I'm new to the forum and just started using Cakewalk, and I can't seem to resolve a problem.
I connected the "Nektar Impact GX mini" MIDI keyboard to my computer, followed the Cakewalk installation instructions, and launched the program.
I opened a Cakewalk project and the keyboard was connected correctly, as you indicated. When I play, the volume sliders move, but I can't hear anything.
The keyboard works fine in Ableton Live.
