RF-1 goes desktop – Numerical Audio launch desktop version of their popular iOS reverb app

Download from iTunes App StoreI reviewed the excellent RP-1  and RF-1 apps from Numercial Audio developer Kai Aras here on the Music App Blog when when both first launched. They provides compact, but well-featured delay and reverb effects respectively and both are capable of conventional and more creative treatments.

For the iOS musician, both RF-1 and RP-1 are universal apps, requires iOS9.0 or later, are approximately 30MB downloads and are individually priced at just UK£5.99/US$5.99. However, on a technical front, perhaps the best bit is that both apps include Ableton Link and Audio Units (AU). The latter means that you can, of course, run multiple instances of the app within a suitable AU host such as MultitrackStudioCubasis, Modstep or AUM.

Anyway, developer Kai has kept the pace of development going and both apps received regular updates on the App Store. However, something different came along back at the start of August; RP-1 arrived on the desktop with a Windows/OSX plugin version of the delay app appearing. I gave it a quick spin here and was suitably impressed. It matches the iOS version pretty much exactly in terms of features and sounds great.

RF-1 goes from iOS to desktop to join RP-1…. and sounds just as good there.

The desktop version is available for both Windows and OSX and can be purchased directly from the Numerical Audio website. The full price is €29 (probably around UK£30/US$30 given current exchange rates?) but, if you get in quick, there is a special launch pricing of just €15. That’s App Store pricing for a desktop plugin….  and there is a demo version you can download to try out on your own system before purchasing.

I’ve been able to give the desktop version a quick spin on my OSX system this morning using Cubase 9 as my VST plugin host and RF-1 worked very smoothly. As with RF-1, the feature set and UI look similar to the iOS version. That’s a good thing because the iOS version is excellent. This is a cool – and very useful – reverb effect.

The desktop version ships with a good selection of presets.

There is little not to like about either RP-1 or RF-1 under iOS and, with both now on the desktop (and just as good), Numerical Audio are clearly keen to expand their product line. It is also great to see products that started life under iOS making a successful transition to the desktop….  If you have not yet given the iOS versions a go, then at just UK£5.99/US$5.99, either app can be seen as a pocket money purchase. No fuss to use, they sound great and are very affordable.
