if the volume is raised gradually in steps rather than smoothly and continuously. I am now using the 'add' module for volume control. I tried using the 'amp/mixer' module as well, but both had the same problem.

Does anyone have any ideas as to what I'm doing wrong? As far as I can tell, using the 'add' module is pretty usual way of implementing volume control.

Here is a screenshot from my build:

 

OK. Somehow asking these things always helps in problem solving! I just realised that the volume knob was sending at control rate, while amplitude should be controlled at audio rate. Adding an 'audio smoother' after the knob and before the 'multiply' module solved the problem. I feel like a real tool, not figuring this out sooner.

I am still wondering whether there is a simpler solution to this, or if my workflow should somehow be better (I really don't have workflow, I just add stuff and see whether it works).

 

Nope, that's exactly the way to do it.
