ANALOGUE SYSTEMS RS340 Manual

INTRODUCTION

There are occasions on which you may want to generate a Gate or Trigger at some
specified time after a sonic event occurs.
This, for example, allows you to use two VCO/VCF/VCA signal paths - one slightly
delayed with respect to the other - to create a single, composite sound each time
that you press a key. You could use one VCO/VCF/VCA path to place a "chiff" at
the start of a flute or woodwind note, and the second to generate a sustained
sound that imitates the body of the real instrument. Alternatively, you can use
this technique to create interesting rhythmic structures in which one percussive
sound is followed closely by another.
The problems encountered with triggering multiple sounds in this way are twofold.
Firstly, you will often wish to initiate the second envelope very soon after the first
- more quickly than is possible using your hands. Secondly (and even if the delay
between the two Gates is long enough for you to initiate both manually) there's
the problem of consistency: the relationship between the two parts of the sound
must be the same for each note you play.
To solve these problems there's a dedicated module that will create the appropriate
delayed Gates and Triggers for you. It's a Gate Delay.

IN USE

The RS340 is a multi-mode Gate Delay module and Shaper that recognises any
positive-going pulse exceeding +1V, and then generates a Trigger and a Gate of
specified duration a user-defined time afterwards. Two LEDs offer visual feedback
regarding the Gate status of the module.

GATE IN

This accepts a positive-going pulse in the range +1V to +20V to initiate the Gate Delay cycle.

DELAY TIME

This determines the length of time between receipt of the input pulse, and the output Gate and Trigger.
The minimum delay is 10mS. The maximum is 10S.

GATE TIME

The GATE TIME allows you to determine the duration of the generated Gate pulse. The minimum duration
is 10mS. The maximum is 10S.
