EFFECTS ALGORITHMS 00-19 PLATE REVERB REVERB & CHORUS Simulates the old reverb device of the same name. It generated reverb by playing sound through a small speaker on one end of a 6-foot by 4-foot plate of steel with a transducer on the other end to pick up the reverberated sound. This reverb is excellent for vocals and Drums. 20-29 ROOM REVERB Simulates various room sizes. Excellent for guitar and vocals. 40-49 HALL REVERB Similar to the Room, but is a simulation of a larger room. The high ceilings, irregular shapes and the uniform density of the reflections characterize Halls. REVERB PARAMETERS RA- Reverb algorithm selection (choose Plate, Room, or Hall). PL1-Plate algorithm #1 PL2-Plate algorithm #2 - thinner, tighter sound HA-Hall algorithm ro1-Room algorithm #1 ro2-Room algorithm #2 - brighter, more open sound ADDITIONAL PARAMETERS RF- Input band width limit allows you to select the frequencies you would like to accentuate with the reverb. (Example: Accentuating the high frequencies will give you a very airy open sound. Accentuateing low frequency on a bass drum gives an ideal reverb effect.) RP-Pre-delay is a slight delaying of the reverb so that the original signal stands out easily from the reverb. RD-Decay time determines how long the reverb will sound before it dies away. Adjust this to create "long-tail" reverb RH-Reverb damping alters intensity of the reverb for a darker or brighter sound. 50-54 Triangle Choruses. Triangle The Triangle Chorus is an sharp edged chorus used for clear sounding acoustic guitars and background vocals. 55-59 Sine Wave Choruses. Sine Wave The Sine Wave Chorus is a smooth sounding chorus excellent for thickening lead and background vocals and great for lead and rhythm guitar. CHORUS PARAMETERS r1-Oscillator 1&2 Speed How fast the frequency cycles are. d1- Oscillator 1&2 Depth. Fd-Feedback Determines the amount of signal fed back through the processor. Adds harmonic richness. LF-LFO(low freq. oscillation) select - triangle or sine r1-Oscillator 1 Speed r2-Oscillator 2 Speed d1-Depth Oscillator 1 d2-Depth Oscillator 2 Fd-Feedback 11
