So im loving using animoog with the MPC as it responds to the note pressure (in addition to velocity) of the pads awesomely.

however i also like to change the midi note out of each pad so that all pads are in a certain scale.

but when i change the midi note of a pad, it does not send pressure info for the new note.. and if i return it to the default midi note it sends pressure again.

is this a bug with the OS or am i missing something?

What is note pressure??
you mean velocity, or do you mean after touch

he's probably talking about Poly Pressure
prepare for a really crappy metaphor

if you are a jetski, you're moving along. when you look back, you see that you've created wake.

however, if the hand of gawd picked up the jetski and put it down 20 feet away, if you looked back, you would see no wake. the wake would remain in the place where you originally created it.

Haha nice metaphor.. I also pictured a jet ski when I was thinking about this problem, it's the obvious go to :lol:

Yep poly pressure is what I mean. It works beautifully in animoog cos u can trigger a note, with initial velocity and then keep the pad held down and change the pressure to mod the sound in animoog.

So Nym. Ur saying it can't be done? I don't exactly get why for example pad A1 set to Note C1 by default (cant remember if thats the correct note off the top of my head) works fine. But if I change it to say c#1, note and velocity send fine but no poly-pressure message gets sent... I need to be able to get it into those low notes like C-0 somehow to get those wobbly basses going, but the lowest pad note default is C1

Can I change the master or default note of a pad somehow? Instead of doing it through the main screen for the current track only.

i haven't experimented with this because i use an external keyboard and don't often use poly pressure. maybe a FR is in order to allow SEQ EDIT: TRANSPOSE to also transpose the corresponding POLY PRESSURE data.

Yeah this is the first time I've touched on poly pressure. But as I just discovered today the magic of the mpc pads for controlling the animoog instrument it's def worth getting it dialled somehow.

That suggestion of yours would do it I think..cheers

yep its actually after touch you are talking about. There is two midi standards for it but pretty much the same thing.
Do you know what the STATUS BYTE is? thats the difference. lets not get into MIDI DATA bytes and keep it simple, no one likes hexadecimal anyways.

If its per note then after touch, or for the whole midi channle then yeah its called poly pressure, but really its after touch as well. you just call it poly pressure.

In JJOSXL just MODDE + PAD 9 to go to midi settings and turn on after touch. THis will enable your so called poly pressure.

And answer of setting midi note number is easy to , just highlight on the main screen the MIDI note when track is set to MIDI. You can then use data wheel to set midi note of pad..

after touch rocks i use it on synths as well. makes for very expressive evolving stuff.

I just came across something about aftertouch on the 2XL JJ OS.

The pads no longer send channel pressure!! They send poly pressure unless you disable it in the midi menu, but very few synths respond to poly pressure, I often use the pads to program synth lines with aftertouch since it is really easy to get accurate varying pressure compared to my keyboard, and now I cant!!!

Apparently an instrument program will send poly pressure, but needing a blank instrument program just to use the pads as a midi controller for an external synth is whack. I was doing this with my 60 forever, now the 1000 doesn't have it? BULLSHIZZ.

I hope they add a selection in the midi menu, where you can choose Midi out Poly or channel pressure/Aftertouch.

Thanks bliprock, after touch is enabled and the process u have mentioned of changing midi note is the one I have been using.

What has been throwing me is that in animoog, in the mod settings, the one that matches the touch screen sliders (the main sound modifier) is called poly pressure. There is an option to use Channel pressure as a mod control but from the mpc it seems to have no effect, but when set to poly pressure it behaves as it should provided i leave the notes on the pads set to default....

....Which is I'm guessing is for the same reason as outlined by elmacaco above. If the pads could send channel pressure then it would just be a matter of changing the mod parameters in animoog.


A simple master transpose on animoog would fix all this haha. Perhaps I'll send a feature request their way too.

yeah to me its like the MPC needs to have after touch on, to work with the channle pressure.

ok your doing good crazy stuff with the animoog there, you can insert those events in the sequence window you know and set for note in poly pressure.
