drawback in using [vline~] as the 'table index driver' - compared to
[phasor~]: it doesn't allow to change speed at samplerate (yeah, it is
possible, but only by sending sr * times messages per second -> very
expensive, i suppose).
phasor~ doesn't allow speed change at samplerate either. it allows speed change at block rate.
so if you want to work with a metro and vline's triggered every 1ms, it would still have better resolution than a normal phasor for speed changes.
