[3.1.0] Tempo callback not called if new tempo matches old tempo

[tehpsy]

After setting up link: _linkRef = ABLLinkNew (120);

Then changing the tempo: ABLLinkSetTempo (..., 120, ...);

The tempo callback (defined ABLLinkSetSessionTempoCallback) is not called.

When the tempo is set to anything other than 120, the callback is called correctly. Not that this was not the case in Link 2.x -- the tempo change callback would always be called.

Is this intentional behaviour? It is surprising!

Yes, this is intended behavior.

So when i.e. creating the object that should listen to the tempo, one would:

• Create the object
• Register the callback
• Use the ABLLinkGetSessionTempo() to set the initial tempo of the object

After that the object is updated from the callback every time the tempo (actually) changes.
