Setting audio delay to 0ms works. Latency is same as midiin midiout for all the midi objects now. Thanks

I am building pd patches on a raspberry pi. I've noticed that (i think) all the midi objects other than midi and midiout seem to introduce a significant latency. A simple

• midiin > midiout

has a latency within puredata of about 7ms, but

• notein > noteout

has a latency of 29ms. Is this a known issue?
