I'm attempting to use vstinit, as a first step in instantiating a VST plugin.
QuteCsound (running Csound 5.13 in Windows 7 64-bit) doesn't seem to want to
let me use it. No matter what I try, I get a "no legal opcode" message.

I'm specifying the absolute path to the .dll. I've tried using
forward-slashes, as suggested by the manual page, and I've also tried double
back-slashes, as shown in the example. Neither option works. I also tried
single back-slashes.

This line, for instance:

gipianoteq      vstinit         "C:/Program Files (x86)/VstPlugins/Pianoteq
3.5/Pianoteq35.dll", 1

My copy of Pianoteq is in the path shown above ... my VstPlugins folder is
not in the Steinberg folder, for reasons that are both obscure and slightly
embarrassing. But my other apps have no trouble finding the plugins.

Can anyone suggest another syntax to try? Thanks in advance for any tips!

The "no legal opcode" mesage suggests that the dll containing the
opcode is not found.
Do you have the file "vst4cs.dll" in your plugins directory ? (e.g.
C:/Program Files/Csound/plugins64).
If I remember correctly there are some restrictions on the
distribution of this file, related to the Steinberg VST SDK, this
might be the reason why you dont' have it.
I should be included in Michael Gogins' Csound installer available at
http://michael-gogins.com/?page_id=59

If you have the file, you can take a look at the console print to see
if Csound complains about not being able to load it (don't remember
the exact locations in the console print, but it should be somewhat
early after starting Csound.)

Thanks, Oeyvind. That seems to solve the problem, at least to the extent of
letting me start experimenting.

Oddly enough, Michael's version of 5.13.1 crashes QuteCsound when I try to
run my .csd containing vstinit. However, when I switch back to 5.13.0 (after
copying vst4cs.dll into its plugins64 directory), QuteCsound is happy to run
it. I'll try to track this problem a little further if I have time tonight.
