Studio 1 (v5), AKAI MPK49 (midi keyboard), VI's include Superior Drummer, EZ bass, Hammond B3.
Issue: Everything has been working flawlessly for months. All of my VI instruments function properly and create sounds when the VI keys/buttons are pushed with my mouse. However, when I use the MIDI keys, even though S1 shows the "key-movement" on the instrument that is created by my MIDI keyboard, there is no sound.
I have NO idea what I did. I've checked the connections: all are good. The External Device tabs shows proper send-to and receive-from connections. Everything seems to be function properly....I just have no sound when using the midi keys.
