Hi! It´s looks to be XTAL 10MHZ, C1, C2, if out of frequency or internal bad contact can reboot the CORE. I hope this help you.

Hi, May be this is not new for advanced users. This XR-2206 Monolithic Function Generator is very usefull to use with analog out module, for example to control 3x XR-2206. Low-Sine Wave Distortion, 0.5%, Typical Excellent Temperature Stability, 20ppm/°C, Typ. Wide Sweep Range, 2000:1, Typical Low-Supply Sensitivity, 0.01%V, Typ. Linear Amplitude Modulation TTL Compatible FSK Controls Wide Supply Range, 10V to 26V Adjustable Duty Cycle, 1% TO 99% Waveform Generation: Sweep Generation AM/FM Generation V/F Conversion FSK Generation Phase-Locked Loops (VCO) FM OPL3 and SID are hard to find parts, so this XR are too cheap and easy to find. Any inputs are wellcome, let´s do it. XR2206v103.pdf XR2206v103.pdf

Yes, I discovered this today that we dont need core connected to listen the sounds from keyboard, this is too simple, I did many search here but there is nothing about this.

That´s OK I´m stopping by now and reading/learning: Introduction to uCApps.de http://www.midibox.org/dokuwiki/doku.php?id=introduction_to_ucapps.de - recommended reading! 98% of all newbie-questions in the forum are answered in here Thanks for all inputs

OK this first lesson I got it and is OK. Now the second lesson. Was loaded the MIDIbox 64e I'm using the MIOS Studio midi keyboard controler, MIDI has DATA out but no audio on the PC. There´s only 5 pots in unmuxed mode(J5)

Yes Pin 25 is TX sorry for my confusion. mios_v1_9f_pic18f4620.hex was programmed s_v1_9f_pic18f4620.hex was uploaded You said "Next is to upload your application" What this mean?

Hi!! There is a PIC ID Value Calculator here http://www.avishowtech.com/mbhp/idgen.html For PIC18F4620 PIC ID Header: 0000 0000 0000 0000 This is the same I´m using but no way, no DATA on pin 25. This is the LCD message start: MIOS V1.9f © 2007 T.Klose and them READY I´m feeling too bad, why me???

Thank you for your help. Elnec SmartProg2 is a profissional programmer, this is best them ICD2BR, I have beem programed DSPIC/PIC/ATMEGA88/AT90S2313 and many others. Flash Microcontroller Programming Specification "39622F.pdf" page 9; "Users may store identification information (ID) in eight ID registers. These ID registers are mapped in addresses 200000h through 200007h. The ID locations read out normally, even after code protection is applied." SmartProg2 GUI let user store ID location. Could someone provide correct ID location for 16F4620? ID Location 1=? ID Location 2=? ID Location 3=? ID Location 4=? ID Location 5=? ID Location 6=? ID Location 7=? ID Location 8=?

Now LCD is READY not DEAD. I´ll try to explaim step by step all procedures for newbie like me. Please look PDF for more clear undestanding, english is not my native language and some time I have some difficulties to explaim what I´m thinking. 1-I made my mbhp_core_v3b using an universal PCB this is very easy to build and better them protoboard, anyone can do this without buyng an industrial PCB. 2-For people like me that have a programmer like SmartProg2, you must check "Ignore Microchip Recommendation to let most Significant Niblle of each ID to be Fh" this is the secret for not have anymore "Received Unxpected MIOS SysEx message" 3-Take care with MIDI IN/OUT, "Rear View" means exatily "Rear View" see this in PDF atached, that show MIDI Front View. But here I have no "FLOWERS" there´s no DATA outgoing pin 25 TX, PIC is not dead, I did MIDI OX tests and before upload mios was receiving DATA on MIDI MONITOR IN Well, any suggestion??? Upload.pdf Upload.pdf

I did software implemented loopback test with MIDI OX, everything OK. I´ll try this tomorow MIDI-OX.pdf MIDI-OX.pdf

Fixed? this is not true... Started again Erased all PIC18F4620 LCD is new one. Uploaded mios(look pdf) Everything looks ok but, display is dead and no sound. MIDI IN receiving DATA but MIDI out there is no DATA, PIC clock is 10mHz. What is the magic way to work? Upload.pdf Upload.pdf

I fixed the problem "Received unexpected MIOS SysEx message = 00007E407001F7 expected = 00007E4002" Was very easy the solution, "Upload Option" "Device Option" change to 70 for 18F4620 Midi input/output comunication is ok, but no sound, any ideia? LCD is dead, this is an old one, will buy new LCD. Thank for all inputs.

Manual mode, Delay 500, but LCD is dead.

Thanks for too fast answer but same problem here. I have DSO 100mHz, pin 25 TX and pin 26 RX are OK

Hi! I have SmartProg2 and PIC18F4620 was programed with bootloader_v1_2b_pic18f4620.hex. I did some search but was not possible to fix upload error. Can someone point me to the rigth direction? MIOS.pdf MIOS.pdf

Fantastique!!!! Could you share all schematics....especially how you implemented the keyboard!

Montei meu protótipo com placa universal, estou usando o PIC18F4620 comprei na Farnell, tenho um programador SmartProg2 e mandei bala programou 100%, agora só falta fazer o upload do MIOS, ai que começa o problema, meu PC não tem porta MIDI, andei lendo no forum e vou ter que comprar uma placa de audio com MIDI, minha pergunta é: Se eu tenho um programador profissional será que dá para gravar o MIOS direto sem o PC?

Construi meu primeiro sintetizador analogico quando tinha 17 anos, apresentei a varias bandas e todos davam risadas do som esquisito que fazia então abandonei a idéia, hoje tenho 50 estou abrindo minha empresa de projetos e tenho algum tempo para me dedicar a algum hoobie e este aqui foi um achado, simplesmente brilhante. Tenho uma duvida em relação ao teclado, não vou usar midi vou fazer meu proprio teclado com chaves, já comprei um perto da Santa Ifigenia por R$40 , qual modulo devo usar e como calibrar as notas? Tem muita informação aqui e ainda não deu para digerir tudo.
