tiar/delay/over1tap, over3tap and over5tap
See the help patches: Menu Help -> Library -> community -> tiar -> delay

-> over3tap and over5tap : chorus examples
For my string machine i needed some nice chorus effect.
The usual delay lines introduce a variable low pass filter due to linear interpolation.
The trick I use here, consists internally oversampling the delay line so that the "reader" interpolation low pass filter effect would be less prominent.
The over1tap, over3tap and over5tap are single and multitap delays with internal x2 oversampling.
The "Over" attribute can change the type of internal oversampling.
- "Smooth" : "equalised" low pass input for a vintage sound
- "Normal" : the usual scheme with its drawback (variable LP filtering)
- "Bright" : optimal FIR filter for a modern sound
They are handy for chorus and flanger designs.

Note: the delay controls d1... d5 are internally interpolated and smoothed (1st order LP) at audio rate.
