Not a true delay, but a fade-in; works well in most cases. This
example creates a delayed vibrato effect. LFO edit: m1>lfo1,0%. Lfo
rate 5-6 hz. Mod matrix: mod routing 1: lfo1(sine)>voice pitch
narrow, level +1.6%. Mod routing 2: P/M envelope>lfo1 amplitude,
level +100%, offset -100%. P/M env edit: attack 1596ms. Attack
slope -exp. Decay .5ms. Sustain level +100%. Sustain time hold.
Release 2ms. The envelope attack time adjusts the LFO fade-in time.
To make the LFO fade-in, then fade-out, set env sustain level to 0%,
then use decay time to adjust the LFO fade-out time.
