Bare Bones Midi Keyboards

[robinfawell]

I am looking for 2 bare bones keyboards that have the following features.

Velocity sensitive.

New or used.

No cases if new, cases could be removed if 2nd hand.

I want the 2 keyboards one above the other in normal organ position.

76 keys.

Any suggestions.

I have found that it is possible to buy Fatar keyboards (without electronics) eg TP 10 from Doepfer in Germany.  They make their own midi controller keyboards using Fatar keybeds and schematics for the smaller keyboards are provided on the Doepfer website.

The schematics show 2 contacts per note.  These operate in conjunction with make and break bus bars.  I am assuming that the system will provide velocity sensing with suitable strobing.

There is a reference to the black keys giving a different velocity response to the white keys.  Doepfer have a way of equalising this.

I would be very interested if anyone has a method worked out to provide velocity information using Midibox.

Check out QBAS's code for a velocity sensitive scan matrix. Search for qbas keyboard and you'll see it  :)

Tell us more about these keybeds :D

I've put the schematic URL on my previous post.  Doepfer can provide 88 and 76 key versions.

Here is an email from them.

"we have keybeds with 88 keys and 76 keys on stock at the moment (Fatar

TP10MDF) .

We order the version with 88 keys in regular intervals because we use them

in our Masterkeyboards PK88, LMK2+ and LMK4+

We have also two samples of the 76 keys version on stock at the moment but

there is no suitable keyboard electronic available

so far. The keyboard electronic for 76 keys will be ready in about 3-4

months."

You can see the various production models on the Fatar website.  However you need a password to see schematics.  I have contacted them. but they ignore you.  They're only interested in OEM's.

Thanks for the velocity reference.  Have to go now.
