can be fed to the AUX input of the other. More varied arrangements can
be made using an external mixing console. These configurations can be com-
plex and will require experimentation to find optimum settings.
3.9 RESEARCH TOOL
M.93 can be used as an effective research tool in fields such as linguistics
and psychoacoustics. The REPEAT HOLD function, for example, enables syllables,
words, or other sounds to be locked up and repeated over and over again
fo~
analysis. They can also be slowed down or speeded up and altered in pitch.
Classic delay effects can be reproduced such as the

(sec-
tion 3.6), comb filtering (section 3.4), and spatial localization (section
3.1). And undoubtedly, there is more to be learned about the effects of
delay. The VCO also can be helpful in studying the perception of repetitive
phenomena such as vibrato and

and flutter

One of the unique advantages of M.93 is the ability to achieve up to 2 seconds
of delay time. This feature is very useful for echo type effects,and enables
a live performer to produce musical textures not possible with a single in-
strument.
For example, mix a one second delay with the dry signal. Play a guitar
chord and you will hear it repeat one second later. Slowly play a scale,
and if you time it right, you can play harmonics on top of what you played
one second earlier. Now add in another delay at two seconds and the texture
becomes even fuller. Feed the longer delay back to the input and you have
a decaying echo. You can simulate the effect of an echoplex and make one
guitar sound like a whole chorus of guitars.
Try staggering the delay times to get syncopation effects, and feeding back
different amounts of different delays to create widely varying rhythms and
textures. The range of possibilities is extremely broad; experiment to find
new and exciting sounds you've never heard before.
The REPEAT HOLD feature is extremely useful for live performance. You can
lay down a two second riff, lock it up in REPEAT HOLD with the foot switch,
