Re: [Harp-L] Modulation effects

[Robert Hale <robert@xxxxxxxxxxxxxx>]

Vibrato and Leslie sounds ARE cool for harp because they are pitch
changes of the whole signal.

Sweeping (moving) chorus is weaker because it is cancelling (comb
filtering) some frequencies of the original full-bodied signal, and
not truly creating vibrato. Some units allow feedback to re-introduce
the filtered signal again.

Phase shifters can be set from weak, to almost approach the full
"lumpy" sound of rotary speakers.

Use "detune" for the Micky Raphael sound of tremolo/echo harps in the
Willy Nelson band. Detune by 10-15 cents, and mix 50-50. (half-step =
100 cents)

Off topic: for a real interesting head-spin, hear Shepard Tones: The
music that falls in pitch but never gets there.
