The CC:0 and CC:32 commands are bank MSB and bank LSB, they mean the same thing!
The BeatBuddy as of 4.1.1 expects an MSB (CC:0 values 0-127) + LSB (CC:32 values 0-127) command to select the folder by default, and the PC command selects the song. If you already have the folder you want open, you only need to send a PC command.
Aeros Mode on the BeatBuddy makes it so you only need to send an LSB command to select the folder and the MSB command is negated. In 4.0.1 it works like this by default but it is a setting in 4.1.1.
MSB and LSB are typically followed by PC when they are used as a string, which is common among other products that are not ours.
We cannot facilitate every setup, unfortunately sometimes you need to invest in products that can do more than what you currently use to get the most out of our devices.
There are other ways to song select handsfree using the external footswitch.
Thank you for your feedback!
