 ======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.

+  * Either a CORE_STM32F4 (with MIDI I/O board) or a CORE_LPC17 PCB;
   * Wilba's Frontpanel PCB;

-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.

 ===MIDIbox-shop.com===
-[[http://midibox-shop.com|MIDIbox-Shop.com]] is run by SmashTV (Tim), a longtime member of the MIDIbox community.  PCBs for many MIDIbox projects are available there.  Kits are also available for some projects, and he offers some commonly used parts for sale as well (like MIDI jacks, IDC connectors, LEDs, Encoders, etc.).  The prices are extremely reasonable.

-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.

 ===Wilba Frontpanel Parts Bulk Order===
 SmashTV also runs a bulk order for the parts required for Wilba's Frontpanel.  I'm not entirely sure how this works, since I sourced my own parts.  But I hear the bulk order is still ongoing.  Check [[:wilba_mb_seq_pcb_bulk_order|this page]] for more information.  I think you have to contact SmashTV on the forums to be added to the bulk order list.
+===LCDs===
+You need two [[http://midibox.org/dokuwiki/offline/hd44780_compatible.html|HD44780 Compatible]] 40x2 LCDs.  You can find cheap LCDs on ebay or from [[http://www.buydisplay.com|BuyDisplay.com]].  Or you can get all fancy and use OLEDs or VFDs if you want.  The SEQ is a great device - it deserves some decent displays...  But you can always add them later.  Since they're just connected by IDC cables, it's very easy to switch displays.  I used [[http://noritake-vfd.com/cu40025-uw6j.aspx|Noritake CU40025-UW6J VFDs]].
+===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.  But if you want to cut your build costs, foregoing a case will really save you a lot of money.
+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.
 ===Build Instructions===
 Build Instructions for the Core modules can be found on uCapps.de:
-   * [[http://www.ucapps.de/mbhp_core_stm32f4.html|CORE_STM32F4]] and
+   * [[http://www.ucapps.de/mbhp_core_stm32f4.html|CORE_STM32F4]]
-   * [[http://www.ucapps.de/mbhp_core_lpc17.html|CORE_LPC17]].
+   * [[http://www.ucapps.de/mbhp_core_lpc17.html|CORE_LPC17]]
+There is also a lot of useful information in the SEQ User manual's [[http://www.ucapps.de/midibox_seq_manual_hw.html|Hardware Options page]].
 Build instructions for the Wilba Frontpanel can be found [[:wilba_mb_seq_construction_guide|here]].

 If you're using the CORE_LPC17, you'll also have to make a SD card connector, as described [[http://www.ucapps.de/mbhp_sdcard.html|here]].  The STM32F4 Core has a built-in SD Card slot.
+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:
+  * **[[: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.  Just plug them into the right IDC connector on your Core.  The Quad MIDI IIC, for example, is 100% 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".
