Sorry, Scott, but your comment is simply wrong.
The format of the DmWrite call is
Err DmWrite(
void *recordP, // destination
UInt32 offset, // offset within destination
const void *srcP, // source
UInt32 bytes) // number of bytes to write
(this, sans comments which I added) is from DataMgr.h.
DrumBSF's code DOES write from newRecord to newRecordPtr
(assuming that the database got opened/created ok), it
just does it twice...

There is no association between newRecord & newRecordPtr. newRecordPtr
refererences your record, but you're writing your data to newRecord
which is NOT what newRecordPtr references.
