DR Link

One of the very few analogue machines I own and have messed with. The Boss DR-110 was the last analogue Drumbox built by Roland. Fun fact: Boss, Roland and Edirol are actually the same company. In its vanilla state this one must be quite a disappointment for those used to the power of the better known Roland machines. It has its charm, but certainly lacks the punch and versatility of an 909 or 808.
Boss DR-LinkThen again, it's a lot smaller, comes for waaaaay cheaper and has a few nifty tricks up its own sleeve. Gorgeous claps, for a start. I don't remember what I paid for mine, but it must have been in the 10-30 Euro range most of my instruments were in.
It is very easy to program and the preset beats, despite all their cheesiness, can be unexpectedly funky if played at the right speed. It can run on batteries, which also retain its memory, but I've stopped bothering with them years ago and now, I mostly use presets or program beats on the fly. In the rather unlikely event of coming up with a rythm that I really need to keep, I just take a photo of the display, the grid structure is perfect for this.

With analogue gear, you usually don't achieve very much with the common 'poke-around-on-the-circuit-board-and-see-what-happens'- approach. You can get nice effects, but most of the time, you end up with mostly annoying, rarely controllable noises or fried parts. So this had to be done with a bit more of a plan. Luckily, the DR110 has a pcb that's not too complex, the schematics float freely around the internet and there's plenty of websites telling you which resistors to replace with which pots are.

I came up with 2 or 3 mods of my own, just to discover later on, that they have also been documented elsewhere, meh, whatever...

With the mods, the DR-110 becomes such an amazing machine. The Kick is waaay more powerful now. It's not an 808 bass all the way, but close enough for me. It sounds very warm and properly scrambles your guts when played over a decent PA. The snare can now be tuned and the snap level can be adjusted, so I can also use it as a tom of sorts. The cymbals are all created with the same noise source, which means that the pitch change is global for all cymbals, which is actually less a problem than I expected when I built it. The music of my 2006 song "Lebende" is made entirely with the DR Link sent through some distorsion. In 2012, I made a weird karaoke video for it:




  • Kick: added 808-ish punch, pots for tune and decay
  • Snare: tune, decay and snap impact pots
  • All cymbals: tune pot
  • Hihat: filter, open hihat decay pots
  • Ride: pots for filter and decay
  • Clap: pitch and decay pots
  • Inverted screen, green screen backlight
  • Sync input with switchable clock dividers





How did you do the backlight? Very cool!
