Guest neuronet Posted March 14, 2003 Report Share Posted March 14, 2003 Is it possible to have the MBHP send midi on/of signals? I'm asking because i'd like to build a keyboard midi controller using a keyboard matrix connected to the pic. any ideas? Quote Link to comment Share on other sites More sharing options...
Steven_C Posted March 14, 2003 Report Share Posted March 14, 2003 I don't think building a midi keyboard is a viable option.......where are you getting the keys from........and what about the velocity sensors.......midi is not just on and off data (though any midibox on Thorsten's sit can be used to do this with pushbuttons) there are sensors in a real midi keyboard that sense the speed that you hit the keys at, and good ones have aftertouch sensors too. But this is just advice, its up to you. (I dunno whether velocity is possible with these designs though)bye, from Steve 8) Quote Link to comment Share on other sites More sharing options...
jasper81 Posted March 15, 2003 Report Share Posted March 15, 2003 My experience tells me the following:It's very well possible to create your own midi keyboard. using buttons as keys ( like a roland mc-303) it actualy is very simple...BUT if you are planning on building a pianolike keyboard...:) look at the post before this one. Ofcourse it's possible to create velocity detection..by use of piezo's or electromechanical devices...but I'll bet you...that when you add all the costs for the components together + the amount of time you spend on designing + building +tuning etc. together, you can buy yourself a big cool midikeyboard, which will probably work even better.What IS a good option is buying a cheap midikeyboard...and add a midi box inside it....so you can add knobs buttons Leds encoders or whatever...greetzJasper Quote Link to comment Share on other sites More sharing options...
Guest neuronet Posted March 15, 2003 Report Share Posted March 15, 2003 perhaps i should have been more specific. The project i have in mind is a personalized guitar-style midi controller simaler in shape to an AX-1. I don't need the velocity or aftertouch functions, just keys that send on/off data. Nothing more. I have keys and could easily construct the casing. Quote Link to comment Share on other sites More sharing options...
Steven_C Posted March 15, 2003 Report Share Posted March 15, 2003 cool, sounds like the midibox platform will serve your needs perfectly then! ;Dbye, from steve Quote Link to comment Share on other sites More sharing options...
Guest neuronet Posted March 15, 2003 Report Share Posted March 15, 2003 So what's the verdict? What do i need? Am i going to need to learn the PIC assembly in order to generate the on/off data? or is there already functions in the MIOS that'll make it easy?

TK. Posted March 15, 2003 Report Share Posted March 15, 2003 MIOS has a user hook called "USER_DIN_NotifyToggle" which is called on every change. Generating On/Off data is a piece of cake - see the AIN DIN DOUT example :)Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Guest neuronet Posted March 15, 2003 Report Share Posted March 15, 2003 right, thanks Thorsten ;) Will hopefully be able to start on it sometime this week. Quote Link to comment Share on other sites More sharing options...
