4.3.3.3 “Hotplugging” on Windows
On Windows machines it is possible to experience some connectivity issues between QuNexus
and the QuNexus Editor. This is true for Macs as well, but this issue is much more prevalent on
computers running Windows operating systems.
If your QuNexus is plugged in but the QuNexus Editor is still showing “not connected” above the
QuNexus logo (meaning it can’t find the QuNexus) after you open it, you should try reversing
the steps. First, open the editor, then plug in the QuNexus once the editor is open. In some
cases you just need to find the proper order of operations to get things working right.
If this doesn’t resolve the issue you may want to
try a new USB cable
, make sure you don’t
have any other Audio/MIDI applications open at the same time as the QuNexus Editor (Windows
won’t allow multiple applications to be connected to a class-compliant MIDI device
simultaneously), or try
unplugging other USB devices
.
4.3.3.4 Don’t Send MIDI to QuNexus During an Update
When performing a firmware update, it is
highly
recommended that you do not send MIDI
messages to the QuNexus from another application (e.g. sending remote LED messages from
Ableton Live to the QuNexus). If you do this, the update will likely fail.
Firmware on the QuNexus is transmitted via System Exclusive messages (SysEx), which are
essentially just special MIDI messages. If you send other MIDI messages while the SysEx
message is being transmitted things can get confused and go awry. You won’t hurt your
QuNexus if you do this, but you will have to stop sending MIDI to it and then restart the firmware
update for it to complete successfully. It’s also potentially possible to get stuck in bootloader
mode when doing this.
Note
: this problem is much more likely to occur on Mac OS than it is on Windows, as currently
Windows does not allow more than one application to be connected to a class-compliant MIDI
device (which the QuNexus is) simultaneously. Mac OS does not have this limitation, so you can
be sending MIDI to the QuNexus from a number of sources while the editor is open and
updating the firmware.
4.3.3.5 If Things are Working Fine, DON’T Update Right Before your Show
When there’s a new update available it can be very tempting to get it and update as soon as
you possibly can. While there’s nothing wrong with this urge, if you happen to have a show
coming up anytime soon (or today), it is generally advisable to hold off on updating until after
your show has passed - or at least keep your old versions so you can go back if need be.
While we test everything to the best of our ability, there’s no telling what bugs may be introduced
to your setup - the preset you’re using may have changed in a subtle way that you don’t notice,
there could be a nasty bug that just didn’t get noticed, the new firmware may not like one of your
