Thanks @samaaron. I had a look through the source code, and while it does quantise the input note to the nearest midi number, it doesn’t _look_ like it’s inherently limited to whole numbers, since the ugen has a `tune` input that looks like it’s for the fractional part of the note ([here](https://github.com/supercollider/sc3-plugins/blob/42a1bc6d160783b21129ddc7fbcfc63623935ba3/source/MdaUGens/MdaUGens.cpp#L87)).  
When I get a bit of time I may try compiling a synthdef with the fractional part of the note wired up to the `tune` input and see if I can get it to play non-integer notes.
