Q-Link real time and external keyboard issue JJOS

Hello,

I couldn't find any info on this so I hope somebody can help.

I'm having trouble trying to play my MPC using a MIDI controller keyboard and vary the parameters in real time using the Q-Link controls (i.e. use it like an old Akai sampler). I'm using an INST program and if I play the notes from the MPC pads it works fine but if I play the notes using my MIDI keyboard the parameters reset with each note. It does this for all the parameters (e.g. filter, LFO speed, LFO level, pitch). The reason I want to get this sorted is because for melodic parts I find it much easier to use a keyboard than the pads and I wan't to tweak the sound with sliders etc while I play. I haven't tried using MIDI cc from the keyboard instead of the MPC's Q-Link controls. Gonna just try that now.

I am using an MPC2500XL with JJOS XL 3.2.1 and an Edirol PCR-M30 MIDI controller keyboard. I'm pretty certain there's nothing to change on the keyboard - it's a basic controller. I find the JJOS manual very difficult to read.

Hope someone can help. Thanks.

...using cc MIDI messages from the keyboard made no difference.

I can send the cc numbers 2 and 71 from the keyboard to control the filter cutoff and resonance for what I play on the pads but it has no effect if I play using the keyboard! Strangely, if I play the pads and change the filter using cc 2 and 71 from a slider on the controller keyboard it works, if I then play the notes using the keyboard the sound is unaffected by the filter settings (they reset) then if I go back to the pads the filter settings are still there as determined previously by the slider on the keyboard.

Modwheel and pitch-bend (using the keyboards dedicated modwheel and pitchbender) work fine for notes played from the keys but still not the CC2 and CC71 for the filter for notes played from the keys.

OK, hold on. Maybe I read you wrong but could you pass correct number of your OS?
Do you have XLCD screen?

Hi,

When I switch it on it says JJ OS-XL Version 3.2.1.

All I know is the screen came with it new. Its 240 x 64 dot graphic LCD w / back light.

Its an MPC2500 Special Edition.

Hope that helps. Thanks.

OK seems you got free OS128 (for big LCD). This will not work at the moment on this OS from what I know. This is simple operation but not available. Only OSXL 3.45 for 2500 will do it.

Excellent! Thanks. I paid before so I already have a password so no extra cost!

Bad news.

I installed the OS XL 3.45 but it didn't fix the problem. Still can't play from an external keyboard without each new note-on message resetting the values assigned/set by the Q-Link controls.

Have you recorded those q-link events into the sequence? I'm not sure what are you doing exactly.

I wanted to see if I could play the sounds of the MPC from a MIDI keyboard and shape the sound on the fly quickly and easily by using the Q-link sliders and knobs rather than having to change screens and use the cursor and data wheel. Basically, just to use the MPC a bit like a synth module before doing any sequencing.

This wasn't working so I started investigating. After each MIDI note off (or with each fresh MIDI note on, not sure which) recieved from the MIDI IN port the Q-Link controller settings of parameters e.g. LPF are overridden by the values set on the FILTER screen, even with the AFTER button illuminated.

I found out that I can use the Q-link sliders and knobs in this way if I play from the pads or record a sequence first but not if I play notes live using a MIDI keyboard. I did try recording the slider motions on a sequence with MIDI notes in, no problem with that.

I guess I can live without the functionality but wanted to know if I was missing something or if it is true that the MPC cannot do this. I just found it surprising because it seems like a pretty basic function. I also wonder if its JJOS or if the AKAI OS would have done it.

I don't know dude, ain't got MP with me now for check, but as I read you right:

1.you press a key on keyboard, move a slider on MPC (ie LPF) > you can hear filter sweep
2.you leave q-link in a position (100) other than in Program (50)
3.you press a key on keyb > value of LPF is reseted to 50

^^this?

Yep. Thats right.

On OS2XL you got MIDI monitor (your free 128 OS does not support that),
check does it send anything else than notes.

Hi,

Yes, the keyboard is sending correct note, velocity and cc changes. Nothing else.

I've checked the settings in 'MIDI sync' and all looks OK.

I am familiar with the MIDI monitor because it was there on my previous version; OS-XL 3.21, which wasn't free, that's why I didn't need to buy a password this time around. The free one was 3.12 I think.
