The table below summarises the relationship between Factor and Delay Time:

FACTOR RATIO TO BPM

1 1/24

2 1/16

3 1/12

4 1/8

5 1/6

6 1/4

7 1/2

8 Equivalent to BPM

9 x 2

10 x 3

11 x 4

12 x 5

13 x 6

Alternatively, a delay time may be set directly by adjusting the BPM and Factor

controls while observing the Delay Time display. Factor will operate as a “coarse”

delay time control, while BPM will act as a “ne” control.

Additionally, the output of the delay line may be fed back to its input with the

Feedback control to create multiple echoes with decaying amplitude.

Tap Tempo – Softkey 1 may be used to input a BPM value by tapping the button;

a minimum of three taps is required. The tempo of the taps will then dene the

delay time.

Sends – the Send Reverb control sends the Delay module’s output to the Reverb

module.

Module output – the output level of the Delay module is adjusted with the Delay

Out control. A Delay Pan control is also provided.

Module 3 – Reverb

The Reverb Module offers six basic room/plate simulations, which may be

selected with the Preset control:

Hall Bright – a large space

Hall Warm – as Hall Bright, but with less hard surfaces

Room Bright – a small space

Room Warm – as Room Bright, but with less hard surfaces

Plate Bright – simulation of a traditional echo plate

Plate Warm – as Plate Bright, but with reduced HF reections

Once a Preset has been selected, the reverberation may be modied as required

by adjusting its various parameters.

Filtering – the Reverb module is provided with the same variable-frequency

hi-pass and lo-pass shelving lters as the Modulation and Delay modules. The
