in arGRID im am using several local tempos to achieve different tempo per track
- there is a patch which contains a master tempo sync
then there are few local tempo sync modules, for them is tempo set as division/multiplication of the master tempo (master tempo controls start of the cycle of local tempos, so they start ath the same position as master tempo)
on each local tempo there is a small computation of current position o 1/16 note. those positions are then packed into array, as well the 16 led of each local tempo sync. those 2 arrays are then sent to data bus in the rack, each track of the arGRID the reads the values from this array depending on which tepmo on the track is selected.
The problem is i am experiencing tempo drift on those divided/multiplied tempos. For example i have there a track running in 1/2 tempo, after few bars it gets out of sync from other tracks
- all tracks on the same tempo divider are in perfect sync. but those divided tempos are drifting in time from the main tempo. Is it bugr or some other problem?
drift in local sync
it seems that is has to do with the usine block size.
i had 256, when i changed it to 32 the problem was eliminated

Hello Drakh
I had the same problem, different tempi using local sync.
It was working very well on Usine 5, but not anymore on Hollyhock.
After speaking with Olivier Sens, he proposed me a solution with "total ppq pos".
Master sync - ppqpos - multiply (for equivalent tempo) - trunc - has change
And you have a clic at different tempi but without variation
It is less simplier for patching, but it works very well.
Hope it helps

oh, thanks, i'l take a look at this slution
Yeah I was running into issues at once as well was told for increased accuracy use the ppq.
I assume by using Master to a Local you are running into some processing latency from that.

hah. a changed local tempos with clock. and the silly thing is that,
when i set clock sync as interval (which is computed from the tempo) there is drift as well. but whet i set the clock into note mode (so i choose the length from the combo box) and i choose equivalent note the drift disappears. funny.
