 ====== MIDIbox SEQ Track Position Display module ======
-Based on an original idea by Hawkeye who implemented an 8x8 LED matrix display to show the current track position in his MB SEQ, I designed the TPD module. It does not only provide an enlarged (and duo-color) LED matrix, but also a BPM display and dedicated tempo/BPM encoder, a step display, and four freely assignable buttons with adjacent duo-LEDs for status feedback.

+===== Introduction =====
+Based on an original idea by Hawkeye who implemented an 8x8 LED matrix display to show the current track position in his MB SEQ, I designed the TPD module. It does not only provide an enlarged (and duo-color) LED matrix, but also a BPM display and dedicated tempo/BPM encoder, a step display, and four freely assignable buttons with adjacent duo-LEDs for status feedback.
 In my MIDIbox SEQv4, the TPD is sitting below Wilba's control surface panel, and to the left of my [[16x4blm_pcb|16x4 Button LED Matrix board]]. This makes for a nice and clean user interface and can be easily built into a 19" / 17" wide case.

-If you are interested in building this, send a personal message (PM) to user //ilmenator// over at the [[http://midibox.org/forums/|MIDIbox forum]] (you have to register to be able to send PM). As of April 2015, I have PCBs available for 9€ each, as well as a small number of kits for those having difficulties sourcing the parts themselves. Kit price for all you need to build this, i.e. PCB including every part on the BOM below, is 45€.

+===== Euro TPD format =====
+Since November 2016, there is also a Euro Rack compatible PCB available that has slightly modified dimensions and component placement. Alas, the mounting holes have also been moved around a bit. This was necessary to make the TPD compatible with the Doepfer Euro Rack series - a little taller and a little less wide.

+The Euro TPD uses the same components and footprints as the "standard" version, so just follow the BOM below.

 A config file suitable for use with the TPD module chained after my [[http://www.midibox.org/dokuwiki/doku.php?id=16x4blm_pcb|BLM module]] can be found {{:home:users:ilmenator:tpd_mbseq_hw.zip|here}}. An example configuration (TPD directly connected to J2 of Wilba's Frontpanel PCB) can be found in the [[http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fsequencers%2Fmidibox_seq_v4%2Fhwcfg%2Fwilba_tpd%2FMBSEQ_HW.V4|repository]].
+Some users have reported problems when the TPD is not the last module in the DIN/DOUT chain, presumably because the are 9 DOUTs on this module, but just one DIN, which in turn leads to an unbalanced serial output, see [[http://midibox.org/forums/topic/19801-tpd-blm-16x4/|this post]]. It seems best to simply put the TPD at the end of the serial chain.
