Probably no single source guide other than what you gather by reading through the forum and over time. Some, but not all posters follow these acronyms.
OP = original post or more commonly here on this forum, one-press
OPB = one-press bass (v2 appended to my BeatBuddy song names)
DOP = drums one-press (v1 appended to my BeatBuddy song names)
OPBk = one-press bass and keys; derivatives may include s for strings, h for horns, etc (if the song uses or was transcribed with 4 instruments, v4 is appended to a BB song name)
OPk = one-press and keys; may include strings or horns; intent is to give bass players their own version (v3m or v4m appended to a BB song name; the “m” indicates it’s minus bass)
NP = non-percussion
.pbf = a folder of BeatBuddy songs; in the BeatBuddy Manager (BBM) and the pedal, it’s also the folder for the different genres that come with the BBM and pedal. Users can export a folder from the BBM containing up to 99 songs. This is how Singular Sounds packages songs available from their Premium Library. Use the BBM File > Import > Folder to install the .pbf file.
PM or DM = private or direct message
DAW = digital audio workstation
To keep track when I’m working up songs and adding them to the BeatBuddy Manager (BBM), I use version numbering to identify the type of songs.
v1 stands for DOP
v2 = OPB
v3 = OPBk (or other instruments)
v4 = OPBk plus other instruments such as strings or horns
v3m or v4m = OPk and other instruments but the bass is omitted for users that are bass players
