i installed the VVVV.Audio Pack to fool around with some VST noding.
All the example nodes in girlpower work fine except for the VSTSynth.v4p.
When loading up there is an System.ArgumentException concerning the loading of the VST (Altair-4.dll)
at Jacobi.Vst.Interop.Host.VstUnmanagedPluginContext.Create(String pluginPath, IVstHostCommandStub hostCmdStub)
and so on and so on.
The VSTHost Node, the MidiShort Node and its (nil) input are red.
I also installed the “Visual C++ Redistributable for Visual Studio” as recommended on the vvv.Audio Pack page.
have you started the pack with the 32bit vvvv version? VST plugins need to have the same bit architecture as the host application. unfortunately most VSTs only have 32bit versions, but the 32bit vvvv version is perfectly fine as long as you don’t need gigabytes of textures in the RAM.
sure, get the arduino data and on whatever event from arduino you want to trigger a midi message send some numbers into the midi message/data pins of the VSTHost. look inside the midi out modules shipped with vvvv to get an idea which numbers to send.
