    Thanks, Paul. We'll give the 4.0 beta a try. If it doesn't do what we need it to do, we'll live with one harp.

    Cheers!

    I've been working hard on a project with my nephew. It's a MIDI instrument that you play with range sensors and and it lights up. We got one completed and it's production ready. We've been...

    I'll give this a try! The delays aren't necessary, just for effect. I'm not sure if I'll keep them. I'll double-check the parameter values. I thought the maximum 4095 had something to do with the LED...

    BTW, I use Cantabile for routing controllers and VST plugins. It has a bit of a learning curve, but really powerful.
