'beats' are integers?

Hi,

I've come across a problem when using my plug-in with Ableton Live, and I wonder whose problem it is.

At the root of it is an AU parameter of type kAudioUnitParameterUnit_Beats.

I expose this to users as a float, min 0.0, max 128.0. When controlling it via MIDI, I set the value to (1+x) where x is the MIDI CC value, giving a usable range of 1-128 (integers) via MIDI.

Live exposes the parameter as a value from 0-128 (fair enough) and displays only integer values to the user. However, the value it is applying to my plug-in doesn't take integer values - I imagine it's incrementing in steps of 129/128, as it maps the range 0-128 to a 7 bit controller value.

So, who's right here? Am I wrong for allowing a 'beats' parameter to take fractional values? Or is Live wrong for showing a fractional value rounded to the nearest integer?


cheers,
os.
