Back when I did all my beats on a korg ES-1 (which is still a tight machine, though I sold mine when I got low on cash) I picked up a 505. I had seen the 202 and 303 before but the feature set listed for the 505 blew me away. I had never used a sampler with onscreen waveediting, sustain loops or the timestretch-based pitch to keys feature you guys keep going on about.
When I picked it up I kept thinking "dude, this box looks like a toy box" and the construction of the unit was also fairly cheap, when compared to the MPC series or even the ES-1 (though the ES-1 does have cheap knobs you gotta worry about)
The features I liked best about it were the onscreen capabilities which I've matched on every MPC I've bought since (and my s5k) and the map to keys feature, which didn't sound any better than or worse than sped-up/slowed-down tuning as on the MPC/ES-1. The ES-1, as a matter of fact, does real time tuning MPC-style, while the 505 had no realtime tuning. (I don't remember for sure that it didn't have any tuning whatsoever, that seems like a crazy thing to leave out) Neither do MPCs, though.
The keys are laid out basically like an octave or two of a keyboard, and playing chords is very easy with this setup. You also have MANY banks of sounds as opposed to the MPC's 4, but you don't have multiple programs to access as with the MPC1k. You also only have like 10 "pads" instead of the 16 on the MPC. As people have mentioned already, they are not velocity or touch sensitive.
The auto-tempo matching feature, which I thought might replace Acid for me (occasionally I'll work with homebrewed loops and dump them to Acid for quick mixes) but it sucked. As Soundwave-rockin Decepticon said, a couple bpm off and the sounds are trash.
The effects were so-so on the Roland, since it's real cheap and it has a long list of effects. None of them are really good though. One of my main beefs was that you couldn't save effects settings ANYWHERE. Not in sequences, not in bank setups, nothing. This means you have to run them live when recording. You also can not sequence knob tweaks as you could on the electribe series, one of the major selling points for Korg.
Storage to SmartMedia cards, I liked. I was coming from the ES-1 like i say, and had been using SM cards for a while at that point. The 505 did something the ES-1 didn't, though: it uses the SM card as an extension of its physical memory. So while the card is in, it acts as more RAM. Cool. However, there's a major major catch: You CANNOT remove or insert a card while the 505 is powered up. This is **** stupid. It's also why there's a set of thumbscrews holding a faceplate on over the card slot.
The 505 has a decent hit-detection algorithm to assist you in slicing breaks, and will export a sliced break to a new bank, but it usually still requires a good bit of manual tweaking of hit locations.
The 505 also has an excellent system for copying and pasting samples from bank to bank. It was really innovative and I applaud Roland for it.
The 505 also only has a set of RCA jacks and an optical I/O. It cannot sample itself if I remember correctly, as the ES-1 and MPC1k can. I need my 1/4" jacks!
My last beef with the 505 was this: No transfer of samples made on the 505 to computer for backup or editing. On the ES-1 you can extract samples from an .es1 file using a free utility Korg created, and naming samples was a hassle since they had to be numbered 00.wav - 99.wav, but I took care of that with a little utility I wrote. Anyway, the 505 gives you no means of backing up individual samples to computer. Blah.
I did 2 or 3 tracks using the 505 mostly as a manual triggering device for samples I'd chopped on it (vocal hits, etc) to play alongside my ES-1. I also used it to compose a loop-based piece that came out of the 505 beautifully, a series of string loops I grabbed off an old record my uncle recognized when he happened by one day. It synced well with other gear, but it has no method for driving it with MIDI, not even a MIDI in if I remember correctly. This means you can't even trigger it from a better sequencer and must use it as your main clock source. Gross.
So sorry for the long blabber, but for the way I work, the 505 just won't do.
Hope this helps shed some light on things for everybody.
