Delay

Delay is an effect on the RC-505 and RC-505mkII. It adds a delayed sound to the direct sound, giving the sound greater depth or creating special effects.

Parameters

Name	Value	Description	Notes
Time	1ms–1000ms, 𝅘𝅥𝅰–𝅗𝅥	Specifies the delay time.
Feedback	0–100	Specifies the number of delay repeats.
E.Level	0–100	Adjusts the volume level of the delay.	Can be controlled by the Input Fx/Track Fx knobs.

Time

The Time parameter defines the interval between each repeat. Some intervals are small enough to produce a musical note. Most of them are not perfect tones (when compared to the standard 440Hz scale); nonetheless, they can still be heard as notes. Below is a table with Time values and their closest musical note.

Because the Time values have a specified unit (unlike Granular Delay, for instance), the frequency (Hz) of the note played can be calculated by using the following formula:

$F(t)=\frac{1000}{t}$

• After a Time of 32ms, the interval is too large and no specific notes can be heard properly.
