This is exactly how I've always understood the convention to work.

Signal sources (oscillators, noise generators, microphone) are often
represented with a circle. Modifiers (VCF, VCA, inverter) are often
represented with a triangle (like an op amp). Controllers (ADSR,
keyboard, sequencer, bias source) are often represented with a
rectangle. But eventually even this breaks down because LFOs can be
considered controllers at low frequency or signal sources at audible
frequency.
I think one needs to use the appropriate symbol for the
module on a per-patch basis. Ask yourself, "Self, is this generating
an audio signal, generating a control signal, or modifying a signal?"
Other conventions are that audio signals enter at the left and exit
at the right of a module. Control signals exit at the left and enter
at the bottom of a module (but I've got many examples showing control
signals exiting anywhere). I'll post some scans within the next few
days.
