LEFT HAND CONTROLLER
EXTERNAL CONTROL OF GLIDE AND FINAL DECAY.
The rocker switches in the left hand controller section
have replaced the momentary push buttons used previously. Jacks
have been added so that the performer can connect foot switches
to engage GLIDE and DECAY functions. R. A. Moog will soon make
these momentary switches available as an accessory.
With no external switch connected and the GLIDE switch turned
"off" there will be no portamento. When the GLIDE switch is turned
"on" the pitch will glide between notes at a rate set by control 2
(see page 8 paragraph 12). When the performer connects the external
foot switch, he can momentarily engage portamento when the GLIDE
switch is off by depressing the switch button. The foot switch has
no effect if the GLIDE switch is already on.
The external control of the DECAY function works in an analogous
f a s h i o n .
To prevent confusion of the external foot switch cords with
input and output audio and control voltage cords, the jacks for
DECAY and GLIDE are 0.206" dia. instead of 0.250" dia. The
jacks mate with Switchcraft S-260 plugs instead of ordinary 1/4"
phone plugs.
The external switch is a normally closed type. It opens when
the button is depressed.
