THNDRVERB is a flexible algorithmic reverb processor for your personal needs for room shapes with various reverberation types. This is your new Reverb-companion effect for Reason Rack. The main section of this device is the ALGOVERB section. It includes 25 categorized reverberation modes from classical rooms and halls to various places and well-known hardware reverberation algorithms. It includes Rooms, Halls, Plates and Places. All ALGOVERB reverberation modes are algorithmic reverberations, no one IR impulse is used. ALGOVERB can be used in Main Only mode (when all other sections is disabled), or in Parallel and Feedback modes with the next sections: Main & Feedback Tone, FeedVerb, FeedShift and Magnet 8- Head Tap Delay.The TONE section helps to improve your signal for the Main and Feedback routing with Low/Mid/High settings like Mid EQ, LP & BP filters, control of reverb time scale at Low frequencies, progressive loss of high frequencies at the reverb tail. FEEDVERB section is an additional Reverberation section for Parallel or Feedback signal processing. It is based on 7 algorithmic reverberation types with High frequency Tone loss at FeedVerb tails, Mid band EQ and Pitch-Modulation of the reverb for a richer sound.
