Victoria:

Just to be clear on what you're trying to achieve, can you please take a few minutes and try this (I'm assuming you're using BIAB 2014)-

- open a new, blank BIAB song
- go to Opt. > Preferences > Count-in/Met. and UNcheck "Audible Lead-in"
- also set "Visible Metronome" to "No visible metronome", then OK, and OK
- on the very top menu bar, click Styles and ensure "Style is enabled" is checked
- on that same dropdown, select "Browse Styles with info"
- select this style _CELTJIG and OK
- in the chordsheet grid window, type C.d into bar 1 and the same into bar 2
- in bar 3 type just C

Now play the "song" and see if that's what you're after for a Bodhran count-in. If not, report back and we'll try something else.

Good luck!
