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.
