I bought a lot of Reverb in the App Store… I also have a lot of Reverb in Auria Pro… in my iPad, I have Aufx Space, I love its “neutral” colour, and the quality of processing. I also have AudioReverb. I love to use it like an Effect, I mean when I want a huge Reverb, when I want that people can ear it… and now I have also RF-1… when I tried it for the first time, it was on a Drum channel. The preset loaded was Concert Hall. At the moment I pushed the play button I was in a concert arena… Hallucinant! (In French) Amazing! (in English). Wahoo! After I tried it with my guitar, a vocal, on strings… perfect! Then, I started to use the 5 Reverb algorithms: hall, plate, ensembleverb, tremoloverb and vintageverb and load other presets. Then, I realised that RF-1 was more than a Reverb. I mean a "Classic" Reverb. Do you know a Tremolo Reverb in the App Store or in the real life? Do you you know a Ping-Pong Reverb too? (When I launched it the first time, 10' seconds after that I received a redeem code from the developer, I noticed in the IAA version the Tempo setting, the Tap Tempo button version. I said to myself, it's cool, but is it really necessary.... Sure, that it is, as well as the 2 modulation buttons.... Check out the video demo below. Note also that there is a Ableton Link feature, with it you will be able to control within RF-1 the Tempo of another App and be sure that your Tremolo or Ping-pong Reverb will be sync with your drums, guitar or else. All the parameters can be controlled via midi, so no problem for an automation too…) In summary, RF-1 is a versatile effect. If you have a small budget and need a Reverb, RF-1 is a good choice. If you have any problem with your budget, even if you own a lot of Reverb Apps, it’s a good choice too because of the processing quality, because RF-1 doesn’t use a lot of CPU. (Great for an Audio Unit plugins). Because of this Tremolo and Ping-pong Reverberation,! A Killer App! A Must Have!
