Roland TR-626 Rhythm Composer

Roland TR-626 Image

The TR-626 is sort of an upgraded digital version of the classic TR-606 and TR-505 Rhythm Composers. This beat-box is still simple but has a few good points that come from its legendary ancestors - the TR-909 and TR-808. Its sounds are pretty drab, they are 12 bit low-quality samples of the most boring acoustic drum sounds around. Fortunately the sounds can be individually tuned and mixed and there are 8 individual outputs for the basic sounds as well as a stereo out. Its sequencer is very basic, coming with 48 preset patterns and 48 user patterns. But it has a simple matrix display similar to that on the TR-505, clearly displaying the current pattern in a graphical layout. The 626 also featured very good MIDI implementation for it's time. It has been used by Vangelis and Jimmy Edgar.

you have to modify the tr626 board to do the trick. but it's not difficult. first get a 7404 chip in an electronic store, then verify on the datasheet the pinout. the NOT logic port has only one in and one out. then connect the trig out of the tr626 to the input of the NOT logic gate, and the output to the trig in of the KORG stuff you want to synchronize.
don't forget to power the 7404!
i also added a switch to operate both positive/negative trig.
better results are in connecting it to a KORG SQ10, since a lonely trig signal is too simple for a decent control.
sorry for the grammar errors.

Why so much hatred for the 626? This thing is limited, but its [beep] ing awesome. Proper production skills can bring out the dancefloor in this peice of plastic....
and MIDI/CV gates? all in one??!?! why wouldnt they do this for everything?

I use mine as a trigger generator for my ms20+sq10. just added a 7404 ttl NOT port to the trigger out to achieve negative Korg logic.
now ms20+sq10 syncs perfectly to MIDI!!!!
sounds are usable too if you are an 80's enthusiast like me
