Started playing around with some OPB songs and different drumkits with bass. All that I did played fine in BBM, but when transfered to the SD card and loaded into the BB, some drumkits which were supposed to have bass didn’t play the bass part through an amp from the ‘L/Mono’ output jack on the BB. The drumkit that didn’t play is ‘NP Standard Pro with Bass’. The drumkit that worked OK is ‘SuperBassG’
Looked at all the MIDI note assignments in the drumkits, etc and all that seemed OK. Finally plugged headphones into the BB. The non-playing bass was in the right side can on the headphones. Then swapped the amp cable to the ‘R’ jack on the BB. The bass came through the amp along with the drums.
Most all my other gear that has an output jack marked ‘L/Mono’, outputs a mix of left summed with the right by means of a contact that is closed in the right jack that connects over to the left jack when no plug is in the right jack. The BB isn’t not working this way and oddly testing a bit further it seems the right output jack is the mix of left and right if I plug a source into the ‘L/Mono’ or ‘R’ Input jack. I think the stereo drumkits are also mixed to the ‘R’ output jack also. If I plugged a source into both left and right inputs the output is then on the respective left and right output jacks, but not mixed on the right as when only one jack of the inputs is used.
Is the labeling on the output jacks reversed as to the intended electrical design of the BB or an error in the electrical design that didn’t match the labeling?
In the PDF manuals I have I don’t think I found mention of the input or output jacks and how they they may configure/route themselves depending on what is plugged in. Are the output jacks dependent on what is plugged into the input jacks as well? It seems so as the outputs split out to stereo when two jacks were plugged into the inputs, rather that mix it to a single mono output.
If anyone else would try different input and output combinations your results would be welcomed.
