is making a MIDI drum pad possible?

[SoulFood]

Hello!

Could someone tell me if it is possible? if it is, is it possible with the 64 or only LC?

has anyone ever done this?

what would i need to make it velocity sensitive?

this is what i'd like to make, if i didn't write it correctly...

Thx so much!

There are some free e-drum projects on the net.

These links might be useful:

Thx for the reply raphael!

That looks like a great project! But i would just like to have a few trigger buttons (like the one on the link in my first post...)

Would this be possible?

Thank you!

Triggerbuttons without velocity sensivety can be realized with MIDIO128, MB64, MB64E.... No problem.

To get velocity information you need piezo triggers (used in the edrum project. A analog circuitry is needed like described there).

OR you use special buttons. They have two contacs. One is opened or closed (depends) when you start to press down the button. The other one is triggered when you have pressed down the button. You can get the velocity information by measuring the time between these two states. I don`t know if anybody has tried this with a Midibox.

I think to achieve a accurate time measurement the buttons have to be connected directly to the core (no shift registers) and you have to assign an interrupt to them. So I think MIOS is no option for such a project.

There is a C based project which provides velocity sensitivity (-> http://www.midibox.org/forum/index.php?topic=5835.0), but some code need to be added in order to control analog inputs as well (-> http://www.ucapps.de/mios_c.html)

Phew... Meanwhile there are so many projects that I couldn't even remember this one  :)

Thanks Thorsten for correcting me. It seems that MIOS can really do everything...

WOW!!!  ;D

Thank you so much!

If i would build an LC, would I need a seperate core for the 16 buttons?

And another question (maybe i'm pushing it with this-one  ???), is there a way i could use an LCD to show me how I named the tracks in Cubase?

Thank you!

I've moved your post to the old one, because it's not really useful when you spread your questions over the whole forum.

If you have some programming skills, you should be able to merge the C based MIDIbox LC application with the DIN Velocity project (this is not trivial, but it works)

Without programming skills, the easiest way is the use of two cores
