packed audio flow does not start fractional delay anymore

Hi,
A long time ago since I've entered this forum.
My eTap2 echo application's wow/flutter mechanism (fractional delays managed by complex waveforms) does not start anymore. I've tried alot of sensible things but discovered that placing a oscilloscope somewhere, even without connecting it the fractional delays are working 100%!! I made use of the packed streams alot and though of also unpack before entering this w&f routine without luck. So the bottom line is adding an element without connecting starts it? Any pointers ??

I think it's too hard to trouble shoot with so little detail.
Is the W&F mechanism part of some larger sound processing that continues to function while it does not?
Is the problem specific to within SynthMaker or does it persist in the stand-alone or VST exports of your OSM?
Have you tried different sound drivers (on the DS Out primitive)?
I'm wondering if its the Mono-to-Graph primitve in the scope that's giving you a 'fix'. You could try adding a module like this to see if you get the same result.
If it does, and if in particular the problem is only within SynthMaker itself, that it's likely a problem with the sound driver.
But like I said... it's a lot of guesswork going from so little detail.

It's a long time since but I've updated my VST modules lately with the new Synthmaker. The problem is still there but the solution is rather special: I've added the oscilloscope to both outputs of the fractional delays and it works very reliable. The output per fractional delay goes into a multiplication chain and the oscillation does not start ONLY if I add an not used item in the screen. Would love to report it or to show it to you or Malc for investigation?
For the last years I'm very busy with designing hardware based effects. I've learned that 'the degree of freedom' with Synthmaker is much more then programming DSP units. Compliments!! 😉
Kind regards

Yes, I remember helping you a bit with your tape-verb.
Quite a few major changes since you've been gone:
1) Green trigger system has been reworked to prevent feedback. I forget the magic keyboard combo to see where the loopbacks are. Some primitives may have gained auto-trigger-blocking.
2) The stages in DSP have changed; old the default was stage(2), but is now stage(3), & there is a stage(4) also. Stage(1) is still "run once before (?) first sample".
