Delay~ in RNBO drifting over time

Jeff Quinn's icon

maybe some one else has started a topic but if i set up a simple delay using

delay~ @maxsize samplerate and a feedback~

then record the output, the repeats are drifting and not lined up to the beat over time.

logic/reaper is set to 120bpm/48k when recording while testing.

MAX plays a short sample into RNBO and i am using the reference patch for delay~ to test.

it looks like all RNBO audio inlets are set to signal and not auto.

audio status is: core audio, 48k, i/o 64, signal 64.

i am on a m4pro mac mini.

if anyone else can confirm this or disprove this i would be grateful, thank you!

i have narrowed it down to the buffer size in Max and in a DAW

if i have low buffer settings like 32 or 64 the drift is minimal. when set to 1024 or 2048 it is significant.

i have tried inserting sig~ before the delay~ and it did not help.

i have also removed the ramp and interpolation in the delay~.
but unfortunately none of those work to fix the drift increasing with buffer settings.

any thoughts?
