Delay Time cont'd.

You can set and display delay val- ues in units of time, or with tempo values. Press Up and Tempo simul- taneously to toggle between these two options. When time units are selected, delay times are set and displayed in milliseconds (From 0ms to the maximum available delay for that parameter). When tempo val- ues are selected, delay values are set and displayed as a ratio of ech- oes to beats (from 24:1 to 1:24). This will automatically synchronize the delay to the current tempo (MIDI, Internal, or TAP — see Tempo Mode in Chapter 2.) For example, a delay setting of 1:2 (1 echo for every 2 beats) will produce half-note delay rhythms synchronized to the current tempo.

Voices

These parameters set the delay time, in seconds, for each individual voice. The range for each algorithm is shown below, along with the delay time available with optional SIMMs memory expansion for those 6-Voice algorithms which make use of additional memory.

When display of values in BPM has been selected, these are set as fractions of a beat. The smallest fraction is 1/24th beat. Changing these values live can produce a variety of pitch shift, and flange effects. Delay times can also be tempo modulated.
