Custom made keyboard for midibox SID

MIDIbox SID
1

Hello everyone :wink:

I finished my MBSID and MB64, I’m planning to add a keyboard to them. Since I read the reply of TK to a post of a midiboxer who wanted to have buttons interfaced to DIN module capable of sending midi note on, I’m quite sure that because I don’t possess experience with PIC assembler neither time to learn, this is going to be a hard work :smiley:

So I thought of routing note on message to midi in of MBSID and MB64 from this midi encoder http://www.geocities.com/midiboutique/  (mkc-MG).

I could build a matrix of buttons for the MBSID and connect it to a mkc-MG, then route the midi out of the encoder to midi in of midibox.

The same for MB64, with another matrix and another mkc-MG but I’m using push buttons from arcade games for this one, to turn it into an impressive keyboard midi controller :smiley:

It’s an expensive way out (100 € for both encoders), but I need a keyboard for my midibox, do you know if there’s a better and cheaper way to achieve my objective? I don’t want to use casio or similar things because I need a more personalized keyboard (very small for MBSID and very big for MB64) Thanks!

Sounds doable.

And 50e/board isn’t really THAT bad price :wink:

Hmm.. I thought it was a discontinued long time ago, but http://www.cedos.com/e510_midi_chip.htm - Cedos has these E510 chips for sale.. can’t find the price though. It would even have velocity sensivity ::slight_smile:

And how many buttons do you need for your MB64? You could EASILY configure buttons to send midi note commands using Vmidibox64: http://www.midibox.org/mios_tools/

Thanks Moebius! As always good tips from you :smiley:

I don’t know if common normally open pushbuttons are reliable for good velocity sensing :smiley:

Yeah, you are right ;D

Switches need two poles, so velocity can be calculated from the time, what it takes to switch from one position to another.
