I watched and re-watched the video ("How to Use Drum Maps in Cakewalk by Bandlab" - suggested by reginaldStjohn: Thank you!). I was able to save a drum map (EZStandard Kit) from James Argo's zip file (thanks, DeeringAmps, for pointing that out), get the drum map appear to appear in the piano roll of the midi track (just as Mike indicates in the vid). However, exactly what to do with each of the input and output selections isn't clear in the video, and I'm assuming I have something wrong because, although I have the map in place on midi track, unlike in the video, I am unable to get sound from this track. It seems the sound plays from the instrument track, but not the midi track.
More detail which hopefully explains what I mean:
So, around the 7:50 mark of the video he describes how to change the Out Port. However, he doesn't really go into the decision-making process on this. In my case, my Out Port choices are:
1-my recording interface
(I have no idea why I have 4 EZD choices and not 1 or 5 or three dozen...). The default, when I add the EZDrummer Standard Kit as a preset (in the preferences section, as shown in the vid around 7:50) is 2-EZdrummer 1. So I went with that.
Around the 9:30 mark of the video he shows how to assign the drum map to the midi track. To do this, he changes the output dropdown for the midi track to the drum map he added earlier. So in my case I selected DM1-EZStandard Kit from the output dropdown of the midi track. What I don't know is what I should select for the midi track input, or for the instrument track input & output. These are my options for those:
INSTRUMENT TRACK Input - None, All External Inputs, All Inputs, EZDrummer 1, EZDrummer 2, and Virtual Control. Each of these has the exact same sub-selection including Midi Omni, Midi Ch. 1 thru Midi Ch. 16. Output - my recording interface, Master, Metronome, Preview, other busses I've created, Selected Track Outputs, and four "New" selections (stereo bus, surround bus, aux track, patch point...)
MIDI TRACK Input - exact same choices as the Input of the Instrument Track... Output - the choices I listed above in green. , plus the drum map I added DM1-EZStandard Kit, New Drum Map, and Drum Map Manager. In this case, it's pretty clear according to the vid that I'm supposed to select the DM1-EZStandard Kit.
When I go to the piano roll for the midi track, I see the drum map. If I click on a kit instrument on the map, I hear nothing, but I do see that it registers on the midi track's level meter. If I go to the piano roll for the instrument track, I do not see the drum map (I see the default vertical piano, as I usually do). If I tap on a piano keys, I hear drum sounds (that also register on the instrument track's level meter).
I've tried various combinations of these I/O fields plus the dropdown for the Out Port when I add the map... However, the possible number of combinations is near-endless, so that approach is kind of "needle-in-a-haystack." In addition, I've tried to find something on Youtube that specifically explains the two tracks (midi & instruments) and how to select the correct ins & outs. No luck yet.
I should add that in all of my previous recording (from way back with Cakewalk 4 & 6, and now with BandLab), I place my EZD drum patterns on the instrument track, not the midi track. Why? Simply because that's the way I get drum sounds from EZD / so that's the way I've always done it. So the behavior I'm seeing is not really unexpected, but it is a problem because that doesn't appear to jibe with being able to use a drum map.
