Hi! I'm trying to copy the functionality of LoopPi2 (https://github.com/szymonkaliski/LoopPI2) on Orange Pi Zero. The advantage of OPi Zero is that it is very inexpensive and has an audio codec built-in, which makes it even less expensive. I have the audio side of things working ok on both the recording side and the playback side, however all Chuck scripts work very slowly. The computer has a 1.2 GHz processor and 512 megabytes of memory, which is not much but today's standards, but you would think it's enough for some audio work.

Observations:
1. Setting the rate to 8000 helps some, but it's still choppy.
2. At least looking at 'top', Chuck doesn't ever use more than half of the CPU. There's nothing else on that would use it, I don't even have a graphical UI of any kind.

I'm using Armbian Debian Jessie with kernel 3.4.113 because I had some trouble with MIDI on the mainline kernel. I compiled Chuck myself from the 1.4 sources. I don't know if I missed some optimization step.

Chuck runs on the original Raspberry Pi, which is a lot less powerful and otherwise quite similar, so I don't understand where the trouble comes from.

Regards,

brkl

Hi,

unfortunately I have no experience with OrangePi. I would like to suggest you to write on the official mailing list as well Wink
