At Superbooth we were ushered into another stunning private studio room just off the Moog Island to take a look at a Beta version of the Moog Model 15 app.
Its essentially a lovingly crafted emulation of the classic Model 15 Modular (some say the best). The iOS app uses the latest tech from Apple - Metal which is an API that allows you to access the GPU directly for better GUI performance as well as leaving more CPU for the important stuff - in this case the sound.
We have to say that it does actually sound very impressive, with that all important audio rate modulation being part of what it can do. And yes you can drive the mixer for some crunch and saturation and drive the filter harder. I'm not an aficionado of the original Model 15 sound, but its got that Moog thing for sure.
Add to that the fact that you can switch it into poly mode to clone the current voice (all identical) for four voice poly, though you will need some later hardware for this and iOS 9.3.1 to get the most from this (iPad Air/2) We hear it totally rocks on an iPad Pro.
Additional good things include 14 bit (or not) CC control mode for mapping your controller, for high res tweaks - actually the Metal API gives you a very responsive GUI for fine tweaking and fast zooming around and cable patching. It will also talk poly MIDI control - so ROLI Seaboard and other enabled hardware can get extra expressive.
There's a built in audio recorder (Audio Copy capable), easy controller mapping, clock-able delay, Ableton Link, and a cool Tutorial mode for annotating patches - all shareable via the standard iOS methods.
A lot of thought has gone into this, under the watchful eye of Moog and arch designer/programmer Geert Bevin.
Its available now on the App Store priced at: $29.99 /£22.99 which is a premium app price, but actually seems well worth it if you have the hardware to take advantage.
