How can I do this distortion effect?

[Jafo]

You'll need to separate the higher frequencies (perhaps by a high-pass filter), distort the result, and mix back with the original signal. A quick and easy way to do this is to double your track in your host and do this to one track.

What host are you using? Stuff like this is REALLY simple using racks in Tracktion.

Tracktion, actually. Never bothered with racks, since I prefer to have my tracks under my control, not my host's.

Err, also, I don't know how to get Tracktion to stop applying rack effects to all tracks indiscriminately...

Not sure what you mean here with either comment.

Racks only show up if YOU put them there, not the host. In all of the various bugs which have been present in Tracktion, this is the first mention I've seen of indiscriminate racks appearing magically on tracks.

T2 now has Aux sends built in if you like - simply put a HF distortion, or a signal chain with a HP filter then distortion on the receive track.

Hmm... I've re-read my comment, and I cannot find anything which even remotely suggests racks appearing by themselves. Could you be more specific as to the source of your confusion? I did mention racks applying effects to all tracks indiscriminately when I try to use them; is this the comment to which you refer? If so, could you explain how you managed to misinterpret that as tracks "magically appearing?"

Err, sorry everybody for being a touch too acidic.

If a rack is applying effects to all tracks, you must have it in the master section. Try dragging it only to the track you want. Rockstar_not posted this decent tutorial doing this exact thing over on the Tracktion forum.

You could also use the Delta FX distortion which applies the distortion to three user definable bands: no internal routing necessary.
