maybe something missing in my understanding of globals. Toot 9 p105 and 106
in manual. together, instr 9 and instr 99 allow me to control balance of
dry sound but not of wet (wet sound looks equally loud in both channels).

correct?

if that really is the case, could someone please suggest best way to create
a single ibalance variable that would control balance of wet to dry -global
crossfade? (also recalling that there are mathematically different types of
crossfades).

garvbsig  init  0

instr9
idur      = p3
iamp      = p4
iskiptime = p5
iattack   = p6
irelease  = p7
ibalance  = p8
irvbgain  = p9
kamp    linen      iamp, iattack, idur, irelease
asig    soundin    "soundin.aiff", iskiptime
arampsig  =  kamp * asig
     outs    arampsig * ibalance, arampsig * (1 - ibalance)
garvbsig  =  garvbsig + arampsig * irvbgain
endin

instr99    ; global reverb
irvbtime = p4
asig   reverb  garvbsig, irvbtime
    outs  asig, asig
garvbsig  =  0
endin
