MIDI Click & Countoff Rack
If you run tracks and want a professional grade click and countoff rack, then this is it, (if you can stand my voice that is)...
There are six numbers, plus an 'and' sample for subdivisions. There are options with a click (better imo) or without (for a gentler countoff).
There are four click sounds, a hi and low Ableton click sound plus a hi and low clave sound. Of course these are easy to swap out if you have something else you prefer.
There are two customizable macros:
Velocity Sensitivity: this adjust the velocity response so you can use MIDI velocity to emphasize or de-emphasize individual click/countoff samples. Simply dial this knob back to 0% if you want everything to be at equal volume.
Countoff Volume: This raises or lowers the volume of all the countoff samples without affecting the click. Useful for global tweaks so you're not manually adjusting MIDI velocities, or so you can automate countoff volumes on a per-song basis depending on the intensity required.
