If "callbacks" is ON, Pd runs directly in the audio callback. This
gives you lower latencies, but less "leeway" for CPU fluctuations
- unless you increase the hardware/jack buffer size accordingly.<br>
</p>
<p>If "callbacks" is OFF, Pd uses a polling scheduler which runs
independently from the audio callback and exchanges audio via a
(lock-free) ringbuffer. This ringbuffer essentially adds some
extra latency, so that Pd is allowed to "fall behind", as long as
it can catch up again. You can control the latency with the
"Delay" setting, independently from the actual hardware/jack
buffer size, which can be quite useful.<br>
</p>
<p>As a rule of thumb: don't use "callbacks" unless you *know* that
you need it :-)</p>

<div>That did the trick, with callbacks ON DSP works. I never
used it before, and to be honest, I don't know what this does,
but for now it solved the problem.</div>
<div>Could you (or someone) explain briefly what this is for? Is
there any impact elsewhere (maybe performance) by using it
enabled?<br>
</div>
<div><br>
</div>
<div>Anyway, thank you so much for the hint.</div>
