what is "release velocity "

hi can anyone tell me here what is "release velocity " ? what mean by "release velocity off " or "release velocity on " ? Is it a midi message or midi controller ?
Thanks !

From what I remember, it's a parameter such as velocity, described in the MIDI specifications that hardly ever gets implemented in hosts - for instance, while Logic will allow you to actually record release velocity, it won't display the values anywhere, so editing is impossible. I think it's similar in Cubase.
But then, there's hardly any MIDI keyboards sending release velocity data anyways.
My wild guess would be that it's been originally meant to support techniques such as slowly releasing a key on a real piano, which would result in quite something different than just a plain note off. Seems to be one of the forgotten things in MIDI land...

Well, normal velocity is at the start of a note - how fast/hard the key is pressed. And release velocity is at the end of a note - how fast the key is released.

It can be usefull on string pads where you modulate the ADSR attack and release stages according to how you play. For example, playing fast and hard shortens the attack and release times, and playing slowly/softly will lengthen attack/release times.

Another use for release velocity is to trigger a sound when you let go of the key. For example, a guitar patch which plays normally but has a string squeak when the note is released - the higher (faster) the release velocity, the louder the squeak.

I don't know of any VST instruments that respond to release velocity, there are none in my collection, but hardware synths have been using it for years. My Kurzweil has it and my old Roland had it.

BTW Sascha, I think it can be edited in Logic's event list if you change something in one of the menus. Can't remember what right now and I'm not in front of my music computer at the moment. I know it could be edited in Notator... Ha ha... Remember that..?

:wink:

Release velocity is useful for controlling things like string pulloffs, or sounds that have a controllable release event, that sort of thing.

For example you could setup a Bodhrán to do a dry release with one release velo layer, or a little flam on a different release velo, and then you've got some control of that.

Watch in MidiOX or your piano roll if it shows events. Look for the note-off messages, and notice that the note-off also has a velocity. That's the release velocity. You can have 127 different release layers in a sample, if you're nuts :-)

I know of a piano patch that simulates the sound of the action falling fast on a quick release. On a real piano, if you let off the keys quickly, the action makes a noise. To do that kind of variation you need release velo.

"on" or "off" probably means you can turn it off for the whole controller.

what is "release velocity "?

how quickly ya let go of it... the key, that is :)

really? Most of mine do. Yamaha, Roland, Alesis, but not the Oxygen-8; I haven't tried the keystation-61.

Hm, ok, maybe I just didn't notice becaúse I never monitored it or utilized it in any way.

As I see only Alesis makes release velocity on their keyboards. I would like to see that option on this one http://www.studiologic.net/vmk-88.html
It would be perfect because this one has aftertouch, too.

Cakewalk/RCG Audio Z3ta+ does support release velocity (€188 including 25% VAT on thomann.de ffs. Anybody got a cheaper offer/coupon code or something?). Just checked my CME UF6 does send release velocity. i'm positive that all my other keybs do as wel, with the very possible exception of my cheapass MK249C2 which is lying around unused here. :)

Fixed or 1-127?

Both my K5 and my Matrix-6 transmit release velocity.
The softsynths I have that support release velocity are Xphraze and Reaktor (if the instrument's built to use it).
