This unique virtual instrument introduces a new “Audio Model” format, capable of containing thousands of waves extracted from ordinary audio files. These waves - and how they’re structured - lays the ground for how Tomofon generates audio, resulting in a highly flexible and instantly expressive instrument. On one hand it can sound very organic, even lifelike, and on the other, like something out of this world. Whether you want to play around with the Audio Model Starter Pack (instruments & voices) and factory presets, or import your own audio to shape your own unique soundscapes – it is fair to say that you are in for a creative journey. How does it work? Tomofon converts audio files into a large set of oscillating waves, which are then mapped into pitch zones where each wave represents one layer (a bit similar to how a sampler structures different velocity zones). The main difference is that since each zone is populated with waves instead of ordinary samples, the synth engine can morph between them (both layers and zones). This makes all transitions between zones and layers continuous and seamless. Create and share your own unique sounds A significant feature of this plug-in is that users can import their own audio files and create new and unique Audio Models. Ordinary audio files (preferably with monophonic content) can easily be imported and distributed into different pitch zones over the keyboard range, either automatically or manually. Doing an automatic import is basically a one-click process which instantly results in a proper playable Audio Model. A manual import gives the user full control of which waves should end up in which pitch zone. Last but not least you can easily share your own created Audio Models with others. Tomofon comes pre-loaded with a pack of 124 Audio Models based on high quality audio recordings of multiple expressions. These models includes several instruments like strings, vocals, brass, woodwind, guitars and more. Along with these models there are over 180 presets to get you going right away. From there on you can venture further and start creating Audio Models based on your own audio files and experiment on the types of sounds they can grow to be. Features - Wide selection of factory presets and Audio Models - Integrated audio sample importer and Audio Model editor - Pitch and (layer) depth envelopes that can be edited by the user - Envelope times can be controlled separately via MIDI velocity - Several LFO:s (including Sample and Hold with randomness) - Modulation matrix (2 x MIDI CC, Velocity and Keymap) - Monophonic playback with separate glide times for pitch and velocity - Polyphonic legato playback where started notes syncs envelopes with currently playing ones - Up to 4 doubling voices with separate pitch, pan and level - Filter with modulation possibilities - Post Reverb, Delay and EQ

FabFilter Pro-R 2 is a high-end reverb plug-in with natural, vintage and plate algorithms, combined with intuitive controls. Its advanced algorithms have been carefully designed to blend well with the source and fit easily into a mix. Pro-R is bursting with innovations like the intuitive Space control that seamlessly switches between dozens of room models with automatic decay time adjustment, and the unique Decay Rate EQ that introduces free adjustment of the decay time over the frequency spectrum. Together with the built-in Post EQ and a large number of high-quality factory presets, FabFilter Pro-R 2 delivers great sound quality and is very easy to use. The Pro-R 2 app filters the microphone input and plays it back in real-time. To use Pro-R 2 as a plug-in, you need an AUv3-compatible host app like Auria, AUM or Cubasis. Pro-R 2 will appear in the list of Audio Unit extensions for effect plug-ins in the host app. What's new in Pro-R 2? - Brand-new Vintage and Plate algorithms that recreate classic reverb sounds - Thickness control to thicken, compress and saturate all at once - Auto Gate feature to easily get that gated drum reverb sound - Built-in Ducking to allow the reverb to blend in better with the source material - Import IR feature enables you to import an impulse response file (WAV or AIFF) and sets up the reverb and EQ bands to match it - Surround/immersive support in hosts that allow this - Mid/Side and Left/Right options for Post EQ bands - Output level metering - Redesigned, full-featured preset browser Key features: - Beautifully designed room models, ranging from small ambiences and rooms to large concert halls and huge cathedrals - Carefully developed to easily sit in the mix, without causing undesirable coloration, density or phase problems - Gorgeous Retina interface with large interactive reverb display featuring Decay Rate EQ and Post EQ curves - Very easy to set up, with user-friendly, non-technical controls - Space control, which smartly and smoothly combines the room model and decay time of the reverb — choose from over a dozen carefully designed room models and seamlessly vary between them, without hearing clicks or unwanted artifacts - Decay Rate control, changing the overall decay time from 25% to 400% of the current Space setting - Intelligent Stereo Width control, ranging from pure mono to true stereo and beyond - Distance control to adjust the proximity to the sound source in the selected space - Character control that changes the sound from a clean, transparent decay, to a lively reverb with pronounced reflections and echoes — all the way to an over-modulated chorus-like effect - Perfectly tuned Brightness knob, affecting not only overall brightness, but also the decay of high frequencies - Predelay knob, ranging from 0 to 500 ms, with optional tempo sync - Innovative six-band Decay Rate EQ, with Low/High Shelf, Bell and Notch filters. (Compared to the commonly used low- and high crossover system, the Decay Rate EQ opens a world of possibilities by giving you full control over the decay rate at different frequencies.) - Six-band Post EQ to equalize the final reverb sound with Low/High Cut up to 96 dB/oct, Low/High Shelf and Bell filters. (Together with the Decay Rate EQ, this lets you design reverbs of any style or character.) - Real-time spectrum analyzer that also visualizes the decay time at different frequencies - Includes a carefully curated collection of factory presets - Save, restore and organize your own presets - Undo/redo and A/B comparison "Pro-R sounds awesome and is hugely enjoyable and rewarding to work with. Verdict: 9/10!" — Computer Music Magazine "Pro-R is yet another demonstration of the worth of FabFilter's distinctive vision for plug-in design" — Sound On Sound Magazine
