More criteria which I always have about plugins in general, especially reverbs:
copy protection and
trial options,
CPU usage,
workflow / GUI and
price. Let me elaborate a bit:
1. Copy protection
I personally just hate iLok. As soon as a plugin uses iLok, I avoid it. I am fair: I did test some plugins already, but in the end I often times was not confinced, though. It's a rather personal, maybe almost ideological thing, I know. I just do not want to support it
(technical wise and worse would be, if I had to buy extra hardware and waste an extra USB slot for this stuff ... I know, most iLok things already work via the iLok account these days, but I still do not like it - e.g. why do they have to know which plugins I own, privacy wise? Sorry for the offtopic now!).
2. Trial option
The best trial option is:
- I want to be able to download the plugin without any account.
- I want to be able to test it without a limitation of days.
- It may mute the sound or end its session after some time.
- It may disable saving presets.
- It may have a nagging screen, reminding me to buy it; totally legit!
The worst thing which can happen is a plugin, I have to pseudo-buy, create an account, get a downlaod which even shows viruses so that I have to double check with virus-total, then I have to register the demo in an iLok account and only be able to test it for 7 days. How ridiculous is that? Companies do not want to have my money after all, like it seems to me. So many barriers ... For example: I switched to Reaper after testing it for the third or fourth time! So in the end, if I am able to test plugins more than just a limited amount of days, I might test it a year later again and even buy it after all.
3. CPU
Somehoe Valhalla manages it so make their reverbs quite CPU efficient. As well as Meldaproductions MTurboReverb or the free MCharmVerb does. This is an aspect I just love. But it's something more in my head, hehe. Still: if there are reverbs which eats 10% of my i9 9900K, I just remove it and try to forget about it. :D ... call it OCD-ish, what it partially is, to be honest.
4. Workflow
The reverb should have quick options to set it up as I want. No tiny GUIs knobs which move unexpected or so. That's why I began to like ValhallaPlate as well, btw: a veeery big knob for the main control: the decay time. It's just a clever GUI, imo. I really love the concept of Pro-R as well, by the way. Unfortunately I did not like the sound bakc then when I was able to test it, which I am not any more, since it only has a limited days to test it, ARGH!
5. Price
If the reverb fulfills all the above points in a positive way, it might even be regardless what price it has in the end. And then there is Valhalla with its cheap prices and fulfulling all the above points.
BUt still: a lower price can be tempting here as well, of course.
Sorry for the long post ... should my post had become a separate thread in the end?
