[Q] export does not generate valid vst plugin

[zucker1]

HI!
I've a big Problem... (first of all sorry for my terrible english)

when exporting my Project as an vst-plugin, the generated dll does raise an error within my vst host.
The host simply says, that "The dll is not an valid vst plugin".

I did several plugins with the old synthmaker, and they all worked fine.
Any idea/hint what the Problem could be?

(The vst host is an propretary host of one of the largest professional mixing consoles, but isn't supported well. It seems that it can host only simple vst1.0 plugins)

MANY thanks for any help.

I exported your synth and it works fine in FL Studio

Hi and thx you're helping

You're right, it runs on most hosts...BUT the propretary "lala-engine" from lawo doesn't load the plugins created with flowstone. BUT it loads plugins made with synthmaker...
WHY can this be? What are the differences???

I've used vst_Scanner to see if there is any difference or problem, but bot plugins (from synthmaker and flowstone) show up as the same sdk 2.4 and all other values are the same....

I've tried to rebuild the project in the synthmaker, but there the Sample&Hold module does not work, and i can't find the reason. (the output of the crossfade signal delivers unuseable values...i opened another thread in the dsp forum about that)

So i'm stuck, and i need the plugin to work within a week, otherwise i'm getting big troubles on air
And i need to use this "fuzzy" vst host, as it's the one that works with the lawo mc99 mixing console.


PLZ, do u have any other ideas????

Hi,
i'd really Need help.

i've compiled the same OSM Project with Synthmaker AND Flowstone to vst plugin.

The vst plugin scanner does not show any differences between the two plugins, and both of the are valid within the scanner.
BUT only the Version compiled with the old Synthmaker can be loaded within the VST host.
The Flowstone Version throws an:

Code: Select all

bool EffectFab::initVSTEffect() WARNING: can't open dll
xxx.dll is not an valid VST Plugin

Could anyone give me a clue?

IT cannot bei vst 2.4 in synthmaker, 2.4 was introduced with flowstone...

[zucker1]

THX for your reply
Sorry, you are right.... 2.300 SDK with Synthmaker and 2.4 SDK with Flowstone.

Are there big differences between 2.300 and 2.4 for the host site?

[Nubeat7]

maybe the host supports just vst 2.3... anyway never heard about that host "lala engine" ?? maybe just use another host..

[zucker1]

beleave me, i would use any other host, if i only could.
tha lala engine is the host that is written for the lawo mc66/99 mixing consoles (it is fully embedded in the console and can be controlled by it). Sadly, there's nearly no Support for the pluginhost (other than for the console itself), and there's NO (!) documentation about what sdk Version is supported.
I've thaught that only the Major Version matters, but now i learned my lesson.
So it Looks like i've to use the ols Synthmaker for the time beeing...

Maybe have a closer look at Lawo? They only present something called "JADE engine". If you create an account, you can download a demo version. Maybe JADE is the replacement for lala with up-to-date VST specifications?

[zucker1]

the JADE engine is only for the Radio consoles (and does not work with the mc series).
The lala engine is bundled with the broadcast consoles.

"it works as designed!" (i can't hear this anymore)

now i non't know hot to go on.
