does Patchbox OS work o raspbrry zero/w hardware?
I´ve got a USB Hub mounted on my zero/w and connected a wireless keyboard/mouse and a hdmi monitor: It shows me only a raspberry and a frozen cursor on boot.
(I´ve tried also an edit of the cmdline/txt as suggested in another thread with no result:
# Add the following options:
dwc_otg.fiq_enable=0 dwc_otg.fiq_fsm_enable=0 dwc_otg.nak_holdoff=0
Try first installing non-realtime kernel on Raspberry Pi 2 - 4, as suggested here: PI Zero W hangs when booting with USB keyboard
sudo apt install raspberrypi-kernel
so I have to install the non realtime kernel with the standard raspbian OS and then reinstall Patchbox OS?
(I´ve got no other Linux devices)
and I loose performance then, as mentioned somewhere the latency increases from 200us to 5ms
I wonder if that is good for routing realtime MIDI on 4 Synths??
You have to first run Patchbox OS on Pi2 - 4, and install the non-realtime kernel.
The latency depends on what exactly you measure. For USB MIDI and DIN-5 MIDI, expect latency around 1ms - 2ms, as established by the USB and DIN-5 serial transport limitations. Non realtime kernel (as slow as it sounds) won’t impact latency that much.
Anyway, you should consider using higher performance Raspberry Pi models if latency can be an issue. The Raspberry Pi Zero is more aimed at space-constrained and low-cost applications than high performance processing.
