MIDI to G-Code
-
suppose the specific midi file for comparison would be good, almost feels like there are gaps here and there.
come think if it midi would allow chords (or whatever they call "parallell" notes), the duet would struggle replicating that and the conversion would have to make compromises

Midi file is here: http://www.mariopiano.com/midi-sound-file-overworld-main-theme.html
I selected the track 2. The thing is it works fine when previewed in the web tool; I guess it reads the gcode, and not the midi, as you can only preview after generating the file...
-
I've previously only tested shorter sequences, maybe 8-10 lines and the duet 2 with paneldue was always working, while the duet 3 with dwc skipped a lot of them.
I'll poke the midi file when i'm bored and compare it.
-
i'm no beethoven but can't detect any difference between the streamable video and previewing track2 in the web tool (admittedly i cut the video short, but )
-
Yes, the preview in the webtool is OK; but once uploaded on the Duet, the music is not OK anymore... The

play this side by side the preview and see if you can tell a difference? i didn't go to the step of making videos of both to sync the audio to say left and right. in any case it was mostly meant as a "this is what is sounds like on my paneldue"
-
It seems to works fine on your Duet; I can ear missing notes in this small part, on mine... I'll dig further tomorrow to see what notes make problems.
Thanks.
-
no worries, it shouldn't make a difference but it was an 7i pandeldue (with a slightly MacGyver fix on the buzzer. can try an older regular 4.3 later, but with the same firmware i expect them to do the same thing.

I just tested your mario code on my older V2 PanelDue and it ran fine. I couldn't get it to play over DWC and can't disconnect the PanelDue without some dissaembly.
Here's another version of the mario theme that's even faster that plays perfectly as well.
-
This file has even more missing notes... Looks like a com issue between the Duet and the PanelDue, don't you think? Is there a checksum used for this com? Some commands seem to be drop...

there is, could be a possible factor. shorter cable or lower baud rate are simple tests. i used the supplied 1 meter or so cable for the 7i test (i did twist the pairs a little just to tidy it up a little)
also took a stab at recording the preview but computer failed badly at recording its own audio (at least using the win10/xbox game thing)
-
@fma Can you provide a video of how it's playing on your end?
I am also using the 4 wire cable. It's about 1.2 to 1.5 meter long and I've braided the wires as it runs alongside some motor wiring.
-
Ok, I'll do that. My cable is 1m long, and I also twisted the wires. I will try to use a shielded cable.

trying lower baud rate may be simpler as a test?
-
How do I do that?

-
It does not seem to work: as soon as I change the baudrate, the PanelDue is unable to communicate with the Duet...
-
Did you change the baud rate at the PanelDue to match?
-
No :o/
Now it communicates, but it still misses notes. I only tried at 9600bauds; I will try other speeds tomorrow.

if it stayed the same, no need to try other speeds, but if it missed more notes it might be too slow.
