i have been working on a new sequence patch for someone and i knew about [transport]s lack of hitting in timing, or hitting things right on the money, it was always a little off, i have included a audio demo.

the hits are just happening as 1-5-9 etc, just a simple 4/4 beat, but it does go off.

the same is also happening with [phasor~] set with the @lock 1 attribute with 16n, and having different clocks available. but even when i play withe [phasor~] is sets all my sequencers completely off, not staying on the same path, after about half way through the sequence.
i have put a screen shot of it when you first start the sequence, but leave it a few more second and they all trail from each other.

i know the difference between max and msp timing, but seems to be having trouble with both at the moment. does anyone have an alternative or a patch which can solve this problem.
basically a fool proof transport which actually hits the sequences on proper times and does not mess with the timing as well.

i will be working on more alternative and searching around, but even when i found a few possible answers, they all cam e up the same

cheers

Maybe you can post the patch here (or at least the part which is relevant for timing).

here is a [phasor~] type of transport i have been messing with. i have noticed though that max timing is slightly off from msp timing. max seems to lag a little

But transport (with quantized metro) works perfectly for me.

Handling real time data on low-priority threads will inevitably lead to sloppy timing.

but thanks for your interest as well, it helps to get second opinions

im working on some new patches for a client
now i am just using the global one that is in max, but still having this strange lag for some reason, and this is when im just doing test.

any thoughts?

was wondering whether to try msp trasport again… maybe
but would be great if you could help
