Some of the original factory presets have been corrupted. Kairatune has gone through a lot of internal changes over the years, which has required remapping the factory preset parameters to new values. Unfortunately some of these, mainly the EQ types, have flipped to the next or previous option unnoticed.
To give an example Airy Rubber Keys and Welcome are some of the affected the presets. There are probably more and the seriousness varies. Flipping a low pass EQ to high pass without changing the cutoff will impact the sound.
Here are the first impressions by MarcFreccero from ZigZag Production Studio. We got 4.7/5 overall score, despite the fact that we failed the test on the find the init/reset/new-preset button to start designing a fresh.
