my changes to CHORDORG.TXT are ignored, why? #14

Open lushsounds opened 6 years ago

lushsounds commented 6 years ago

I have the following problem with my new Chord-Organ, which I bought second hand a couple of days ago: No matter what I change in the CHORDORG.TXT file, the module will still play what it has played since I have it. I made a test and made all 16 chords equal, it will still play the default 16 different chords. What am i doing wrong? Thank you in anticipation.

Do you know which firmware is on it?

You can get the latest from here : http://polyfather.com/chord_organ/

lushsounds commented 6 years ago

sorry for the late reply, I was away: No I don't know which firmware is installed. Is there a known bug regarding my problem in an older version? Anyhow, I will check if the latest firmware will do it. Thank you.

Now I am having difficulties uploading the hex file using Teensy. The file Chord_Organ_0.6.hex is too large according to a Teensy error message. Please help!

Normalised commented 6 years ago

Can you tell me :

  1. What OS and Version
  2. What version of the Teensy Uploader
  3. The size (in bytes) of the hex file on your system
lushsounds commented 6 years ago

I am using Mac OS X 10.11.6 The Teensy Uploader is version 1.4 The size of the hex file is 200 KB

lushsounds commented 6 years ago

ok after my Teensy got blown, I have a new one attached now and everything is working, except: The Chord Organ's chords work even with a freshly formatted and empty SD card. I understand that the default chord list and settings are loaded from firmware. So somehow the file on my SD card gets ignored. What could be the reason? Please help.

Paging @Normalised - wondering if you've seen this before?

Normalised commented 6 years ago

No I haven't. There's a couple of things I would check.

  1. Is the CHORDORG.TXT in the root of the SD card
  2. What is in the file?
  3. Does Radio Music work?

The RM firmware has a couple of handy features at startup to help debug if the issue is a basic card reading problem or if its the content on the card, if you see the very bottom of this page :

lushsounds commented 6 years ago

thank you @Normalised again: no CHORDORG.TXT at all on the SD card, but Chord Organ works with the preset chords.

Loquelic commented 6 years ago

Hello @Normalised on my case the chord organ doesn't create the CHORDORG.TXT in the root of the SD card. I installed the latest firmware now but still not working

Normalised commented 6 years ago

What about if you put your own CHORDORG.TXT on the card?

If there is nothing on the card then it will use the default settings that are built into the firmware.

If you go to this page : http://polyfather.com/chord_organ/

  1. edit the chord settings show in the text box
  2. Click DOWNLOAD CONFIG to download the CHORDORG.TXT file to your computer
  3. Copy this to the SD card
  4. Reboot the module with the SD card and new TXT file.

What happens?

TomWhitwell commented 6 years ago

I wonder if the module will work as you describe if the SD card socket is not connected (a missed solder joint) or the SD card itself is faulty.

The Radio Music firmware is obviously much more dependent on the SD card, so this would normally be identified sooner. Closely check the soldering around the socket - the tiny pins. It’s not a very common problem but worth checking.

Loquelic commented 6 years ago

OK, I re-soldered the tiny pins and I can finally see the txt file, but i still can't hear nothing, i don't understand, i can see the leds responds perfectly but without sound, just a noise

lushsounds commented 6 years ago

@Normalised: If I put my own CHORDORG.TXT on the card, it gets ignored. So maybe it's what @TomWhitwell says, that the SD card socket is not properly connected. The modules behaviour is slighly different though between having no SD card in the socket and having an empty SD card in the socket. With card the module starts almost immediately after powering. Without the card the four lights flash one after the other before the sound comes.

Loquelic commented 6 years ago

Yeah it responds as you said, but without sound, I'm missing something

Thonk-Steve commented 6 years ago

This may have been covered, but you tweaked the trimmer on the back for gain level?

get and screwdriver and try adjusting the blue trimmer on the back, it's just a volume knob.

Loquelic commented 6 years ago

yeah i can hear some chord now but the noise is very loud

Thonk-Steve commented 6 years ago

is the quiet chord reacting as you'd expect to the controls?

TomWhitwell commented 6 years ago

Some Possibilities: A missed solder joint Two resistor values swapped A diode the wrong way around A very thin solder bridge somewhere A chip the wrong way around A grounding problem - sometimes if the RM or Chord Organ is in a separate case from the output, you need a second patch lead between the cases to make a good ground connection

Loquelic commented 6 years ago

yeah i can hear any chords when i switch on it, but any time i turn the knob or i push the green bottom i hear a blip sound. I'll take a look at the resistors ecc....

lushsounds commented 6 years ago

My problem is resolved. The SD card was previously ignored, because it wasn't formatted with the option "master boot record". Since I did that (FAT32 + master boot record), the TXT file on the SD card is taken by the module.

Thonk-Steve commented 6 years ago

Ah good news!
