I am new to Cakewalk, so please apologize my ignorance! I spent almost two hours searching for an answer to my problem but was not successful.
Here comes the problem: I have not identified where to adjust the volume of my MIDI keyboard (V61) while playing along with replaying a track within the piano roll. I installed the MIDI keyboard without problems and while playing a track I can play along with my keyboard. However, the keyboard is pretty weak compared to the track and I could not find the knob that would allow for turning up the keyboard volume (while not increasing the master volume or the volume of the track at the same time).
Dear Hatstand, thank you for your swift response! I was able to fix my problem based on your advice. You were right: The Midi keyboard was linked to one of my tracks. I created a third track and linked the keyboard to this one. Now I can adjust the volume for the keyboard separately. Thanks a lot!
