Try this instead:

instr 1
kMain chnget “deep”

kFdBack = kMain
kFco = kMain * 10000
kGain = kMain

aInL inch 1
aInR inch 2
aOutL, aOutR reverbsc aInL, aInR, kFdBack, kFco
outs aOutL*kGain, aOutR*kGain

endin

I’ve the same thing as @hdale94 and it works fine for me:

instr 1
    kFdBack chnget "deep"
    kFco chnget "deep"
    kGain = chnget:k("deep") * 10000
    aInL inch 1
    aInR inch 2
    aOutL, aOutR reverbsc aInL, aInR, kFdBack, kFco
    outs aOutL*kGain, aOutR*kGain
endin
