Correct. You can find most of the kits you need by searching Resources/Drumkits on the old forum. However, Daydream Believer requires a kit with keys and horns—not the NP StdPBass 63-91 kit (which can be found at http://forum.mybeatbuddy.com/index.php?resources/np-stdpbass-63-91.2023/ )
The kit for Daydream Believer is identified in the enclosed BBM screen shot
With the later versions of the BeatBuddy Manager (BBM), there is no longer a 500 MIDI note limit to songs so if you’re using 1.6.5, you can now have songs with >500 MIDI notes.
If you’re interested in tutorials for building drum sets, BeatBuddy Worship has made one available. I think, but am not positive that he’s also worked up some wav tutorials. He just posted a Youtube link to Writing a Song from Scratch in Midi Editor - Full Drum Writing Workshop
There are tutorials on creating BB songs with a DAW available from Guitar Stu and Phil Flood. I’d search this forum using “tutorial” to see what you come up with.
Sometimes you need to use a utility such as Tag Stripper or Switch to clean up the wav files so that they work in the BBM. This is mostly the case for Mac users but since you’re using Windows 10, I’m not sure what the issue would be. Is your wav set for PCM 44100/16bit? If not, you’ll need to do so. You can try using Audacity to see if it helps (doesn’t appear to have been updated in quite a while).
