<div>Thanks to all of you for your quick replies!</div>
<div>I will check out all of your suggestions and @Christoph, looking forward for your worker thread implementations.</div>
<div>I have never heard of Supercollider, would that help my in any way?</div>
<div> </div>
<div>Cheers! Jakob</div>

<div name="quoted-content">another trick is to use [readsf~] in an upsampled subpatch.<br/>
<br/>
BTW, I have ideas for adding a worker thread to Pd (similar to Supercollider), which would help solving a lot of Pd's realtime-safety issues. I want to do that in the next couple of weeks when I have more time.<br/>
