Phasor, What behaviour

Hi,

I've got a few questions re how Phasor and What behave. Please see the patch attached:

1- When Phasor is turned off while in syncupdate 1 mode, Live.scope shows an incredibly high frequency. This does not happen when syncupdate is 0.

2- What does not seem to work in ascending mode? There's a workaround by using Change, but is there a reason What does not work? Basically, I'd like to get a pulse ONLY when the ramp starts but when I use prob with Subdiv, I get a pulse on ramp start and ramp finish.

3- When increasing tempo, What and Change give me ratcheting pulses. How do I avoid this?

Thanks
