INTRODUCTION
While digital audio processors are often plagued
by latency issues, analogue circuits are known for
their instant response. But what if you want to
delay a signal on purpose, without the use of
tape or digital memory? Enter the bucket
brigade delay (BBD) line: a series of capacitor
'buckets', which pass the incoming signal along
at a high rate in order to delay it.
Delay 1 is a fully analogue BBD-based delay
module with a multitude of features geared
towards modern musical use. An integrated
temperature-compensated,
voltage controlled oscillator (VCO) provides the
'clock' signal necessary to drive the delay line
within 1 to 50 ms.
By increasing the drive frequency to over 20 kHz,
the typical 'BBD clock whine' problem is solved,
while still providing a wide range in delay time.
Classic chorus, flanger and echo effects are easily
achieved using the dry/wet blend, feedback and
damping parameters.
To greatly reduce distortion and noise, Delay 1
includes a newly developed control circuit. The
improved fidelity is maintained at a multitude of
signal levels by an integrated high-performance
compander, while preserving signal dynamics.
The module's 'split phase' topology provides two
different dry/wet mixes, which may be used to
convert
mono
signals
complementary comb filtering and more.
Delay 1 also allows you to experiment with
Karplus-Strong synthesis, an exciting technique
to create string and percussion type sounds. This
is made easy by an integrated noise transient
generator, driven by the 'pluck' input, and by the
clock VCO's 1 volt per octave response.
By re-engineering the classic analogue delay line,
Delay 1 brings the unique magic of BBDs into the
contemporary electronic musician's arsenal.
