K-Follow

oddson · 2 Mar 2006

I have to admit I don't know what a K-follow is... but you've got string data instead of floats being attached to stream maths... I don't think that works (in fact integers didn't work in some versions of SM)...

edit - confirmed it doesn't work... but integers now do

I will look at that

Key-follow You can change the Cutoff variation for lower to higher note with a knob.

I could see it followed the keyboard (given the schemtaic and the names) but coulndn't guess what for...

Maybe I'm getting confused with something else but I thought the filter in the example synth had key-tracking/key-follow?!

Shif.

It does. The standard SVF has a setable pitch tracking amount.

Key track and Key follow are not the same. Key track modify the filter curve and K-follow modify the Cutoff freq depending on the note your playing on a keyboard.

Try my Adventus synth to see what the key track and K-follow do. http://www.softplug.com/download.html

turn the k-follow left and lower note have more Cutoff, turn right and it's just the opposite.

Hm. I don't see the difference. What do you mean by "modify the filter curve" ?

The SVF only has positive "k-follow" (or pitch/key tracking as I like to call it), but that is easily extended to work for negative tracking values as well.

But. What do you mean by "Key track modify the filter curve" ?

I don't understand either 😮 😉

I may be wrong with that, but i feel that the ADSR respond differently as you move the k-track knob. For you, what the key track really do?

It sets how much the initial cutoff frequency follows the pitch of the current played note. With "filter curve", did you mean filter ADSR curve?

Yes

Never heard of any key tracking that alters the filters ADSR... So I think that by "K-follow" you mean the same thing as the rest of us, just that you use a different term 🙂
