Noob question - jjos-xl / mpc2500

Hi guys,

Forgive this probably stupid question, but your help is much appreciated.
I'm attempting to learn the MPC 2500 using JJOS-XL and battling my way through various different manuals... the translated XL manual is a nightmare!

Anyways...

I've got an Alpha Juno as my master keyboard plugged into midi in 1 and the MPC is receiving midi no problem. If I create a drum track program with some samples and press play it plays back fine. If I hit keys on the midi keyboard whilst it's playing it interrupts and cuts out bits of the audio (this happens whether the track is currently on-screen/active or not). Is there a way to disable midi input for these tracks so that the audio doesn't get interrupted?

The program is set to poly by the way... also tried it in mono.
Multi timbre: off, Active track receive channel: 7, Soft thru: as track, Sequence change by program change: off.

Also if I create an audio track and press play (whilst the audio track is on-screen), pressing keys does nothing. If change to another track and press play, then hit keys on the keyboard it cuts out the audio track until the end of the bar and then it starts playing again.

I'm sure this is something simple. I am working my way through the manual but this basic thing is driving me nuts.

Any help much appreciated!

When you play the juno do you hear both samples being triggered and the keyboard?
It sounds as if you have a program set in your midi track.Turn program off.

Also it's worth checking out the Voice Monitor while your sequence plays.



MIDI doesn't eat up your polyphony, but your samples loaded into mpc do.

Hi guys,

I've only got 2 tracks here (1 drum track and 1 audio) so polyphony isn't an issue.

* If the drum track is on-screen, when I press c0 for example on the keyboard it triggers the kick sample. whilst playing, when i press some keys it interrupts not only bits of the drum samples, but the 2-bar audio track which is on sequencer channel 2 as well (until the end of the 2 bar loop, when it starts again).

* If the audio track is on-screen, it doesn't seem to cut anything out when I press some keys (this is fine...).

* If I create a third track (midi) and have this on-screen, it still cuts out bits of the drum track and the entire audio track (this is the case if i use a different program for it, or no program assigned at all).

If I press the pads I do not have this issue.

This is driving me nuts. :/
Once again, any help appreciated!

right, i just did some more troubleshooting by trying a different master keyboard. i used my little novation 25-key midi controller and the issue doesn't occur when i use that. it seems to be related to my alpha juno and the mpc behaving oddly when i hit keys on it.

my juno seems to be sending cc123 "all note off" messges whenever a key is released, which is messing up the mpc by interrupting the drum/audio/midi tracks. looks like it's a feature/bug in old roland synths.

there isn't a midi filter for jjos by any chance is there?
or can cc123 be re-mapped by the mpc into another (less intrusive) cc number?

anyone know if this is possible?

No, there is no midi remapping in JJos beyond remapping channels for the "AS TRACK" thruput.. Not sure if even the 4000 has that capability and as far as midi goes that's the best MPC they ever made.

If you absolutely have to use that (notorious) keyboard as your master the only non-computer solution I can offer is Midi Solutions products.

much appreciated. this is what i thought would be the case.
i'll probably get myself one of these in the new year as i wanted one anyway..

i think that will work too? the bit near the bottom says "The MIDIpal can also store 4 custom MIDI transform setups, each of them made of up to 4 filtering/remapping rules." The picture of the filtering options on that page looks as though it does what I need?

Have you tried assigning cc 123 to the q link or cc to pad and recording the cc to nullify the cc in the active tracks?Edit. Or selecting control change 123 all tracks in erase?

Yup, looks like it has the basic function. Can't vouch for the performance of any Mutable box as I only have experience with M.S. I like the way M.S. publishes all their latency specs and such but at least that has a decent feature list I suppose...

Yep, assigning to a Q-Link appears to have fixed it. Good call!

Glad to hear. I knew you do not have to invest in external gear to filter when you have
the control in your operating system.Peace TYPO
