Each quarter note is comprised of 24 clock messages. It can be divided:
| note | divisor |
|---|---|
| 4th | 24 |
| 4th-triplet | 16 |
| 8th | 12 |
| 8th-triplet | 8 |
| 16th | 6 |
| 32nd | 3 |
Combining parts of different divisions require different step counts if you intend to match duration. The sum of clock messages needs to be the same for each part.
{steps} * {divisor} = {clock messages}
{clock messages} / {divisor} = {steps}
