Rhythm Tree Whole Measure Irrationals

Author 3 Subscribed Users |

I’m constructing rhythm trees that span a single tuplet per measure (see patch attached). While I was able to construct a single tuplet (5 over 4 quintuplet ratio) in 1/1 time signature (which can also be read as 4/4), I’m having some trouble producing similar tuplets in 3/4 time signature where I wish to construct 5 over 3 and 5 over 4 ratio quintuplets.

I welcome your suggestions! Thank you!

I found this in a drawer…

…otherwise the integer ratio for a 5 over 3 tuplet with a 3/4 time sig is 3/20

The problem you have is that first of all the ratios are not correct when reducing the rhythm to a 3/4. (cf patch)
The other problem is mktree. mktree will always transcribe the rhythm according to the denominator of the time signature.
If you have for instance a 3/4 timesig, you will automatically have your rhythm transcribed by quarter note and you will not have a whole irrational in your measure as i assume you want.
The best way is to use directly rhythm tree notation (cf. patch) meaning putting your proportions in your tree.

By the way it is not necessary to replicate the notes (6000) for each rhythm. the Voice object will do this by default.

Hope this helps.
