hello,

i am starting with blue & csound and would like a little help.
i have made a blue.SoundObject.Sound in the timeline
and would like to control one of its paramaters with a LineObject

 in my generic editor i have this:

;insert instrument text here
kgsize = .05


a1      granule 7000, 12, 1,  1, 0, 2, 4, 0, 0, 4, 0.1, 30, kgsize, 30, 
20, 20, 0.69, 1, 1.42, 0.29, 4, 0
a2      granule 7000, 12, 1,  1, 0, 2, 4, 0, 0, 4, 0.1, 30, kgsize, 30, 
20, 20, 0.39, 1, 1.42, 0.29, 4, 0

        outs    a1,a2

and in my table i have:

f2 0 2097152 1 "/home/rob/mechanism.wav" 0 4 0


ok so all that works fine...


i would like to have something like:

kgsize = grainsize


then a LineObject called grainsize to control it.

is this possible to work this way or do i need to make a BSB instrument 
in order to automate parameters?

if the later what would such a BSB look like? i have had a go at making 
one and looked at some examples in the blue share but don't seem to "get it"

many thanks

p.s. whats the csound community like here in london uk? i never meet any 
csounders here... all pd and supercollider heads - i need to find some 
people i can barter pints for knowledge with...

Hi Steven,

Many thanks for your reply - this has got me started nicely.
I have now made a granule BSB instrument which works perfectly from the 
GUI controls.
one problem i still have is this:

1. the krate inputs work fine from the automation timeline kgize or kgap 
for example - but i am having problems with the i signals such as 
ivoice, ipitch or iatt. here is the error i get:

error:  input arg 'gk_blue_auto2' of type k not allowed when expecting 
i, line 95:
ipitch1 = gk_blue_auto2

i am guessing:
gk_blue_auto2
should be
gi_blue_auto2

or something... but cant find how to change the code for this.

Many thanks

rob c
