Problems with rythmical syncronizing during acceleration of speed

Hi, I’m trying to realize an additive synthesis of pulses for having a serie of multiple rythms.
For example I would like to have two different pulse trains with two different speeds: respectively 1T and 2T. These pulses generator must be in sync with phase, also when I’m going to change their speeds simultaneously.
I’ve tried with train~ object and also with metro + click~, but there’s a progressive and continuos phasing, also when Speeds are constant.
Can anyone help me to solve this?
Many thanks

look at phasor~ + rate~. figure out how to turn phasor~ into a pulse and you’re set.

even in a signal-only system with two pulsetrains you will
find that the timing resolution ends at the samplingrate.

the last inlet of train~ should take signal, too – is that
what you are looking for?

Would the train.shift~ external from Nathan Wolek be useful? It will give you pulse signals with evenly-spaced phase relationships between each output.

I think it’s in the granular toolkit package if you’re interested

Thanks!I’m trying now this workaround, I will let you know my results.

Maintaining rhythmic ratios across varying tempi is one of the key features of my external samm~ which you can find here:
