Hi Nicolas,
I'm not sure but I think it's the total amount of dsp ticks since the opening of PD and it's mostly used by the block objects to know when to run their DSP blocks (something like if dsp_phase%block_size==0 then perform).

Hello,

I really have hard time to understand what's the dsp_phase variable (d_ugen.c) is supposed to do.
I obtain always zero or weird values in the prolog / epilog calls.
Is it related to the one shot tick feature provided by the block object?
Thanks for clues or links to any information/discussion.
