NON velocity sensitive MIDI keyboard

Postby Jumpeyspyder » Mon May 24, 2010 7:37 am

Are there any available these days ?
Ideally I want one with 76 keys so that I can wire up alternative switches and trigger samples by plugging in a patch lead.

DX9 springs to mind for 61 keys. 76 might be hard to find...not sure what you mean by alternative switches, but I'd have thought most keyboard/sampler setups would allow you to turn velocity sensitivity off. What are you using to play the samples...?

Thanks BJG145

DX9 would probably work but I'd feel guilty butchering one.

I'm looking for something that I can buy easily and cheaply preferably just a controller keyboard.

My plan is to take the plastic keyboard off and wire the switches to a patch panel and use a shorted lead on the other side of the patch bay to make the samples trigger.

I believe that velocity sensitive keyboards have sensors rather than switches which would be harder to mod.

Take a look at the Doepfer DIY stuff. Specifically, the CTM64 - Just add switches

No need, it would be a mercy killing.

(Most of the keyboards I've seen seem to measure the velocity by the difference between breaking one contact and making another...something like that anyway. But I don't think rewiring a typical design would be more difficult than rewiring a fixed-velocity one.)

Yeah, the time it takes to break the top contact to the bottom contact is a measure of the speed as which the key is travelling - hence "velocity".

Also remember that many velocity-sensitive keyboard have various velocity curves including a ‘maximum velocity however soft or hard you hit it’ option.

I switch to this option on mine when checking synth presets for distortion (although judging by some sample libraries not every designer does this )

Thanks All for the replies

The CTM64 Contact To MIDI Interface suggested by MarkOne seems like just the ticket.

I've got this function on a touch sensitive keyboard the early 90s. I'd be very surprised to find any MIDI keyboard controller currently available that did have the option to set a constant velocity/MIDI value for a key press.

Perhaps you’ll be surprised then Matt

Just did a quick search and the Novation Nocturn has this option. For its PDF manual:

“Curve: Click to select the velocity curve of the keyboard. The settings available are: Loud 1, 2, Medium 1, 2, Quiet 1, 2, and fixed velocities of 8 to 127.”

I suspect there are plenty more out there!

Beggar me - what a time to miss out the very important word "NOT"!

As in "I'd be very surprised to find any MIDI keyboard controller currently available that did NOT have the option etc etc"

Sorry - shouldn't post late at night and/or not proof read my posts on such important topics

Absolutely not, what?

And it appears I posted the original gaffe @ 4pm... So I'm also way off when I tried to blame it on late night posting. Heigh ho - I think I'll try and blame it going "a bit darkside" and discovering guitars instead...

We'll let you off this time with a caution - perhaps your typing is velocity-senstive?
