  • MIDI Learn assigns continuous controllers to any switch or knob in BIAS FX

Here’s what they have to say about it:

BIAS Amp Integration

BIAS FX Desktop opens up a whole new level of performance and recording: dual amps replicate the huge tone of two real amps set up together; dual signal chains provide 2 fully independent effect paths running in parallel.

And when integrated with BIAS Amp (available separately), users can select a different preamp, power amp, cab, mic and eq for each of. But the tone doesn’t end there: users can also download any Amp Match models from BIAS Amp, accurately capture any real amp tone, and run them in dual amp configurations to create a never ending amp tone creation tool.

Thousands of rigs from the cloud

ToneCloud allows musicians to share and download thousands of user and artists rigs right from the cloud. Positive Grid continues to work with producers, engineers, and world class artists to create an ever growing tone library of amazing sounding rigs. Signature ToneCloud presets include Ola Englund, Rusty Cooley, Mark Holcomb, Stephen Carpenter from Deftones, and the latest addition to Positive Grid’s roster, guitar sensation Tosin Abasi. Users are able to perform, record, and re-amp using any of factory, user, and ToneCloud presets in BIAS FX.

BIAS FX Desktop is now available for $99 (BIAS FX), $199 (BIAS FX Professional) and $349 (BIAS Pro Bundle).

One thought on “Positive Grid Releases BIAS FX Desktop Cross-Platform Guitar Amp and Effects Processor

  1. Bias desktop is probabaly the best guitar amp sim plugin out there, and I’m glad it’s getting FX finally. Though that price is pretty high when you consider that most other amp sims already include FX.
