- | 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. | + | {{youtube> |

+ | 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 most exotic component on this board is the red/green double color dot matrix module. As the LEDs are controlled via a matrix approach, it does not really matter whether you choose common cathode or common anode modules - both will work, you'll just have to specify that in the config file. I bought mine on ebay, and they are common anode types (although they were sold to me as common cathode types!). Make sure that the pinout follows this {{: | The most exotic component on this board is the red/green double color dot matrix module.
