Every week, a quick writeup of what we were up to.
Wesen:
- check out this machinedrum disassembly
- midi-ctrl 0017 built on linux: instructions
- added text and graphics graphs for the midi-ctrl documentation: modules, GUI, MIDI, Encoder, GUI, Page, Sketch, MidiUart, Sysex, IO. More to come soon!
- working on a DMX side-project
Ruin:
- biosc cover is taking shape!
see you next week!

Every week, a quick writeup of what we were up to.
Wesen:
- lots of small electronics building :)
- gave a two-day workshop about electronics and arduino in karlsruhe at the design school hfg
- lots of html/css/photoshop...
Ruin:
- finished documentation and starting first batch of bioscs
- modded the trigger outputs for kpr-77 (check the blog)
see you next week!
KPR-77 Ultimate Mods Series: Trigger Outs05.07.2010 09:34:56
In this modification of the KPR-77 'ultimate' mod series we will be discussing how to modify the unit to have trigger outputs. Trigger outputs can be interfaced with modular gear or other instruments that have trigger inputs, such as analog drum units.
Extracting the trigger outputs is quite easy on the KPR-77. Locate the PCB labeled KLM-448 and unscrew the four screws holding the board in place. Detach the two ribbon cables and flip the board over. The pin on the top ribbon cable closest to the center of the machine is ground. Depending on what kind of jacks you use, you may need this. If your devices use banana jacks, you can omit ground but you will need to connect ground by some other means (like running an audio cable to the modular as well). If the device you want to trigger has 1/8” or 1/4” you will need to connect ground. In order, from ground over the outputs are (drum names and abbreviation used in the diagram): Clap (CLP), Closed Hi-hat (CH), High Tom (HT), Low Tom (LT), Open Hi-hat (OH), Cymbal (CY), Snare Drum (SD), and Bass Drum (BD). On the KPR-77 the Cymbal and Clap share the same trigger buttons but are swapped when creating a pattern. This is why you can only have one outputting during a pattern. When I installed the trigger outs on my unit I fixed a small breakout box to the left side of the KPR-77 and mounted the outputs in the box. There may be enough room within the KPR-77 to mount the trigger outputs on the unit itself-- this is up to you. It should be noted that these triggers are positive going pulses, so if your unit needs negative going triggers, this modification won't work. You can extract negative going triggers from the IC's on the KLM-448 board, but since I don't have a use for these I haven't written about them.
Now you can enjoy the KPR-77 with your other gear without having to use just the two tom outputs.
Keep checking back for more KPR-77 Modifications!
