Hi,

I received my E1 mkII not too long ago and I have been trying to load some presets into a slot using the Web Client using the Controller/Preset Slots tab, except the load won’t occur at all, it hangs without updating the slot at all with the 3 dots moving. I find myself unplugging and replugging the E1, even restarting it but it still won’t work. I have tried on ungoogled-chromium and google-chrome-stable to no avail. Now I am at my wit’s ends and don’t know what to do. What should I do next?

EDIT: one thing of note when watcing dmesg while sending a preset:

[19748.821522] dump\_midi: 23 callbacks suppressed  
[19748.821528] ALSA: seq\_midi: MIDI output buffer overrun  
[19748.821539] ALSA: seq\_midi: MIDI output buffer overrun  
[19748.821546] ALSA: seq\_midi: MIDI output buffer overrun  
[19748.821550] ALSA: seq\_midi: MIDI output buffer overrun  
[19748.821554] ALSA: seq\_midi: MIDI output buffer overrun  
[19748.821557] ALSA: seq\_midi: MIDI output buffer overrun  
[19748.821561] ALSA: seq\_midi: MIDI output buffer overrun  
[19748.821565] ALSA: seq\_midi: MIDI output buffer overrun  
[19748.821569] ALSA: seq\_midi: MIDI output buffer overrun  
[19748.821572] ALSA: seq\_midi: MIDI output buffer overrun

EDIT2: I fixed the above issue by running the following command on my system: sudo bash -c ‘echo 131072 \> /sys/module/snd\_seq\_midi/parameters/output\_buffer\_size’

Now I can load any number of user presets.

Thanks for this, it helped me a lot. Though I had to type:

`echo 131072 | sudo tee /sys/module/snd_seq_midi/parameters/output_buffer_size`

And for it to be permanent:  
`echo "options snd_seq_midi output_buffer_size=131072" | sudo tee /etc/modprobe.d/snd-seq-midi.conf`
