Normally, an audio signal, when MIDI-controlled by ctrl7, will output 
nothing until the controller is moved. This seems to suggest that the 
default ctrl7 initialization is 0; the controller is read only when it is 
moved.

However, with this basic instrument:
a1 diskin
kamp ctrl7
out a1 * kamp

the *full output* of diskin is heard until ctrl7 is moved (even with the 
controller set to zero). To initialize to *silence*:
ctrlinit (controller value =) 0

must be added before the ctrl7 line.

Is this a bug? Why should diskin's output be treated (by a MIDI controller) 
any different from any other audio generator? (I have very rarely found it 
necessary to use ctrlinit; the only time I can recall was when the initial 
value needed to be something *other* than zero.)
