Hi guys,

thinking about upgrading my MPC to JJOS2XL and recognised that when purchasing a key, you also seem to get access to JJOS3.

The JJ comparison chart shows a load of different features… does someone possibly have experiences to share, where JJOS3 is better than OS2XL? How’s the performance? What are the main workflow differences between these two? What else to know?

Thanks!

There's a comparison chart on the JJOS website http://www7a.biglobe.ne.jp/~mpc1000/chart_n.htm

In OS3, you get lazy chop, and a few nice workflow improvements, but you lose some (important for me) features for sound design like LFO, aftertouch, etc.

Also projects are not cross compatible, so I suggest you save OS3 projects in a separate folders (don't be like me). You can then swap back & forth between OSs. Although I wouldn't recommend doing it on a daily basis not to damage the flash memory.

Jjos3 is like a breath of fresh air for your mpc.

Recently pulled the trigger on an old MPC1000 and purchased JJOS XL for it. After spending some time in XL I went ahead and tried OS3. All I can say is wow, if I'm not using any external MIDI stuff or Aftertouch, the Lazy Chop feature and real time stretch make it hard to go back to XL. Most of what I found online is that people prefer XL, not sure if that's old info or still current?

I'm new to this so maybe I'm off here or other workarounds in XL but for how quickly you can chop a long sample and get it onto the pads in OS3 is pretty nice. I found the Auto chop in XL still has to be manually edited so not sure if I'm missing Auto chop in XL. Curious what you guys who've spent more time in both OS3 and XL think.

Also, want to say love & thank JJOS's work but damn that manual is hard to digest, lol

A couple of things I like on XL that didn't make it to OS3 are the 5 track view option on the main screen, and being able to send MIDI cc from the sliders. Other than that think OS3 has the better work flow.

No, I'm referring to this option on the main screen (SHIFT+VIEW).

Sometime it's very convenient to see all your sequence tracks plus level, pan, output assignment, FX levels all on one screen. I'm always using the individual outs so I like having this view option. Just a personal thing, might not be that important to other peoples workflows.

In a nutshell.. jjos3 has a better unified program editor with non destructive slices, a real time time stretcher and more features in the audio track mode plus some changes in trim mode. os2xl has pad scenes, better xox editor and much better piano roll editor.

I really like the track edit function of os3 which isnt in 2xl. and the live retrigger mode is a lot of fun, albeit not recordable sadly.

Its a shame a hybrid of the two would be perfect. i miss the tails when chopping in 03. And the being unable to edit in grid mode is a real pain.

i started with jjos after 03 was released unlike a lot of people who were using 2xl so i went straight in to 3, thinkng the latest would be the best. im still torn between the 2 although use 3 by far the most. i wish hed mix the best/most requested features from 2 into 3, if space is an issue, ditch things like the realtime timestretch which is nothing more than a gimmick afaict, and nothing ableton etc cant do far more easily and better quality. dunno maybe im missing its use.

theres some really odd design decisions as well like eg the arpeggiator which only works live, not on recorded notes. i thought great, ill record some chords then play with the arpeggiator/send it to midi devices, but it doesnt work like that.

regardless, either are by far the best os for hardware samplers ive ever used and mainly bug/glitch free and rock solid.

I'd pay good money to see a JJOS combining the best of both worlds (JJ if you read this). Always been torn between the two, but came to the conclusion that if your are mainly sample based without external gear, 3 is the best. And if you deal with other instruments through MIDI, 2XL is the way to go.

I bought xl a couple years ago. Then I switched to os3. At the end till today I am using xl.
Most of the time I use Ableton samples and arrange them in xl.
A hybrid would be great.
