The pioneer EFX-500 had an amazing delay and it would be great to have these features.
1) stepped increment delay:
1/1, 3/4, 1/2, 1/4, 1/16 this is better than the knob so you can pick exactly which delay length you want. Currently in the knob you’re guessing what the right interval is.
2) filtered delay so to all High-pass, mid-pass or low-pass.
the combination of the 3/4 delay with the high pass filter is a timeless sound but hard if not impossible to replicate in Traktor.
this feature request is to add it to the main effects section and to Mixer FX so the delay grows and the filter sweeps as you turn the dial.
