Problem Cause Solution
The iCathedral App is not reacting on my external MIDI keyboard, my keyboard works with other apps though. The incorrect MIDI channel assignment of your keyboard Control the MIDI channel settings of your keyboard respectively of its key zones and compare them with the MIDI channels being assigned to the different stops of the actual selected preset. See also: Assigning different MIDI channels to a preset . You also may use our free MIDI monitor app MIDI Wrench to check on which MIDI channel(s) your keyboard is currently sending note events on.
The iCathedral app is playing a different sound than selected by me with the app.

The latency displayed on top of the iCathedral screen is higher than the latency configured by me on the settings screen. This is usually an indication that your system is currently overloaded. The latency displayed on top of the iCathedral screen is the real one measured always in real-time. Please read the section about Latency Configuration and stop other apps from running in background.
