I'm using
Win7 64 Ultimate, Cubase 7.01 build 2078
pizjuce_x64_20120111 plugin pack

I can open the Plugins as [F11] instruments, they receive my Midi IN signal, but nothing comes out of them : can't get any Piz Midi plugin to produce Midi Out Signal (to send it to another VSTi)

Can you help ?

And do you know where I can find the source files for these plugins ? I found the 32 bit here http://code.google.com/p/pizmidi/ but no Juce 64bit ones..
