   * there's a set of dummy pads if you want the line of resistors to look symmetrical, it's just for show :)

-  * 48* 1N4148 diodes. Note carefully the alignment of the cathode band. The top two rows point "north", while the bottom two point "south." If you get any of these wrong, the switches will not work.

   * 64* LEDs, cathode marked by the flat part on the silkscreen. As noted, usually you will have 16 red and 48 green or other colour options. If you intend to build an opaque case, you may wish to install them "proud" i.e. only soldered once they're pushed up into the panel. For transparent cases, it's fine to mount them "flush" to the PCB.
   * 48* switches. See part notes above. You can use different colours to help identify the different functions.

+This file should be uploaded to an STM32F4 Core
+The config file MBSEQ_HW.V4L should be copied to the root of the SD Card used. [[http://svnmios.midibox.org/listing.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fsequencers%2Fmidibox_seq_v4_lite%2Fhwcfg%2Fsrio_v4l%2F|It can be found on the SVN repository]].
+At some point these should be made available in the normal MIOS32 download section.
+A sessions folder will be created on first use if one doesn't exist. If you're having trouble with the MIDI Input, please open the SESSIONS/DEF_V4L/MBSEQ_C.V4 file and change:
+MIDI_BUS_Options 0 0x00
+to
+MIDI_BUS_Options 0 0x01
