Hello, i am starting a project in which i need 36 pushbutton to command a software by midi. I was thinking using the MIDI io 128 program. Could you please confirm the hardware i need please? :-\ - 1 core - 2x DINx4 (64 digitals inputs for 36 used) This midibox will be added in a midi chain. Do i need other things? Thank you for your help, Regars, Alex

Hello, I have a few spare PIC18F452 i won't use. They are new. I burnt the bootloader. price: 12 Euro each (that is the price i paid them). Free shipping... contact: alexglvr@yahoo.com Alex

Hello, i have the mplab suite from pic, a few 18F452 pic's and the ICD2 programmer. I would like to upload the bootsrap into the pics. I remember to have found a tuto on ucapps.dea, but can not refind it ??? Thank you for your help, Alex

Hello, I am working on a midi pedalboard for guitar effect switching. The idea is to have presets memorized in it, regrouped in banks of 10. 10 switchs will permit to select the wanted program in a bank, and two other switches (Up and Down) will permit to select the wanted bank. (It is that way most of guitar pedal board work) Do i have to change the core program for that? I am ok with the need of : - a core module - a Din for the switches - a Dout for the leds - a Ain for an optional external expression pedal I would like to be able to define the presets of each banks directly on the pedal board (without the use of a computer). Therefore i think i need the LCD module to be able to do that, don't I? Moreover, do i need the Bankstick to memorised my presets? I want them to be kept even is the board is not powered... Each preset will have to command up to five midi devices. Is it a pb? At least, i have to have in it 4 commanded switches to replace my amp control. How can i do that? the midi device commanded by the external expression pedal (analog) can change according to the preset... here is an example of a preset: - Switch1 on - Switch2 off - Switch3 on - Switch4 off - external midi device 1: prog114 - external midi device 2: no change - external midi device 3: prog 10 - external midi device 4: no change - expression pedal command the whawha effect on the device 3. Sorry for all these questions, and this long message... Thank you for your help. Alex

Hello, i am about to start a project. The goal is to command the registeries (i am not shure of this word..., let's say the 'sounds') of a digital pipe organ (computer software)... i will then have 1 switch (single position) and 1 led per sound. when a switch is pressed, the associated sound must be put on/off. The corresponding led must follow the state of the sound... at this state the midiio128 seems to be a good choise... a bit more complicated: i can save configurations on the organ software. i would like that, when a configuration is recalled, the leds associated to the good sounds light on... about the midi configuration : computer (which plays the sounds): channel 1 keyboard 1: channel 2 keyboard 2: channel 3 keyboard 3: channel 4 foot keyboard: channel 5 but what about the midibox? the Dout for the leds must respond both to the computer and to the midi box itself... is it possible with the midiio128? a last question : is the LTC module necessary? i already have a midi chain, and i does not anderstand the aim of the rs232... thank you for your help... Sincerely, Alex

Hello, thank you for your answers... will search on MIOS and study all that.... thank you again Alex

Hello, thank you for your help... I need midi for my next tube amp. My goal is to build a very versatil amp with lots of options and even some motorized pots... The goal is to programme the wanted sounds and correponding adjustment and to recall them by using midi.... Furthermore, the midi pedal board can in the same time command other things like the associated reverb ;) I will look again at the ucapps site, but i didn't find source code... I have other things to add to the programme, and do not want to use a second pic... Moreover, i like anderstanding how things work.... ;) Thank you again, Alex

Hello, I made a tube guitar amp, and would like to add on it the midi protocol in order to be able to control it with a midi footswitch. I was thinking using a pic, as i am very familiar with them. Where can i get good informations on the midi protocol (from how to use it to how to code it...)? Thank you for your help, Alex
