There were a couple of presets for the new H9 EQ Compressor algorithm that added a lot of gain to your signal which could be useful for overdriving your amp. We thought it was a bit dangerous to have these as Factory Presets because you couldn't delete them or turn their gain down. So, we posted new builds of H9 Control for MacOSX and Windows that removed these presets, and as soon as this new build is approved by Apple, they will be removed from the iOS version of H9 Control as well.
We have posted these presets online though, and after downloading them, you can import them into H9 Control by clicking on the Settings button in the bottom right hand corner of the app and going to Import Presets. The advantage of making these presets available this way is that they will be user presets, which means you can delete or modify them to your liking.
