this is where it's messy. The encoder interrupt runs in the background adding + or - increments, Every 100 ms, the encoder count is retrieved, and a volume command is sent if there was a change. So I would need to add dampening to the interrupt, which I did for buttons, but I need to check the behavior with encoders. > Can I just check a previous detail?

Apologies if you're aware of this - I > know that version was only a proof of concept etc. I've only been talking about the pigpio version. I've not tested with 2 buttons, can you show be a trace with 2 buttons, and long an short presses of each button. piCorePlayer a small player for the Raspberry Pi in RAM.
