Notes on the Parameters

1(2) Glide Delay  (Gldlyhi) Provides (coarse) and fine adjustment of mono delay

time. This control is called Predelay (Pdlyhi)  in the Pitch/Delay , Gate and
Plate algorithms, and Delay 1 in Chorus Delay.

3

Glide Feedback  Adjusts positive feedback around the mono delay.  In
Delay/Reverb, 100% feedback does not cut the input, but continues to add
it in. There is also a slight high frequency rolloff through the gliding delay
mechanism of Delay/Reverb. In Pitch/Delay (where it is called Predelay
Feedback
), 100% feedback automatically cuts the input, and can be used
as a manual, or MIDI controlled, delay line sampler. In Chorus/Delay (where
it is called Feedback 3) it recirculates the output of Delay 1 and Delay 3
before it enters the third chorusing circuit.

4(5) Delay 2  (Dly2hi) Provides (coarse) and fine adjustment of two-channel

delay time.In Delay/Reverb, provides a predelay adjustment for the reverb.
In Pitch/Delay (where it is called Delay L (DlyLhi) ) this control provides a
reverb predelay and adjusts the left channel. In Chorus/Delay, Delay 2 adds
an additional offset to the value of Delay 1 for the second pair of chorused
taps.

6

Feedback 3  Adjusts feedback around the pitch shifter and left channel
delay. This control is called Feedback in Pitch/Delay.

7(8) Delay R (DlyRhi)  Provides (coarse) and fine adjustment for right channel

delay.

9

Pitch On/Off Used to enable the pitch shifter.Selecting 0 (Defeat) bypasses
the pitch shifter and the small delay associated with it.

10 Pitch Interval Adjusts the pitch shift from two octaves down (Pitch ON=1;

Pitch Interval=0) to one octave up.

11 Pitch Fine Provides a fine adjustment of pitch for detuning. The MIDI value

0-127 is interpreted as being centered on 64. Adjusts  Chorus Rate in the
Chorus Delay algorithm.

12 Decay Time Adjusts mid reverb time. Infinite reverb is available in Delay/

Reverb algorithm only. Adjusts Slope in the Gate algorithm.

13 Treble Decay Provides an adjustment of the low pass filter within the reverb.

Maximum setting gives a flat response through the filter section.

14 Bass Multiply Provides control over bass reverb time.

15 Size Adjusts the room size. The range is for one side of a room; cube  these

values to get the approximate room volume.

16 Diffusion Softens attack of percussive sounds in the reverberator.

17 High Cut Filter Provides adjustment of high frequency roll-off. Maximum

setting gives flat response through the filter section.

18 Low Cut Filter Provides adjustment of low frequency roll-off. Minimum

setting gives flat response through the filter section.

19 Reverb Balance Adjusts the mix of reverb with delay effects.

20 Wet Pan Provides a pan control for the wet output.
