### 5/5 — Thanks!

*2020-03-07*

### 1/5 — And this makes two

*2019-11-01*

This is another one of their apps ..it doesn't even work properly in fact this one won't even work at all as soon as you press any keys it just crashes on you in cubasis.I was actually thinking of buying more of these apps but I would definitely not now that is two that are not even working...Just found another problem with this there is no automation working in cubasis.Luckily I backdated to an earlier version one where it wasn't crashing

### 5/5 — Great Reverb Effect

*2019-07-03*

Can’t go wrong with Kai Aras and Numerical.

### 5/5 — Good Reverb

*2017-01-20*

Reverb is really smooth. Plus you add the fact that it's Interapp as well as Audio Units, you can call up to different verbs from your DAW at the same time. Nice. Not sure why more apps to implement Audio Units

### 2/5 — 堀さん

*2016-12-31*

低品質というわけでは無いが、わざわざ単品で買う程のクオリティは無い。

### 5/5 — Superb AU enabled Reverb

*2016-10-31*

There are lots of Reverb FX apps available, but few able to match the subtle controllability and quality tones produced by this one. Great price, too.
