 ======Building a SEQ V4======
+[[http://midibox.org/forums/topic/19029-mididocs-building-a-seq-v4-discussion-thread/|Forum Discussion Thread]] - for comments, corrections, or questions about this article
 If you're new to the MIDIbox universe, you might be a bit confused about how to actually build one of these things.  What PCBs and parts you'll need, where to get them, etc.
 All of the MIDIbox projects are fairly advanced DIY projects.  If you have no experience soldering and sourcing parts for an electronics project you may want to start with another more straightforward DIY electronics project.  Building a [[http://mutable-instruments.net/shruthi1/build|Mutable Instruments Shruthi-1 synth]] might be a good place to start - they're fairly beginner-friendly.
+Hawkeye has put together a very detailed [[http://midibox.org/forums/topic/18868-building-a-midibox-seq-v4-wilba-control-surface-photo-tutorial/|photo tutorial]] on how to build a SEQ V4 with Wilba's Frontpanel in the forums.  You should check that out.

 So, to build a basic MIDIbox SEQ V4, you will need:
-  * Either a CORE_STM32F4 or a CORE_LPC17 PCB;
+  * Either a CORE_STM32F4 (with MIDI I/O board) or a CORE_LPC17 PCB;
   * Wilba's Frontpanel PCB;
   * Two 40x2 LCD displays;

 The BOM for the Wilba Frontpanel can be found [[:wilba_mb_seq_parts_guide|here]].
-You can buy your parts wherever you like to buy parts.  [[http://reichelt.de|Reichelt]] and [[http://www.farnell.com/|Farnell]] are apparently good in Europe.  [[http://www.mouser.com/|Mouser]] and [[http://www.digikey.com/|Digikey]] are the big ones in the US and Canada.

-It does take some time to receive your order from MIDIbox-shop.com.  Tim's busy with other things, and given the low prices in the store, I'm sure he's not raking in the cash from this venture.  Place your order, and be patient.  It may take anywhere from three weeks to a couple of months to get your order (but you will get it eventually.)  Tim posts order/shipping status updates [[http://midibox-shop.com/status.html|here]].

 You'll want to buy either (a) a Core STM32F4 + MIDI_I/O Module PCB; or (b) a Core LPC17 Module PCB, as well as a SEQ_CS PCB (Wilba's Control Surface Frontpanel).  You'll also probably want to get 17 rotary encoders, some IDC connectors and ribbon cable, some midi jacks, and maybe some LEDs from MIDIbox-shop.

 ===Case===
-You don't need a case.  My SEQ V4 is currently just a couple of bare PCBs mounted on standoffs on a piece of plexiglass...  Build costs go way down if you don't need a case.  I'll probably build a case for mine once I finalize its configuration, and decide what add-on modules I want to incorporate, etc.

 If you want a case, there are many options available.  If you build Wilba's Frontpanel with the switches and caps specified, there are [[http://midibox.org/forums/topic/17127-lasercut-acrylic-case-frontpanel-for-seqv4/|laser cutter templates]] that you can send off to your favourite laser cutting establishment.  Sometimes there are group buys organized for [[http://www.midibox.org/dokuwiki/doku.php?id=seq4_aluminium_case_and_frontpanel_2014|aluminum]] or other fancy cases.  Check the forums.

 If you're using Wilba's Frontpanel or some custom layout, the SEQ won't work if you don't put a hardware configuration file on the SD Card that assigns the buttons and LEDs.  You'll need to put this [[http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fsequencers%2Fmidibox_seq_v4%2Fhwcfg%2Fwilba%2FMBSEQ_HW.V4|MBSEQ_HW.V4]] file in the root of the SD Card.  If you're using a custom frontpanel, you'll have to write a custom MBSEQ_HW.V4 file, but if you look at the file linked above, you'll see it's pretty well commented.  If you're building your own frontpanel, you'll probably be able to figure out the config file.
+You'll have to flash the [[http://www.ucapps.de/index.html?page=mios32_download.html|MIOS32 (MIDIbox Operating System)]] firmware to your Core.  Download the latest [[http://ucapps.de/mios32_download.html|SEQ V4 firmware]].  Choose the right version for your MIDIbox Core.  Unzip the firmware, and upload the project.hex file from the zip to your SEQ using [[http://ucapps.de/mios_studio.html|MIOS Studio]].
 ====Adding Modules to the Basic SEQ====
 There are many modules that you might want to add to your SEQ after it's built.  For example:
-  * **[[http://www.midibox.org/dokuwiki/doku.php?id=tpd_pcb|TPD ("Track Position Display") Module]]** - Displays BPM and a LED matrix display to show the position of each track.  Also provides a rotary encoder for tempo adjustment, as well as four extra assignable buttons and LEDs.
+  * **[[:tpd_pcb|TPD ("Track Position Display") Module]]** - Displays BPM and a LED matrix display to show the position of each track.  Also provides a rotary encoder for tempo adjustment, as well as four extra assignable buttons and LEDs.
   * **[[http://www.midibox-shop.com/quadIIcMIDIR2.html|QUAD MIDI IIC Module]]** - adds four extra MIDI ports to your SEQ. More info [[http://www.ucapps.de/mbhp_iic_midi.html|here]].
   * **[[:aout_ng|AOUT_NG Module]]** - adds 8 channels of CV out for interfacing with modular equipment.
-...and many more.  These modules integrate pretty effortlessly into the SEQ.  The Quad MIDI IIC, for example, is plug-and-play.  The TPD module requires a few simple adjustments to your MBSEQ_HW.V4 file.  I believe the AOUT does as well, but I haven't built it yet.  Anyway, the MIDIbox framework is really incredible - these modules more or less "just work".
