Dr. Rhythm DR-770

Hot and in the pocket?

I owned the 770 around 2002 and it's been since discontinued. Called "the most advanced compact rhythm machine ever" when it came out, this drum box was packed with features, patterns and samples. Goodness, it held 10,000 patterns! You could apply effects, the buttons had extreme sensitivity, you could trigger patterns on the fly right off the front panel, it had tons of samples — 52 kick drums alone! The first sample based drum machine I owned, the Roland 707 had 2, and a dozen or so samples in total!

Ok, ok, I'm bridging decades with the two machines, but am I the only gear geek who thinks Boss/Roland was referencing its drum machine heritage by naming the 770 so similarly to the vintage 707? I don't think so. When they introduced the 770, they were most definitely making a point that the new unit was a milestone model, like the 707 was.

Back when it was introduced in the 80s the 707 was the first affordable sample based machine with professional features like individual outs, memory cards and high quality sample resolution (12 bit, high for then, in any case). It had groove-box style, front panel, bar/measure based visual LED programming. It even had a hands-on front panel mixer with a dedicated slider per drum sound! It was easy to get in there and get musical. Who knew how limited it was back in the 80s?

Years later, the 770 obviously blows the old piece away in terms of what it could do, if you could only figure out how: pattern memory, samples, dynamics, effects, you name it. The problem was I couldn't figure out how without sticking my head constantly in the manual. What happened with the 770 can be explained using everyday math. Observe the following formula:

A lot of user friendliness and musicality was lost along the long path that led from the 707 to the 770, and drum machines have become charming retro devices because of this trend in overly complex user interfaces. Computer based instruments make life at least somewhat easier with their infinite recall and generally more complete visual representations of parameters. I doubt most owners of the 770 learn how to use even to 10% of what it was capable of.

A bit of added drama surfaced online around this machine too. Complaints bubbled up about it getting extremely hot, possibly dangerously so, and possibly to the point of damaging the unit, burning the D.J. or even starting a fire. Probably unfounded, but enough to put a scare in me. And for the cost, close to $400, as I recall, it soon seemed like overkill. I sampled my favorite patterns and use those sounds in Ableton Live to this day.

But hey:

• if you want an over-the-top traditional style drum machine
  
• if you're willing to climb a steep learning curve
• if you have an ebay account

Log in and get one of these for about $159. But make sure it comes with a manual.

Elegant, Modern Slab

Nobody is raving about it, it is not coveted or collected, yet it has been in production for like 20 years. This is possibly the best selling drum machine ever, if only because of its super-long market life. I had it once, got rid of it and bought another one a few years later.

What's the secret? Well, the thing just plain works. It's got a 200+ samples, it uses dynamic articulation to change up samples as you play/program louder or softer, making for an unusually realistic sound to the ear, in my opinion. You have all your techno sounds, all big rock sounds, percussion sounds, basically every drum sound you'd need.

The programming is easy too, and it makes for a really good playback module. With midi you get an enormous amount of sounds mapped across the range of midi key numbers.

It also looks very simple and streamlined, it's design an elegant, simple, unobtrusive modern slab.

At least that's my theory why it's still selling. Hey I just may get another one tomorrow. I'm having some serious nostalgia for the thing right now.
