You probably know that too, your potentiometer only has an effect on the effect, the volume or something else halfway. So you turn your poti clockwork up to half and then it doesn’t matter anymore. Now it is with my VCOs that my pulse width is really only a maximum of 1/4 turn on the potentiometer. How do I get it so that the whole turn of the potentiometer can be used? This also works with purchased modules, so we have to do that too?!?!?
I have this problem with many modules and would be very happy if I could find a solution!
I’ve already read about the resistors, but that should have a very negative effect on the linear path. what are your experiences @Dud I’ve already read about the resistors, but that should have a very negative effect on the linear path. what are your experiences @Dud and could you briefly explain to me how exactly I have to insert the trim pot at the pulse width on this layout?
Thanks @Farabide but you don’t remember the name of the thread with the guide, right?
I’m not familiar with this particular circuit but on many other synths the pwm control will have inaudible portions of its range. If you view it with a scope you can see why as the wave becomes too short to hear or eventually falls flat. The MS20 does this at both ends of its pwm range.
However, given different cv inputs and octave ranges the extra range might become useful.
The range limiting resistors might be nice in one octave range, under certain conditions, but may cut out some useful range with other settings. Definitely play with it and find out of the mod is better than getting used to the sweet spots.
This is great, not just because getting the right resistor value can involve some intimidating calculations for some, but also because the values might need adjustment later.
Saw it, raved about it, even understood it when I read it … then forgot name of it.
Searched potentiometers : not it
Searched variable resistors : not it
Stopping resistors and yet still : not it.
Thought “sod it!” And posted it. @Jos did it. The secret life of pots
There : said it.
Sorry @fredrik, always worry when using exclamation points that it sounds sarcastic or confrontational. Nothing could be further from the truth my friend. We cool?
I’ll deal with that in more detail tomorrow. Thank you very much for that, that’s really great of you! @lookmumnocomputer Look Sam! Just LOVE in our forum!
Success !! My pulsewidth potentiometer now works the entire way. As @Dud suggested, I simply built a trimpot in between and used it to determine the size of the resistor I used afterwards. Thanks again for that!
