I GOT a drummer!

By Tenor1

from Egg Harbor Twp. NJ

Comments about Boss DR-670 Dr. Rhythm Drum Machine:

When they first put this on the shelf I bought it. I have yet to regret my purchase. It paid for itself the first show I did with it. I use it for everything you would normally use a drummer for. I do recordings with it, practice with it and compose with it. Lol, it always on time and it even allows me to put my bass down and work the crowd with my mic at some of the gigs I do.

Need a drummer?

By Misconduct2K

from San Diego, CA

Comments about Boss DR-670 Dr. Rhythm Drum Machine:

I looked at a lot of drum machines before purchasing this one. Overall, the feel of the pads combined with the quality of the samples made this machine to good to pass up. The included patterns are a great place to start, but the real potential of this machine is revealed when you begin to record your own patterns and songs. Invest in the footswitch - it will make your life a lot easier! Tons of sounds and kits - make your own kit if you don't like the pre-programmed ones. Anything from natural to hip-hop, studio to world, this machine has it all. Velocity sensitive pads help add realism to the mix, and you can control individual aspects of each sound like the amount of reverb or sustain - even if you hit the drum head in the center or on the side! Like all drum machines, the cymbals are a little weak and unrealistic...but for those of you without access to a drummer, this is the next best thing.

Easy To Use

By DSDub

from Chula Vista, CA

Comments about Boss DR-670 Dr. Rhythm Drum Machine:

This is a very simple drum machine compared with some of the other units out there in this price range. Pick your kit, pick your pattern, and off you go. Recording your own patterns and songs is a snap. There are some advanced functions if you want to dive deep and edit individual sounds, but I haven't had the need to do that yet. The presets sound nice, but you'll want to record your own patterns to give them a "human" feel. The LCD screen is a nice size as well. Pads have a nice feel to them and are velocity sensitive too. Great buy!

Does the job well

By Val

from Vancouver, WA

Comments about Boss DR-670 Dr. Rhythm Drum Machine:

If you are looking for an affordable drum machine box that you can plug into a PA system or in the input channel of your recorder (as opposed to drum machine software that runs on your computer), this is it. I don't feel disappointed with the sound quality - it's not jaw dropping, but it may make you raise an eyebrow. The drum sounds have a little bit of reverb and they are all stereo which creates realistic spatial positioning. If you hit the low tom, you hear sound coming from the right; if hit a high tom, you hear sound coming from the left, etc. Pads are force sensitive, though a bit finicky in that regard (or perhaps I am not used to them yet). Supports rolls and flams with adjustable parameters. The default sound falloff may be too sharp but this can be modified using a custom envelope (where you set attack and decay time). Up to 20 voices can be played simultaneously, with some instruments possibly using more than one. All percussion instruments can be configured with more bass or more treble by specifying how close to the center of the instrument a drum stick strikes (on the edge more treble, toward center more bass �ۡ���� called �ۡ��̏nuance�ۡ�ݕ�_). Also note that there are slightly more expensive drum machines that support timbral changes which modify the sound of instruments every time they are struck �ۡ���� in case you are looking for even more realism. Lots of instruments are available - besides drums you have several bass guitar sounds that you can save within a pattern along with drums. Bass sounds passable and there is a wide enough choice of muted bass, slap bass, pick bass, fingered, acoustic, synth, etc. The drum sounds are varied enough to play anything, especially if you plug the outputs of this unit into effect boxes like distortion, phaser, delay etc. There are also a few effect instruments available such as �ۡ��̏tape rewind�ۡ�ݕ�_ or �ۡ��̏gate reverb�ۡ�ݕ�_. If you never used a drum machine this one may be difficult to use at first, but be sure to disregard any reviews where people say it�ۡ���s too difficult to use and call it a lemon. The important thing to understand is that you have to follow all manual instructions to the letter, even the tiny print. If you don�ۡ���t pay attention and skip a step (happened to me more than once when I started using it) you will get frustrated quickly. As soon as you realize this, you will start enjoying using this machine. There are certain patterns to the user interface that are actually very intuitive, and after learning a little bit you will soon be able to figure stuff out without reading the manual. My only complaint is the small screen that allows display of only one instrument at the same time (you see dots for only kick or only snare etc.) but that�ۡ���s part of why this unit is affordable. However, midi inputs/outputs make it possible to edit patterns on your computer and then upload them into the unit for performing. Last thing to mention �ۡ���� the manual repeatedly says this unit can be easily damaged by vibrations, so be sure to treat it like a newborn baby. If you take it on the road be sure to use lots of packing material, and don�ۡ���t even plan on dropping it.
