Feature:
Just about everything you could wish for in terms of options and sounds but for one annoying "feature" - read on...

Quality:
Good sturdy quality build with non-vol memory (beter than the 6xAA memory batteries needed with the D%-55- which used to let you down and loose memory just before you started performing.

Value:
Pretty naff in the UK but as I bought mine in the USA 9less than half price), good value for me

Desirability:
Great - apart from that incredibly stupid "feature" of starting the drum pattern in the middle when you re-start it.

Sound:
Pretty good sound - just like the DR-550 which I also own(2 of them in fact!) and have I used both models for over 10 years now for live gigs. The sound is good but there is one annoying "feature" that both machines have.

Ease of Use:
HERE is the annoying bit. Pity the designers of this family have never played with it live and used the drum machine for themselves in the real world of live music. When you hit the stop footswitch the sound stops when release of the switch (might sound daft but actually a it's a very good feature as it's easier to be more accurate when you release than when you step on to a footswith especially if you're singing and playing at the same time. BUT WHEN YOU HIT THE FOOTWITCH AGAIN TO RE-START, THE SILLY MACHINE STARTS AT THE POINT IN THD DRUM PATTERN WHERE YOU FINISHED!!! Why on earth doesn't it go back to the beginning of the patter to restart like real professional drum machines? Simple. It's 'coz the idiots who designed it never thought of it because they've never use it live themselves - otherwise this stupid annoying "feature" would never have hit the streets. They did it with the DR-550 and now with the DR-770. OH DO GET YOUR ACT TOGETHER YOU IDIOTS AT BOSS/ROLAND!!! More than happy to give you a spec that would be so easy to implement - if only you'd listen to a real musician who uses it in the real music world, not a lab.

Support:
Never had to use it for this machine but most unhelpful and very "jobsworth" orientated when I had a problem with a guitar synth pickup!

Overall:
I've used it for some time now and am not looking around for another. If I was, I'd probably avoid BOSS purely because of the stupid issue over starting the pattern in the middle. It really is annoying in a live environment and no other drum nachines I know of do this - they all do the sensible thing and restart at the beginning of the pattern. I know of many users of drum machines who hav avoided BOSS just because of this point.

Feature:
I see many complaints about the LCD. It doesn't bother me, but it is strange that they wouldn't throw that in. The programming is easy. The step recording of songs is very convenient.

Quality:
Well, I recently bought it and all I can do is keep my fingers crossed because it's not exactly a strong piece of equipment.

Value:
I found this to be money well spent. I expected less for $350 and got so much.

Desirability:
Great little box. Technically, it is really loaded. The little cheap box makes it a wolf in sheeps clothing. But it looks nice in my studio set up if that is an issue (?).

Sound:
Before using this little machine I was quite skeptical about the quality of sound reproduction of drum machines in general, but the DR 770 has changed my mind. With the exception of weak crash cymbal sounds, the drums are quite realistic. With a little tweaking of ambience and various sound parameters, it's like having a live drummer in the studio. The touch sensitive pads are not as dynamic in range as they could be, but they still make for excellent nuance. The sound is a lot better than I expected

Support:
Dunno.

Overall:
I am really happy with this. I'll be over it when I hire a full-time live in drummer, or win the lottery. Inthe mean-time, this has proved to be the missing link in my total music making capabilities.

I think this drum machine is great. I feel like a putz because I almost sold it to get a ZOOM RhythmTrak because it had the option to hold down a button and press one of the kicks/snares/etc. and have it repeat (Good for double-bassing). My friend had the RT and I saw his had this and I thought mine didn't but, ha, little to my lack of knowledge it does :) Anyway, good things: So many features, so much space, good for chillin' alone w/ headphones or jamming w/ the band. Bad things: Needs backlit display, fonts are a little small, sensitivity on pads not as good as it should be for $500 (to get a weaker hit on any pad you have to barely touch it and even sometimes if you're too quick it won't work), and pads are sometimes non-responsive. For realtime jamming it kind of s@@ks to need a bass/snare/tom/etc. right in the right place for a fill and it doesn't catch it when you do it. Overall this product is worth it. The complaints I have are easily resolved by getting a real drummer with a real drum kit. If you're looking for a machine to do a human's job tempoarily, this is your tool!

Ok, I'll have to admit it took me a little while to grasp, but then again I'm not a drummer... so maybe I have an excuse. ???

Anyway, there are so many features that you can tweak ( pitch is very important ) and it starts to get addicting. Spend some time with the Boss Dr770 and you'll find out that you really can personalize your own drum sound and create professional beats and rythyms.

It's pretty compact and portable too if you're a "book-bag person". Although, I'm looking into somekind of battery/power-pack for it. Until then, I'll still be scouting out places wear I can plug in.

best drum machine for the money, and sounds even better that machines costing much more. Its very easy to create songs with the step record feature. There are 256 sounds that can be tuned and tweaked.You will not be dissapointed with this machine. I have at least 5 drum machines and this is the only one I use. I may buy one more, to have an even fatter sound.

The Dr770 is one of the best it never lets me down. THis drum machine has some amazing pre recorded songs and the custom drum machine cappabilities are of the hook this is the great I'd reccomend it to anyone thats serious about recording. This thing is awsome the drums and sounds are so realistic!!

This little machine is extremely versatile and has the best drums sounds of any drum machine for a home studio in it's price range. When you listen to a song with drums from the BOSS DR-770 in the mix, they sound tremendous!! Worht every penny!!!

Im not, by far experienced with drum machines or other brands. But doing a lot of research, Ive found this one to be the most high rated DM for the price range. I like the editing features and when you cant get a good flow to a beat, the 400 preset drum patterns are good fill-ins. It does @@@@ it dont have a back lite LCD, but the quality of the drum sounds and the features of the machine its self, to me any way, was worth the loss.

i bought this thing a year ago w/ no previous beatmaking or producing experience. im very happy w/ what ive been able to do w/ the dr 770. i like the range u have in tweaking w/ the individual notes. id like a better selection of bass sounds but other than that, im cool w/ this thing.

Top of the line, isn't it. I got all I want from this little guy. All custom setups for each pad is so cool. I can adjust anything I can think of. Variety of sounds and lots of space for keeping my own pattern.
