Pretty bad software, everything sounds crunchy and underpowered.
It's like buying 100 watts speakers and using a 1 watt amplifier. No matter how much you turn up the gain, the feedback is poor and the sound just gets muddled.
I have their IK Multimedia AXE I/O that I'm using with another amp simulation and everything is great, good signal levels, powerful distortion and gainy presets. The instrument sensitivity is insanely good. The signal levels are strong and have a consistent body.
Same audio interface and IK Multimedia Amplitube 5.... complete disappointment.
The problem is the Amplitube software itself. The audio interface hardware is top notch.
No use making excuses about what gain goes where... This software SHOULD WORK perfectly out of the box.
By simply selecting an amp head and a cabinet, that's supposed to be modeled after real amps from the real world, the sound should be well amplified and have the correct instrument feedback.
I will have to accept the fact that I wasted money on poor software. They really need to investigate and fix the signal levels and processing.
Until then, I'll stick to my other software that I cannot name here.
Important note: if you select a default preset that has a module that you do not yet own, they programmed the software to insert rhythmic hissing noises. This is something that they do not tell you, I had to look online to understand what is happening, when they could have programmed a pop-up to warn you that you do not own a specific module.
In conclusion, it's a poorly designed and underpowered modeler that's happy to sell you other modules.
