Time Signature Toggle

[Revisto]

Is your feature request related to a problem? Please describe.
The drum machine currently only supports one time signature.

Describe the solution you'd like
Add an option to toggle between common time signatures (e.g., 3/4 and 4/4).

Describe alternatives you've considered
Providing a custom input for time signature could be more flexible.

With this maybe there ought to be a help page (perhaps with Mallard in Yelp) that explains basic concepts and something about 3/4 and 4/4.

I would love to be able to make something in some weird time signatures, maybe a spot to put in a custom time signature would be nice

e.g., 3/4 and 4/4

I do not know what quarters mean in this context and how the denominator would affect the drum sequence. Also, I would like to set how beats are subdivided to choose between precision and compactness and to allow programming multiplets (triplets, pentuplets &c.).

I suggest this:

Relevant concepts:

• subdivision – an elementary time interval. Drum triggers are timed in subdivisions. Every subdivision is represented by a single column of boxes in the sequencer. They are specified by a number of subdivisions per beat.
• beat – a time interval set by BPM. The sequencer has visual separators between beats.
• loop – a time after which the drum sequence repeats. It is specified as a number of beats per loop.

BPM, subdivisions per beat and beats per loop are numbers settable by the user for a specific drum sequence.

The following is the screenshot in README.md with labeled subdivisions and beats. It has 4 subdivisions per beat and 4 beats per loop.

Another example with 6 subdivisions per beat and 5 beats per loop:

For simplicity, I show only one line of the sequencer.
