hey all !

   These past months I'm using RT1.9 so all my questions regard this
version.

   I've been trying to figure out how to work with the different
'slider' opcodes,
   mainly slider8 & islider8.
   I've been laying some of my questions on you all lately and I would
like to try and
   summerize my questions about this subject :

   1. In what extent are these opcodes more efficient than using
seperate midicX or ctrlX
       opcodes ? (maybe even an example ?)

   2. When using these opcodes is it obligatory,  for instance,
        to use all 8 controllers with 'slider8' ?
        It looked like it is. Must I always define the entire array ?
        That's not  that of a problem, but is it a MUST ?

    3. When I use 'slider8' I have to put an initial value, but then
each
        instrument activation "springs" the fader's value to that value
and that of course
       is not waht I want when controlling ,let's say, a synth's
parameters in real-time
       via my MIDI controller. (The amp keeps dropping to zero).

      Csound gave an error message (something like ' illegal init
value') when I put zero as init value,
      trying to maybe skipp initialization.But it worked when I put the
minimum value as init value -
      which I understand should be done when using a function-table.In
my case the ifn is 0.

      Is there a way that the initializing could be skipped ?
     Am I making any sense  :-}

 I'm not asking this for my intelectual pass-time, I'm trying to convert
a big chunck of code
 to use these opcodes so I'm really looking forward for reply.

 Happy Csounding (must have heard that before somewhere)
