plosive - "If you sequence your drums (or key parts) via a keyboard or a padkontrol, etc. the midi velocity for every step is recorded and will be transmitted during playback, along with any Accents."

Do you mean if I use a keyboard to enter the notes of a synth part on my EMX, while the EMX is recording, then the EMX's internal sequencer will record (and later playback) not only the note on/off, and note-number data, but also the velocity?!!! Or do you just mean that if I use a seperate (external) sequencer - like a computer program - which has the ability to record & playback velocity data, then this velocity data will be transmitted to the EMX on playback of the external sequencer? Obviously the latter will work, but if the EMX can actually record velocity data, I'm amazed I overlooked this feature! Was it just because I hadn't turned off the accent parts when I tried to do this, and therefore my EMX was always sending out 127-velocity for every note command, whatever velocity it was recorded at?

Can't wait to get home to try this one out!

nono, sorry for the confusion.. i meant if he was recording the midi input into his software sequencer while laying down the beats.. not the electribe recording directly..

here are the scenarios:

padkontrol (or kb, etc.) midi out-> electribe midi in (triggers parts, no velocity is recorded into electribe)

padkontrol (or kb, etc.) midi out->electribe midi in + electribe midi out->computer (transmits midi vel)

electribe only: steps with Accents -> midi out-> (transmits midi vel (you can change each step accent amount via level on accent part/steps))

electribe only: steps without Accents -> midi out-> (no velocity is transmitted, just note #)

electribe only: triggering samples with part keys or key trigs -> midi out (no velocity is sent)

thanks so much, this is enlightening.

How did you find this out? I didn't see it in the manual. Again, thanks plosive.

OMG, is this a dj forum ? :lol:

The EMX has only 2 velocities levels compared to standard MIDI which has 127 levels (1-127).
The velocity value will differ if ACCENT is On or Off.
WIth ACCENT ON the value will be between 100-127
With Accent OFF the value will be between 100-30

It is the Level knob that defines these two values
When the Level is full left there is no difference between ACCENT On and Off, they will always output a velocity of 100 (well 99 and 100, actually).
The more you move the Level to the right the more difference you will hear between Accented and non accented notes.
At the far right side, accented notes will have a velocity of 127 (max) and non-accented will have a velocity of 30.

This is normally a global setting, but with the motion seq, you can assign a different level for each step.
So, you can have a velocity from 30-127 for each step, but this is global for all synth parts. The second accent track will be global to all drum parts.

Edit:
I forgot to metion that a part with accent disabled will always output a velocity of 100.
So to summarize.
With part Accent switch on:
Accent On: velo 100-127
Accent Off: velo 100-30 ( not 30-100 !!)
With Part Accent switch Off:
velo = 100

Actually it's possible to record the velocity from an external keyboard and send it back to an external module.

The trick is to convert first the note velocity to a cc7 (which is the level) that will be recorded as motion data.

Then, on play back, use the last cc7 value for a given channel and replace the velocity by this value.

This can even be extended by taking into consideration the Accent track, by giving a boost on accented notes and dim non-accented notes.
It's even possible to totally bypass un-accented events, to make a pattern more or less busy.

For the drum track it's just a little more work as we need to use NRPN to set/ retreive the velocity of each drum part, but the idea is the same.
