Hi - I think you haven't installed the FTDI cable. You need to download and install the drivers.  Then select it in the dropdown box in Easy Uploader. You've currently got the Mac's Bluetooth port selected.

Many thanks for getting back to me. Unfortunately, it isn't powering up at so I haven't been able to upload anything so I'm not sure where to go from here:

avrdude done.  Thank you.

Hi - the Odytron Patches should be a .eep file, not .hex, so you shouldn't have been able to load this as firmware (it'll only upload .hex files, not .eep)

What happens if you upload a different firmware?  Does the software upload OK and all is back to normal? If it doesn't upload, click the "show console" box in Easy Uploader and copy and paste the text here, so I can see what happens.  thanks

Atmegatron/Odytron Hardware technical support / Atemgatron (Odytron Ed) not powering up
« Last post by gr33n on December 02, 2019, 02:16:31 PM »
I have the Atmegatron Odytron SE that suddenly won't power up. I was uploading some different software and then it seemed to lose power/lights out.

I had successfully re-installed the Odytron v1.3 software. I think I have accidentally uploaded the Odytron patches (Ody Factory.eep.hex) as software rather than via the 'load patches' option(!) - could this have messed things up?

I haven't had any problems before and am using the supplied cable, etc. but it's been a while since I uploaded different software so am worried that I might have not followed the proper procedure. Any ideas would be gratefully received! Thank you.

Atmegatron/Odytron Hardware technical support / Output Impedance - Summing 2 Atmegatrons
« Last post by rio on November 12, 2019, 10:37:32 AM »
As I am still thinking of hanging 2 Atmegatrons directly to 1 FX pedal, I wanted to ask, for example, how high the output impedance of the Atmegatron is.

Can a "T-pad attenuator" be installed in a cable as described here: https://www.rane.com/note109.html?
How high must R1, R2, R3 be calculated in order not to damage the equipment and obtain good signal quality?
The input impedance of the FX device is 1 Mohm.

Thank you and Greetings!

I also tried various other software:
* Acyclotron: rather quiet output, behaves weirdly
* Atmegadrum(s): seem to work, but output doesn't seem to be quite as loud as stock Atmegatron. Presets are - weird?

I tried to update to the Strings software today. It seemed to work fine with the Easy Uploaded, but I got almost no sound out of it - headphone output seem to work though. It also seems to sound a bit strange and quite unlike what I expected (completely different to the YouTube video).

sorry for posting this in snippets, but I still cannot get my full post through

Hi,

I'm having trouble posting here so this is a placeholder for a full post. Hopefully a minimal post will get through.
