Feature:
great sequencing, menus are easy once you read the book, comes with an ac adapter.. some people might take issue with the outs, all are 1/4 inchers and midi, but there's headphones, aux, left out right out etc, so there are a bunch.

Quality:
the build of this thing is easily described: Solid. Solid plastic, sturdy pads, wheel feels durable, no flex. This thing doesnt feel at all hollow, it feels like thick plastic with a solid metal core.

Value:
I think this is well worth the price most are selling it for, if it was msrp.. well still worth it, but harder to pull the trigger on it.

Desirability:
this thing looks, sounds and feels great.

Sound:
The sounds are excellent quality. The sound from the out's is powerful and clear, some cheesy drums included but its just a matter of taste i guess. The bass feature is a bonus so im not gonna be too judgemental on that one but it gives you 3 ocataves(i think)of basses, some are pretty cool, some are blah.

Ease of Use:
even with the limited LCD the machine is easy to use. The documentation is very clearly written. The limited display and interface only becomes an issue when step editing certain events in high step patterns.. no big deal, takes a little patience. Buttons/wheel feel great.

Support:
Dont know anything about the support.

Overall:
I cant speak for others but this machine does what i want it to do and it does it very well, it's predecessor was widely sold/used from 1989 till today, this one might just do the same, alesis-sr20 in 2037?

Feature:

Quality:

Ease of Use:

Overall:
