I have used Positive Grid
I have used Positive Grid software since the first Bias FX and have used Bias FX 2 since it came out. I have owned the original Bias Head modeler and the Spark, and I have also used Bias Amp 2. I purchased Bias X hoping it would be a genuine upgrade to Bias FX 2, or at least a worthy successor. It is neither. I completely regret purchasing it.
The presets are absolute trash, and creating a usable one is, putting it mildly, an unpleasant chore. There is nothing here that is better than Bias FX 2, which itself already came with plenty of caveats and frustrations.
The AI feature is even worse. It does not appear to meaningfully analyze an audio file to match the tone. Instead, it seems to read the file name and then generates something that only vaguely resembles it, as if the tone were being played through a very old telephone that had been shaken inside a can of very angry bees.
I fed it a file of a metal track which apparently shared its name with some kind of jazz tune, and it generated a jazz preset. When I asked why it did that, it started spouting Chinese characters, which did not inspire confidence and only left me confused and questioning several of my life choices.
There is also no ToneCloud or anything comparable, which makes the whole thing feel even more barebones and half-baked.
I also noticed that any reference to Bias FX 2 has been completely removed from the Positive Grid website, which makes me suspect it is slowly being put out to pasture. That would be a shame, because for all its flaws, it was still the closest thing Positive Grid had to a decent software offering. Even then, it often felt like updates existed mainly to fix whatever the previous update had broken.
I actually reached out to customer service after trying Bias X and raised the concerns above. The response was the corporate equivalent of “meh, whatever,” stretched across enough words to sound polite while saying essentially nothing.
I will not be putting any more time, money, or effort into Bias X or Bias FX 2, and it is with a hint of sadness that I watch Positive Grid trade “mostly okay” for actively disappointing.
