BIAS FX Mobile turns your iOS device into an incredible sounding guitar amps and effects processor built on the backbone of our award-winning pro-level software. With an easy-to-use drag-and-drop interface, BIAS FX Mobile comes packed with a library of ultra-realistic boutique amps and a studio full of pro-level effects and the hottest guitar pedals.

The BIAS collection of advanced guitar hardware and software is built on the most robust amps-and-effects engine in the industry. BIAS FX Mobile works seamlessly with BIAS AMP 2 and BIAS Pedal apps to allow limitless customization of guitar amps and pedals.

With our penchant for perfection, BIAS FX is built on the backbone of our amazing, ultra-real BIAS AMP 2 tone engine. It’s a radically different approach to tone creation. We joined forces with the world’s top artists, engineers and recording studios to ensure our amplifier circuits are mind-blowingly authentic and best in class. The result? Plug-in for an extraordinary playing experience with realistic touch response and ultra-responsive dynamics.

The BIAS FX universal app includes incredibly versatile, high-quality effects from vintage pedal simulations to newly added high-end rack effects. Mix, match and tweak to enter new sonic territory and create fantastic sounds never heard before. All effects are designed to work with BIAS FX’s easy-to-use, photo-realistic, drag and drop interface to dial in tone just like on analog studio gear.

The BIAS FX mobile app also allows users to connect to our ToneCloud, where players can find thousands of amps and effects configurations created by artists, producers, and engineers from all over the world. You will never run out of inspiration, as the ToneCloud library grows daily. Settings can easily be downloaded and shared.

Super application mais..

Les simulations d’ampli sont juste incroyables il n’y a rien redire.

Cependant j’ai un problème et pas des moindres. Il m’est impossible de télécharger des preset. Le logo de téléchargement est présent mais quand je clique dessus, rien ne se passe.
Si quelqu’un a une solution, je suis preneur !

C’est simple : plus intuitif et plug and play, y’a pas. Le son est de grande qualité et parfait pour répéter et même en concert.

Points bonus pour la gestion midi même si l’assignation est pénible avec le midi commander...

Excellent, mais pas de réponse du support pour régler les problèmes.

Fan de cette appli, j’avais la version précédente, je n’ai pas hésité à migrer vers celle ci et prendre le full pack. Mais j’ai vraiment un gros problème de larsen (casque ou ampli) avec la plupart des préset, que je n’arrive à éliminer qu’en réduisant l’entrée, mais du coup le rendu devient minable.... je n’arrive pas à avoir l’assistance, muette à mes mails. Même sans brancher d’irig, juste L’Appli sur l’iPad avec n’importe quel ampli, celui ci émet un son strident insupportable !!!!
