About Personnel Variance (II): Rules for handling P.V. in J-DISC
The basic rule is simple. Main Session personnel and corresponding skill should be those that hold for every track on the session, or as close to it as possible. Any variations from this main list must be entered when creating the individual track and will show up in the session display for that track. It must be entered as specifically as possible to say exactly what is happening on that track, with no assumption that the viewer knows what has changed.
If someone is playing a different instrument for their main one on a given track, he/she is entered playing that instrument on that track. The system will recognize the name and override that performer’s instrument, displaying the new one automatically in the track column and in any import of the track to an issue.
Where that person plays two instruments on that specific track, it must say so explicitly. His/her main instrument must be re-entered in the track input window, and will be displayed along with the new instrument. This may seem redundant. But the “variance” is that that person plays two instruments instead of one, or three instead of two, etc. It’s consistent by dint of the rule that the exact roles must be stated in each track.
If someone is added for one or more tracks, their name and instrument should simply be entered for that track and that information will be displayed.
If someone drops out, you can simply say “omit” + [their name]. That is, you choose “omit” from the instrument drop down menu instead of their instrument.
Say someone does not play one instrument on a certain cut, but plays two on all of the rest. Or someone replaces him/her on that instrument. This is one area where the current setup is a little ungainly. The performer should be entered with both instruments on every track except the ones where he plays only one. This may be adjusted in future versions. For now, when working with personnel variations like this, it is easy enough to use the “clone” function in creating these multiple, very similar tracks, to lessen the burden of data entry.
If an individual plays on a few tracks and not others, the input user is free to decide how to indicate these variations. If they play on more than half the tracks, however, it makes sense that they be added to the main session personnel list (rather than track by track), then shown as omitted from specific ones they don’t play on. The reverse is true if they play on less than half.
In effect, the complete session personnel is what you see between main session personnel and personnel variance. It might be possible, however, to generate a list of “collected personnel” with the pertinent performers’ names only, that would appear somewhere in the record.
