My kits are available for download in the Resources section of the Forum. I do not have another publicly available location for download.
The attached document should give you some insight on how to edit or create a kit. To create a kit from scratch, within BB Manager, Select Drumsets>New Drumset, although, it is many times much easier to edit an existing kit. LBDM 4BB in the attached document refers to a commercial package I made to replicated the Alesis SR-16 on the BB. If you’re interested, it’s $39.99 for Forum members. You can find out more here:
To make your own drumkits, you would need to create or obtain wav samples of the instruments you are placing in the kit. For BB, wav samples should be 44.1 khz, 16 or 24 bit samples, with no meta data attached to them. I have a couple packages of samples on the Forum in the Drumkits section until the search “Roll Your Own.” Roll You Own kits

Volume issues are discussed in the document. As long as the sample is not clipping, you can adjust the volume lower within the kit if it is too loud.
