Muso:
I've tried your process but to no avail.
When I click "Record melody" I get the Record dialog, then press the Record button.
When I try to play the computer keyboard I get nothing from it.
The VU meters show activity for both input and output but it appears like the Input is coming from the Output.
There's no input from qwerty.

Bob:
I have the TTS-1 synth selected.
Yes I get sound when I play a MIDI only style or when I play a RealStyle, even with no input driver selected.
It's the "upstream" part that isn't working. That is, I can't get any input to sound.

I also tried your idea of the Big Piano Window.
Thought perhaps I could record from there. No luck. The notes sound when I click on the keys, but those notes don't get entered into the Melody track when I do a "Record".

I did search extensively the Help files, videos etc. They do a great job explaining how to PLAY ALONG with the Playalong Wizard, plus how to set up a MIDI keyboard as an input device, but nothing about how to GET an input device into the "MIDI Input Driver" box. (at least that I could find)

The popup over the red Record Midi button shows this: (below)
Thanks all for the help.
No solution yet ...

POPUP
"Record MIDI to Melody Track.
This records external MIDI information from your external keyboard. It will also record notes click on the on-screen piano, guitar, drums, as well as from your qwerty keyboard if using the Wizard Playalong."
(My "Wizard playalong feature" is ENABLED)
