IMPULSation is an impulse response/convolution reverb that allows you to load in your own impulses for an an unlimited amount of neverb and amp possibilities. To give you an idea of the power of this app: There are literally hundreds of thousands of impulses freely available online and our app will load them all, given that it’s properly formatted in either .wav or .aif format. Say for example you have an electric piano sound that you want to run through a classic Fender™ AMP. You do a web search for “Fender AMP Impulses” and pick from the thousands of possibilities. You will literally spend hours upon hours freely downloading all of the available spaces, amps, reverbs, and/or delays to use within your favorite AUv3 DAW. The technology of convolving and deconvolving is a method of putting in a signal through an amp, reverb unit, delay unit, or space and with sophisticated mathematical interpolations techniques, you can create a very close replica of the actual source. Our IMPULSation is specifically designed for AMPs, reverbs, delays, and spaces of which our code is optimized to detect which is being used. The detection allows us to optimize the signal for better CPU and for optimal sound. As with all of our other apps, our goal is always simplicity with power. We give you all the important features needed for a great sound, without being too complex. The features are as follows: NEW UPDATED FEATURES: ▪ BlueTooth MiDI Capable ▪ iCloud Backup and Sharing of Presets ▪ Enhanced AUv3 Preset Resizing ▪ Expansion Pack Banners and Branding ▪ Metal support, Faster UI, Faster loading, and major CPU Updates ▪ Two Mode MIDI Program Change General Features: - AUv3 - AAX - 88 Factory Presets - The ability to load in your own impulses using the iOS files app (Works With External Drives via iPadOS) - MIDI Learn parameter **SPECIAL NOTE: Importing works by selecting a folder with .aif or .wav files in it and all of the files will be imported from that folder. App Controls: - Pre-Delay - Wet Controls with Range control for precise scaling - Dry Controls - Decay Controls - Waveform View - Stereo Widener that enhances pre-stereo signals - Master Output Includes Over 200 Impulses from very popular vintage reverb units: - LEX200 - LEX480X - RLND RE201 - RLND DEP3 Echo - EMT 244 - NBA Lush - ASR-10/DP4 - Exotic Places - Special FX ------- ATTENTION iFX Rack Users: 1.

Please note: this is an AUv3 plugin that can be used with compatible host Apps. TimeVerb-X is a new plugin from GSi that combines GSi's “classic” Type4 spring reverb, first released in 2008, and a new algorithmic digital reverb. The “Type4” spring reverb emulation was originally inspired by an Accutronics reverb tank type 4, like those used in classic Hammond organs of the A100 series, also used in many famous electric guitar amplifiers. The digital reverb, instead, was first developed for the GSi Gemini sound module, but was also included in some Crumar hardware instruments. Both effects have been slightly expanded and further improved for the release of TimeVerb-X, as the spring reverb now features a self-oscillating feedback decay adjustment and a stereo width knob, and the digital reverb includes the early reflections section that was missing in the original project. Both reverbs put together make up a great sound when working in parallel, and create some interesting atmospheres when working in series. TimeVerb-X main features: - Spring reverb "Type 4" with feedback and stereo operation - Digital reverb with pre-delay, early reflections and room size adjustment - Built-in programmer with unlimited number of Programs (comes with 16 factory Programs) - Integrated user's manual - Comes with AUv3 extension
