Re: Virtual keys play, but no sound
If I understand what you've been trying so hard to explain, it seems I would have needed one cable to send MIDI signals from the Casio to the Surface and another cable to send sound from Pianoteq on the Surface to the Henriksen.
I don't recall having any such device, nor is it referenced in any of my notes or emails. and again, I do think I plugged ONE cable into the headphone jack of the Surface. My gig packing list does reference a 1/4" cable. Perhaps I had a 1/8 adapter on the Surface end. But that still wouldn't make sense - one cable when two are needed?
Let’s try something, OK? Sometimes one step at a time helps.
Earlier in the this discussion, you wrote:
There's a TRS cable connecting the Casio to the Henriksen amp.
If I’m looking at the right manuals, the plug that fits into the Casio should also fit into the headphone jack on your Surface Pro 7. If it does, try this:
Take the plug out of the Casio and plug it into the Surface. Leave the other end in the Henriksen.
Turn on the Surface and set its volume really low (but not quite off... maybe 10% or so).
Turn the volume all the way down on the Henriksen and turn it on.
On your Surface, go to some website that makes sound, like a YouTube video. Or use a music player, if you have one installed. Anything that makes sound will do.
Now turn the volume on the Henriksen up a bit and see if you hear what’s playing on the Surface.
If the volume is too low when you have the Henriksen volume somewhere in the middle, nudge the Surface volume up carefully. You want to get the Surface volume set so that you can control the volume easily with the knob on the Henriksen.
If you get that far, then we know we can get sound from the Surface into the Henriksen, and we can move on to the next step.
