C++:
VstIntPtr function dispatcher(AEffect* e, VstInt32 opcode, VstInt32 index, VstIntPtr value,
void* ptr, float opt);
Delphi:
function dispatcher(e: PAEffect; opcode, index: VstInt32; value: VstIntPtr; ptr: pointer;
opt: Single): VstIntPtr; cdecl;
always returns 0, unless otherwise defined.
all string-pointers points to zero terminated strings.
