Hi DrumHazard,
There are two ways to use AeroDrums:
1. Audio - AeroDrums software + virtual audio cable software
2. MIDI - AeroDrums + drum VST plugin inside jammr
The AeroDrums user manual has information on how to set up MIDI:
https://aerodrums.com/manual/#midiThe audio approach means that jammr will hear the sounds produced by the AeroDrums software. The MIDI approach means you can pick any available drum VST instrument that works inside jammr and you won't use AeroDrums to produce the sound of the drum.
Both of these approaches are a little technical to set up because they require additional software to connect AeroDrums to jammr. The easiest way to get started is with the audio approach: try virtual audio cable software (like VB-CABLE on Windows or SoundFlower on macOS) and connect the AeroDrums output to the jammr input.
