ill be receiving my mpc 2500 tomorrow and it seems logical that at some point i will be getitng jj os xl, should i start with that? would that make the learning curve really steep? im also going along with the mpc 2500 book my mpc tutor, would i still be able to follow this with jjosxl? i want to get the absolute most out of this mpc, and i want to begin learning it all from day 1, what would you suggest?

I'd almost just say yes to everything you asked.

When I got my 1000 I used the Akai OS for about 2 days. I then tried the JJ Free OS, and also downloaded the OS1+OS2 and at the time OSXL. I ended buying XL the same night.

I figured even if it was a ton features I wouldn't use for a while it didn't make the MPC any harder to navigate or more confusing. Clearly there were more functions and screens but I find all the JJ OS's to follow the same basic logic of the Akai one while adding and fixing tons of things.

I'm almost positive Tutor's e-book added a JJ section and like I said even with the differences on the Akai and JJ screens it's like you just smile realizing the JJOS2XL does the same thing better.

It seems like the majority of 1000/2500 owners on this forum end up using JJ in the long run. So if you have the $129 or whatever it is these days I'd install now, play with it with save disabled and probably like I did buy it right away. The chart at the JJ site can really help to visualize which features would be most worth the price for you.

sweet, thank you so much for the reply man. yea i saw the
LFO PITCH in Q-Link REAL TIME
LFO FILTR in Q-Link REAL TIME
LFO LEVEL in Q-Link REAL TIME
LFO SPEED in Q-Link REAL TIME (OS128XL LFO RATE)
TEMPO in Q-Link REAL TIME
and was like aahhhhh man, i neeeed that. like i really want to master this beast, ive been researching them for the past 3 or 4 months and i just want to learn everything about it and jjosxl has so much stuff that if can integrate that into a concrete understanding of how this machine works, it really seems like thepossibilites are infinite

Dope. I figured if you already knew some stuff the chart would blow your head off. :nod:

Your approach is thorough man, you'll be flying in the first week or two I bet. The JJ forum here has some unbelievably clever users who post all kinds of cool stuff the XL feature set allows.

Another JJ convert. :mrgreen:

aaaah im so excited!! :fku: :fku: :fku: :fku: :fku:

lmao and yea this is tight man, i jus discovered this forum, like theres a whole community about this amazing heaven sent device? im gonna be on here all the time! :mrgreen: yea man you definitely got me on this jj ish, much appreciated!

yea ive been on and off of here without really recognizing the purpose of the site. i had another question if you dont mind, im also buying an akai mpk 88 and do you know if its possible for me to control parameters, fx, mixer within the 2500 with with the knobs and faders on the mpk?

This is a more recent addition to OS2XL. Looking at the chart you can see what functions you could control from an external controller. Definitely mutes and track selecting not sure if the MPC mixer faders are assignable. I have an MPD 32 with basically the same fader/knob arrangement of your MPK.

You'll need a DC plug and regular 5 pin MIDI cables for the MPK with the 2500. Again the 2500 USB is only for data transfer. Still it's cool you can have the MPK/2500 together with no computer. Even with a computer you'll need a DAW and a MIDI interface to have the MPC control VST's.

im really wanting to hook the mpk up to logic 9, control the sounds in there, and be able to play them into the sequence in the mpc, i cant really wrap my mind around it i guess, how would i set this up and what would i need?


Do you have an audio interface or do you just use your Mac's built in audio? You need at least 1 pair of MIDI Input and Output jacks. You can get a USB to MIDI cable for around $30

Here's an example - http://www.zzounds.com/item--EMUXMIDI1X1TAB

The scenario you're picturing would probably be the MPC as the MIDI master and Logic as the slave. One of the MPC's MIDI outs to the MIDI interface's in, and the MPC's MIDI in connected to the interface's MIDI out. Then you can switch it to Logic as the master if you ever want it that way.

Then you'd make as many MIDI tracks in the MPC as you have instruments loaded in Logic. You would tell Logic to receive the different MIDI tracks from the MPC using MIDI channels 1-16 and having A-D banks in each channel, basically you can send out 64 MIDI tracks if need be.

Of course you can have MPC programs with samples loaded at the same time as well. When properly synced over MIDI MMC/MTC (Machine Code/Time Clock) the MPC's transport controls will start and and stop Logic in sync with the MPC.

Here's the step by step - http://www.akaipro.com/synclogic

If you have no audio interface I suppose you'll have to record the MPC's stereo outs to the Mac's 1/8" audio input. You'll need a stereo pair 1/4" to 1/8" single jack cable for that.

You'd get better results with a separate interface and if an interface has enough inputs you can use the 2500 8 outputs and assign individual sounds to their own outputs. Not necessary if you don't mind solo/muting your track elements to get the separate audio parts into Logic. You could also bounce a rendered WAV file of your song inside the MPC and use USB to drag that to the Mac. In that scenario you'd also rely on a lot mutes/solos to get the different tracks out.

Yeah you sorta can assign CCs to control the mixer levels, but for some reason I stopped doing it. I think maybe it's a bit half assed, it only works if the mixer is onscreen, or maybe you need to assign the Volume CC of each unique channel.. something annoyed me about it anyway and I turned it off again. The buttons and pads are pretty controllable but loads of things are not. I'd rate it's midi controllability 4/10.

Innovine, I suggest you research a bit more.

Mixer works after you turn it ON and then it's just midi-channel 1-16 representing tracks 1-16 (takes Volume,Pan,Fx Send).

Here are some that I most frequently use.
cc => desc
---------------------------------------------
#01 => Modulation wheel
#02 or 74 => Filter Cutoff
#07 => Volume
#10 => Pan
#71 => Filter resonance
#91 => FX send

well, that was one of my suggestions :p doesnt work for me tho since that arrangement also changes my synth patch volumes up n down which isnt what i want (minus 2 pts for non arbitrary mapping). i'd improve the score if sample start and fx params could be adjusted via cc. one thing which would be neat but i havent tried, would be to go note for note through a recorded bunch of notes and use the qlink or a midi cc to set velocity and length per note. is that possible without a bunch of button pushing? sorry for the thread hijack :-)
