Deiter,

thank you for your prompt response. I did as you suggested, and my Dark Energy 2 behaves correctly when driven by my Dark Energy 1's ADSR envelope output into its VCA input.

I then unplugged the connection into the Dark Energy VCA input, attempted to drive my Dark Energy 2 from its own ADSR generator, This no longer works.

This confirms your theory that the my Dark Energy 2 has a fault. I will return it to the UK Distributer (EMIS) for repair.

Thanks again,

Blair
