MIDI to G-Code
-
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.
