Hello All Midiboxers, and T.K. ! I was built my little MB with 5 pots and 2x4+16 buttons (no AIN modul, pots on the direct input, other 3 are on Gnd) and one DINx3 and a DOUTx3 with 16 leds. My goal to control my Yamaha PSR3000 (Like Tyros1) some functions quickly, not from instrument's menu.These like : mic. volume, midi ch.1-2 volume,effect depth, cutoff/reso of upper1-2 tone,vocal harmony balance; to switch toggle on/off microphone effect, mic.vocoder on/off, vocoder type, and so on... First I was reassembled midibox64V2_4 main1.asm to mainMy.asm, then translated to 5pot_24but.hex.That was I uploaded to PIC, and I'ts works, but I have some questions : How can I tell to buttons my special meta events in edit mode on the box? I can edit only last 3 byte . My instument parameters which I must send for example : F0 43 10 4C 03 00 0C 7F F7 F0 43 10 4C 03 00 0C 01 F7 in toggle mode. But when I receive with MIDI-OX the button-command send always F0 43 10 5C 10 10 31 76 F7 / F0 43 10 5C 10 10 31 00 F7, and only the last byte can I change in edit mode. Where can I say to the box the correct values, and how? Or I must use vmidibox to configure , and send sysex -editor dump? Must I mark the "learn" checkbox, if I want to learn that button or pot later? Other question : If I turn the pots, the 5 pot's have different functions, it's ok. But one pot movement send to the all 8 midi chanel volume, pan ,or others. How can I tell to a pot, if only to one midi chanel must send data? I apologize my bad English, and for much questions. I hope are you understand my problem. Thank you for help in advanced from Hungary : Pisti (venkecske) <a target="_blank" href="http://kepfeltolto.hu/i/?8156"><img border=0 width=100 src="http://kepfeltolto.hu/i/?8156&t=thb" /></a> (If you think, I can sent the mainMy.asm file to control my config.)
