Hi everyone! Just a quick update: after a good night of sleep, I found a bad joint directly connect to the RES# pin in the SID chip. After fixing this, now I am able to complete successfully the "mbsid interconnection test v2" application, and confirmed that all SID pins have the correct voltage during the test. Also, when I run the "mbsid_testtone_v3c" application I get a triangle waveform from the SID output, as expected. However, when I run the "setup_6581.hex" I get only a "click" sound and the sysex message "f0 00 00 7e 40 00 01 f7" every 4 seconds. I tried to upload the other files from the "midibox_sid_v2_044", but the behavior is always the same. Any hint or tip? Is the sysex message "f0 00 00 7e 40 00 01 f7" the expected behavior from the application "setup_6581.hex"? What does this sysex message mean? Thanks!

Hi everyone! I am a complete noob and I have just build my first MidBox SID (just the Core and the SID modules, without a LCD). Unfortunately I am not able to produce any sound! Could you please help me? Below are some tests/information of what I am getting while trying to debug the MidiBox: 1) In MIOS Studio 2.4.6, I get the following message ( so I think that I covered the "basics"): Operating System: MIOS8 Board: MBHP_CORE or similar Core Family: PIC18F Bootloader is up & running! 2) When I run the "mbsid interconnection test v2"application, I can confirm that all SID pins are set to the correct voltage, with the exception of pin "RES#" (always at 0V). 3) When I run the "setup_6581.hex" I receive the sysex message "f0 00 00 7e 40 00 01 f7" every 4 or 5 seconds together with a weak high pitched sound followed by silence. However, when I play my MIDI keyboard, no sound is produced. Unfortunately, I have no idea of any additional test that I could perform. If you could give me any hint or tip it would be highly appreciated!
