Both of these are very capable audio processors in their own right but, given the desire from many iOS musicians to see the AU plugin format really take hold, the fact that both are also available as AU plugins only is also of considerable interest.
6144 EQ is a AU-only format equaliser plugin whose inspiration was the highly regarded Neve 5033 hardware EQ processor. Envelope Reverb is perhaps less directly related to a specific bit of original hardware but it provides a very good algorithmic reverb effect. Both apps worked very smoothly for me when used within AU hosts such as Cubasis and AUM.
Anyway, Envelope Reverb received a minor update over the week-end taking the app to v.1.0.2. There is nothing drastic in the update itself – a minor graphical change to make the colour scheme a little easier on the eye and a change to the default wet/dry setting (it’s now set to 50%) – but it’s good to see DDMF continuing work on these existing iOS apps. And if you haven’t checked out the original reviews of either 6144 EQ or Envelope Reverb then do so…. both a very good and well worth a look.
If Envelope Reverb and 6144 EQ are a sign of what’s to come under AU for iOS, then I think we have a lot to look forward to. They promise the convenience of the desktop workflow along with a pretty good stab at the performance of their desktop equivalents. DDMF have other desktop plugins in their catalogue…. based on the iOS ports so far, I really hope that others might follow. Envelope Reverb comes highly recommended.
