I just learned about aggregated devices on mac and as i have both a QC, a Hx stomp and an Audient id4 that i use from time to time it struck me that if i record a riff i my daw from one of my bands presets… then switch to the Hx stomp that is my backup when playin live, i can use the recording for tonematching my hx stomp presets and get it as similar as possible. 
Anyone else have any tricks up theire sleeves?
