You got right about MBHP PBCs they will be better, i say about Krause PBCs coz i dont notice orginal boards only some info on page that u give link now i know where to click to get schematic :P. Thanks a lot now i must order parts and start to make "my midi IO 128"

ok this is good one i decide to make this one build upon Roman Krause PCB, and i have another question: can u tell me how to put button into this ?

Hi i want to do mini version of midi-keyboard, just couple of switches ex. 10 and nothing more no LED display for program and this kinda stuff. I explain maybe for more understanding :d when i push 1 swith florboard send via midi information that key was presed and change some append to this key instruction (ex. on/off some effect ) just like in standard midi keyboard but i want to this in a smaller version packed in case that handle step on key coz i will pres button by my leg so midi keyboard havevs quite smal key to do this . I will be very aprichiate if some one will give me some schematic, tip ect. how to build this. It will be very good if it can be done without programing ( iam sux in this, and don't have any programator ), my friend tells me that it posibly. He say some about matrix 3x3 for switch that will be send signal to converter and him send to comp. midi information
