HEART POUNDING AMPLIFIERS ON THE GO The heart pounding VStomp Amp is now ready to go! Following the development of Hotone’s powerful and versatile XTOMP pedal and based on our proprietary CDCM system, VStomp Amp Mobile delivers organic, studio-grade sound quality and the exact character of legendary amplifiers – just the same as desktop version. PLAY REAL – POWERED BY CDCM SYSTEM Unlike mainstream modeling methods based on the characteristics of a certain “state” of the circuitry, which just “comes close” to the modeled sound, VStomp Amp Mobile employs a complex system based on dynamic feature modeling. In this matrix, every single circuit component is ALIVE and performs like its original. The realness of the amp and effects tones has amazed XTOMP users worldwide, and now you can experience it on the go! Behind VStomp Amp Mobile is Hotone’s CDCM (Comprehensive Dynamic Circuit Modeling) system. CDCM is built on an extremely complex dynamic variation matrix, able to realistically express every detailed change that occurs during the operational process of actual circuitry. This matrix will adjust its own modeling parameters and even framework based on the instrument input signal range, signal frequency, knob position, the instrument’s own impedance, and other variable parameters, all to achieve the closest possible characteristics of actual modeled circuitry. THE ESSENTIALS No complex signal chain. No confusing customization or combinations. You pick an amp model, pick a cab model, add some ambience – it’s that simple! The less you tweak, the more you enjoy: just pick out your rig and ROCK!

Features
Read full description

Cab ML is both a standalone app and an AUv3 plugin that provides a neural network for impulse response generation. By moving tags in a window you can change the impulse response in an interactive way. Underlying a neural network will generate an impulse response based on the position of the tags. Instead of trying out all your impulse response files through a classic impulse response loader, you can now find the right sound interactively by moving the marks until you like what you hear. Furthermore Cab ML also provides a poweramp with many options and a microphone reverb generator. The free version allows you to test Cab ML completely, but every minute the plugin will be silent for 3 seconds. To remove these limits there is a one time in-app purchase. You need an audio interface to connect your instrument to your Mac. Known audio interface brands for guitar or bass are for instance Focusrite or iRig. If you don't have an audio interface, you can use the AUv3 plugin in a DAW such as GarageBand or Logic Pro. Any (guitar/bass) sound you have recorded can be fed through the Cab ML audio unit.
