For the Main PCB, NOT the 3 x TM1638 PCBs seen in the video.
The Main PCB Has the ATmega328 (Arduino compatible) IC and the Flash Memory.



Detailed information

  • 16 Drum Tracks (note on/off, 3 velocity values).
  • 1 Accent Track. But each step can be set: Accent Track, Min or Max.
  • 8 Note Tracks (note number, 3 velocity values). Steps have the option of Slide and Note Off.
  • 30 Songs.
  • 64 Patterns per Song.
  • 16 Steps on screen, plus ABCD variations for a total of 64 steps.
  • Double Steps (in between steps option when editing the steps).
  • MIDI Processor Per Track. EG: Fade In, Fade Out, Fade InOut, Fade OutInt, Random Velocity and more.
  • Simple Hardware design, based on the easy to find TM1638 IC based boards. Just search on eBay and you should be able to find several options. We used 3 boards that has 8 x buttons, 8 x LEDs and 8 x LED_Segments. Such as THIS one. The board uses a single ATmega328 running at 3.3V, one FLASH chip for storage and connections for the TM1638 boards.

About the Beat707 Mikro PCB: the only thing missing are the interface buttons which you will need to provide and attach to the PCB Main Headers.See the video on our front-page for details. The Headers has all the 11 buttons pins and ground pin ready for connection directly to any push button you may want to use. No keyboard matrix used, no extra components required as we use internal pull-up resistors for each button.
