Thanks for your kind words! Glad you enjoyed this. Yes! That's certainly possible. You can trigger chords from the pads in Scale Chord Mode, while playing a complimentary melody, in scale, using the keys 👍
Sorry to hear that. It sounds like FLkey might not be correctly configured. Please navigate to the MIDI Settings window within FL Studio and ensure that FLkey is set up as explained here - support.novationmusic.com/hc/en-gb/articles/4906175480722-FLkey-Manual-FL-Studio-setup?23
Afraid we don't fully understand. How are you hoping to use FLkey? If you would like the pads to function like laptop keyboard keys, you can create a Custom Mode, assigning keys of your choice to the pads using the 'Keystroke' widget - components.novationmusic.com/flkey/custom-modes/new
That's right, the Scale and Chord features shown here are built into our FLkey controllers. Afraid we're not aware of a way of achieving something similar using a QWERTY keyboard but the Image-Line Team might be able to assist you with that.
