Waveform~ bug?

Jul 08 2010 | 10:11 am

Here’s an odd one. I have a patch which contains two waveform~s to display the same buffer. One displays the buffer contents as expected, the other doesn’t. Even if I hit the ‘set sample’ button it will not display in the second waveform~.
But if I paste-replace the waveform~ with a new instance, it will display ok – until i save & re-open the patch, whereupon the problem re-appears.
Unfortunately, this does not happen if I copy/paste the relevant bits of the patch, as I have below, to Illustrate the problem, so you’ll have to download the original to see the problem.
In fact when I copied the waveform~, which had been blank in the original patch, it pasted into the new patch displaying the buffer as it was supposed to.

Steps to re-produce:
1. Download the second of the two patches in this thread
2. Open the patch and click the ‘load buffer’ button; the waveform should appear in both waveform~s, but only appears in the top one.
3. Unlock patch, click the ‘set sample’ button for the empty waveform – nothing happens.
4. Create a new instance of waveform~ and past-replace the empty waveform~. Click ‘set sample’ – waveform displays OK.
5. Save and reopen patch. Waveform~ bollixed again.

Hi roger, I had the same problem with 3 waveforms and 2 buffers, none would display properly! it only works if i delete the waveforms and create them again, which is a pain in the arse!

I’ve emailed the support about it, its probly a bug i think, so im waiting for them to get back to me about it. Il let ya know if they do!
