If you have V-Collection 5, the you have the full individual applications.
Automat is a Matrix 12 sound. Matrix 12 don't work well with normal sustain function like you can see i have reported here:
https://forum.arturia.com/index.php?topic=88716.0It's possible to create a sustain effect in Matrix 12 modulation matrix by modulating envelopes. That is the normal way to do it in Matrix 12.
As it is now, then if you only switch on the "Sustain" button in Matrix, then you will here no new notes when you have used all avilble voices.
I suggest you look in Matrix 12 forum to see other issues. There for example is a playmode retrigger issue.
I hope Arturia will get all things fixed very soon. I think they allready should have been.
If you by Rhodes mean Stage-73, then i suggest you look in Stage-73 forum. Arturias applications have for example pretty much in generel issues with delay.
To check if your issue is preset specific, i need to know the excact preset. It can be a setting. Specific informations important in generel.
This is what i can add now to my previous post. Like i mentioned, then i too seems to have issues with Analog Lab 2 Multis. It's no good to have to add presets to a multi again everytime you wan't to use it.
