Panning tool
I´v got a little battle horse I´d like to share.
Taking in count the Haas effect and the real diferences of sound when the source moves side to side, I took a few days and developed a windows vst, it adjust delay, eq and level (all in the same knob). Far away more realistic than a regular pan-pot (level only).
It obviously works on stereo channels only, but you can route mono signals to stereo mixing channels in most of programs.
I also added the posibility to name instances to get a clear workflow using multiple instances.
Be aware when you use it and then convert to mono, it can add Hi frequency comb filter but not much. All the way to one side adds 0.4 ms to the opposite side, at that point the level diference doesn´t let you hear the comb, so the comb filter it´s going to be generated from 0.3ms to 0 increasing the effect as sides equals level (in case you take your stereo mix to mono later).
For windows users of the forum:

For install just paste the panning.dll file in to your vst folder

Don´t you think that big programs should include this simple pann-pot aproach(delay, eq and level conbined) as a default option?
