Empty PIC?

Testing/Troubleshooting
1

I’m trying to get Step A going for the Midibox SID.

I think I loaded the MIOS okay.  After programming, my LCD read “MIOS 1.4” and then “READY.”.

I then changed by buffer size in MIDI-OX and tried sending the SID v1.5b to the box (I am using an pic18F).

It took about ten minutes to program and all I get on my display screen is the following:

P  1  C  1  1—

<empty>

Any hints?

Thanks

Hi

The PIC is ready to rock!

P  1  C  1  1—

<empty>

This is the defult display when MIOS runs the SID app. Try using jsynth to load a patch in to the PIC. If all goes well it should display the patch name where “<empty>” is on the LCD. You can also send MIDI programe change to the core. This should change the “P 1” value (ie send programe change 5 and the LCD should display “P 5”). With jsynth you can also change the MIDI channel and device ID (“C 1  1—”). “C” = midi channel number, and “1—” is the device ID for each SID if you are using a multi SID setup.

10 minutes is a VERY long time to load the SID app into the PIC. Mine takes about 20 sec. Go thru all the instructions regading using MIDI-Ox word for word, This should cut the upload time to less then 30 sec.

Best of luck

Thanks Rowan!  

I still have some more questions, though.

  1. With only a MIDI keyboard connected the MBSID, should I be able to edit SID parameters?  I see the

P 1 C 1 1-- screen but can’t get to the parameter menu.  Perhaps my DINx1 is not working?

  1. Without a bankstick, how do I download a single patch to the MBSID with Jsynth?  How is everything connected if I want to use a MIDI keyboard to play notes but control parameters in realtime with Jsynth?

Thanks for the help - I’m new to MIDI.

Ah ha!  There was a problem with the DINx1 - an unsoldered clock connection.

I think I’ll be fine from here.

Thanks
