I've bought a couple of your devices (great tools, thanks!!), but Live10 crashes if I insert this Conv-Vel 1.4 after Render-Vel 1.2 ("A serious program error has occurred. Live will shut down after this message box is closed").
I can insert separately Render-Vel or Conv-Vel without problems, but if I use them together (Conv after Render) the crash message pops up.
Is this a bug?

Thank you for your purchase. I also tested it and I ran it for a while, but I could not see similar bugs. Give me some more information to resolve.
?mac or windows (and os Version)?
?Live Version (ex 10.0.2)?
?Will it fall at the moment of insertion after Render?
I apologize for causing trouble but thank you.


latest Live version, win10 1803 64bit, it crashes at the moment of insertion after the Render.
But I noticed that it also crashes if I insert it before the Render, and also if I remove the Render and insert the Conv in the same track or in any onther track of the Ableton project. Same thing if I remove all devices and insert the Conv again; on the contrary the Render can be inserted and remove without problems.
I don't know what it is, but it seems like an object or something that is locked/used by the Render and the Conv can't access it; so if I insert in the track the Conv and the Render in a second moment it works (just for this one track), but every other combination results in the error/crash.

Thanks for your work, have a nice day.

Updated to Ver.1.4. Please try it with the new version.


Hey! Thank you for the update, the crash is gone now, but unfortunately the device's GUI is blank/white:

Oh, how terrible it is.. I updated the latest version to 1.5.1 now so please check it again. I'm sorry for troubling you.

It's strange, now the 1.5.1 GUI is ok but the crash is back again. I don't undestrand, if I try to load 1.5 it doesn't crash (but it is blank/white), but back with the 1.5.1 the bug starts over. GUI problem/crash?? Really strange

I see. Probably the cause seems to be Render-Vel, not Conv-Vel. Wait a moment as I will fix Render-Vel. Thank you.

Hi, with new Render-Vel version 2.0 the crash is fixed, thanks a lot!
