You use "tick" and "tock" alternating. My suggestion is to introduce another parameter "bar". It should be able to take values 2-13. Have the "tick" only on beat 1 for every bar, e.g.:

Bar=2 tick tock tick tock ....
Bar=3 tick tock tock tick tock tock ...
Bar=4 tick tock tock tock tick tock tock tock ....

etc..

The rationale is that any "bar" has some "inner structure". For instance a 4/4 bar is not just a sequence of 4 equal beats but in fact the first and third beats are stronger than 2 and 4 and 1 is even stronger than 3. For this reason "3/4" and "6/8" may look like the same fracture but in fact the beats are sounding quite differently (when higher numbers denote more stress on a beat 3/4 is "2 1 1 2 1 1 ..." whereas 6/8 is usually "3 1 1 2 1 1 3 1 1 2 1 1 ...". It makes sense to help the user of the metronome recognize the 1-beat (usually the stroke with the most significance) in every bar by making it sound differently.

Why 2-13: the longest metrum of any significance in practical music is 13/8, used for instance in "Blue Rondo � la Turk" by the Dave Brubeck Quartet (it is sometimes denoted as 9/8 // 4/4 alternating metrum, but i think it is a genuine 13-stroke bar structure). 12/8 is commonly used for slow Blues with the "triplet shuffle" feeling,

I hope this helps.

NAME

       XmScaleSetTicks -- A Scale function that controls tick marks

SYNOPSIS

       #include <Xm/Scale.h>
       void XmScaleSetTicks(
       Widget scale,
       int big_every,
       Cardinal num_medium,
       Cardinal num_small,
       Dimension size_big,
       Dimension size_medium,
       Dimension size_small);

DESCRIPTION

       XmScaleSetTicks	controls the number, location, and size of the tick marks on a Scale. Each tick mark is a SeparatorGadget oriented perpen-
       dicular to the Scale's orientation. For example, if the Scale is oriented horizontally, the tick marks will be oriented vertically.

       If you specify tick marks for a Scale and then change the Scale's orientation, you will have to do the following:

	  o  Remove all the tick marks. To remove tick marks from a Scale, you must destroy  (with  XtDestroyChildren)	the  SeparatorGadget  tick
	     marks.  The first two children of a Scale are its title and scroll bar, and all additional children are tick marks.

	  o  Recreate the tick marks by calling XmScaleSetTicks.

       scale	 Specifies the Scale widget ID that is getting the tick marks.

       big_every Specifies the number of scale values between big ticks.

       num_medium
		 Specifies the number of medium ticks between big values.

       num_small Specifies the number of small ticks between medium values.

       size_big  Specifies the size (either width or height) of the big ticks.

       size_medium
		 Specifies the size (either width or height) of the medium ticks.

       size_small
		 Specifies the size (either width or height) of the small ticks.
