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 à 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
arecordmidi - record Standard MIDI Files SYNOPSIS
arecordmidi -p client:port[,...] [options] midifile DESCRIPTION
arecordmidi is a command-line utility that records a Standard MIDI File from one or more ALSA sequencer ports. To stop recording, press Ctrl+C. OPTIONS
-h,--help Prints a list of options. -V,--version Prints the current version. -l,--list Prints a list of possible input ports. -p,--port=client:port,... Sets the sequencer port(s) from which events are recorded. A client can be specified by its number, its name, or a prefix of its name. A port is specified by its number; for port 0 of a client, the ":0" part of the port specification can be omitted. -b,--bpm=beats Sets the musical tempo of the MIDI file, in beats per minute. The default value is 120 BPM. -f,--fps=frames Sets the SMPTE resolution, in frames per second. Possible values are 24, 25, 29.97 (for 30 drop-frame), and 30. -t,--ticks=ticks Sets the resolution of timestamps (ticks) in the MIDI file, in ticks per beat (when using musical tempo) or ticks per frame (when using SMPTE timing). The default value is 384 ticks/beat or 40 ticks/frame, respectively. -s,--split-channels Specifies that the data for each MIDI channel should be written to a separate track in the MIDI file. This will result in a "format 1" file. Otherwise, when there is only one track, arecordmidi will generate a "format 0" file. -m,--metronome=client:port Plays a metronome signal on the specified sequencer port. Metronome sounds are played on channel 10, MIDI notes 33 & 34 (GM2/GS/XG metronome standard notes), with velocity 100 and duration 1. -i,--timesig=numerator:denominator Sets the time signature for the MIDI file and metronome. The time signature is specified as usual with two numbers, representing the numerator and denominator of the time signature as it would be notated. The denominator must be a power of two. Both numbers should be separated by a colon. The time signature is 4:4 by default. AUTHOR
