Hydra 1.5 crashes DAW when opening interface

[magicalplug]

Hi,

I'm using OS X 10.11 and Reason 11.3.9. The previous version of Hyrdra works 100% fine but the new 1.5 version released last month causes Reason to crash instantly when I try and open the plugin's interface.

I wondered if it was because of the new upgrades which include Apple Silicon support but I'm also a Dune 3 user and have upgraded that to the brand new v3.53 and that works on my system without any problem.

I think there's something in the new UI code in Hydra which disagrees with Reason.

Are you able to provide an update to Hydra which will be compatible with my admittedly quite old Apple Mac and Reason 11 combo and will let me open the new plugin's interface without it crashing and taking my DAW down with it?

Please let me know.

Many thanks

[Marcin]

Hi, is there any crash report shown after the crash? If so, please send it to us.
Also are you able to check other VST 2 host and check if it crashes at there too?

[magicalplug]

I don't have any other VST2 hosts but I tried an AU host and it did the same thing; completely crashed when the plugin interface was opened. I looked in the Crash Reporter logs and both Reason and the Hosting AU app crash with the same error:

I hope that is useful and you can work out why Hydra 1.5 interface is crashing on my machine and fix it. Please let me know if you need anything further.

[Christophe]

It is working with Windows 10 and Reason 11.3.9

[Marcin]

@magicalplug - we have sent the message (e-mail) to you containing the link to the new test build of the Hydra 1.5.
Please let us know if the crash is gone.

[magicalplug]

Hi Marcin, I've tried the version you sent over and it fixes the crashing! The new larger sized skin makes working with the synth much easier. The knobs look a little blocky/pixellated now compared to everything else in the interface but everything is working fine. Thank you so much for fixing this for me.

Hi Marcin, will you be issuing a new official version of Hydra that contains your bug fix, or am I OK to keep using this test build you sent me?

[Marcin]

The bugfix build has been published already in the User area.

Great! Thanks Marcin
