Is this the correct syntax
aOut = asig1 * kEnv1 + asig2 * kEnv2 + asig3 * kEnv3 + asig4 * kEnv4
outs aOut, aOutOutputing signal
Syntactically it is fine, but without the entire instrument it’s impossible to say. If you have defined all these variables, then yes, If not you will get a host of errors.
