Necro reply for sure, but the Toshiba Satellite 4010CDT has the Yamaha OPL3-SA3 inside it.
Only works properly if you install drivers from Yamaha though, the standard Microsoft SAX driver only works for MIDI file playback.
I grabbed drivers at the bottom of this page: https://web.archive.org/web/20160307174 … /download/
"OPL3-SAx Drivers for YMF701, 711, 715, 718, 719"
Did you test the pins of the pot to make sure your wired it to the correct pins? Did you wire the negative or the positive to the pot?
The trimmer (pot) is on the GBA's main board, hopefully nanode didn't solder anything to it - you don't need to for this mod.
The trimmer is just used to control the signal level to the LCD screen I believe.
Does the trimmer (pot) stop turning at some point or does it turn forever?
If it turns forever it's probably broken from excessive force.
The pic you posted up looks like it does only just need some adjustment with that trimmer for sure. It's the same dim colours I got when I installed my AGS-101 screen.
With the 40-pin adapter cable you should solder a wire from one of the pads on the adapter cable to a point on the GBA's main board.
Grab the instructions PDF from this Gist and double check.
The Gist says you may need to solder a cable to ground to avoid washed out colours.
Good luck!
A modified 4 player cable works, made one myself for MIDI syncing more than one nanoloop.
Just solder all the IN lines together ;)
Well, I updated my OP-1 to the 2016 Beta OS to check out the PO sync and it works (if you double the tempo output)!

And actually building a half clock to full clock converter wouldn't be too bad.
But I think the best way is to just build one of these and include the USB Host shield: http://gieskes.nl/master-clock-generator/
Avoids drift and it's a cool project. I'll probably build one in the next couple weeks.
Nope, nanoloop only supports half-speed sync as master (according to the manual anyway, I haven't tried nanoloop as slave!).
If only the OP-1 supported sync *input*.. it's got the mic input, I don't see how it couldn't be implemented!
Urgh, whyyyyyyyyyy :(
Nice one!
Apparently, the new beta OP-1 OS supports pocket operator sync via the headphone out (sync pulse goes to tip of plug). Unfortunately though, it's that silly half-step sync scheme (seriously why did anyone ever think this was a good idea)..
No, that's really great! That means the OP-1 could be master for nanoloop as it supports analog sync and works with the POs!! This is great news - looking forward to that release. Woo!
So, I did it... almost.

Code here: https://github.com/2xAA/MIDI-Clock-Convert
There is a pretty significant drift on any BPM over 120 though, I'm not sure if that's nanoloop's fault or the OP-1's. Could be my code but there's not an awful lot going on to slow any transmission of the clock.
I'm probably gonna put my money on it being nanoloop 2 as it doesn't have the best clock in the world. (I've had to USB-MIDI sync my recordings from it before just so when editing I don't have a huge drift to deal with)
Anyway, that's it pretty much.
I had to use an Arduino MEGA in the end as for some reason using the default Serial and the USB Host shield is a no-go, so I used Serial2 on the MEGA instead.
Thanks to catskull for advice and encouragement :)

Thanks for doing all this work Sam..! I hope you get some positive results soon so that the rest of us may benefit, too
No worries, I hope I get it done too haha. Really want this to work, I have plans.
Also, I hope oliver saw my post's edit.
I've got nothing working regarding MIDI clock with nanoloop 2 (using the sync cable, not the adapter of course).
Hey!
Just bumping this as I've been working on something to sync nanoloop 2 as master to the OP-1 as slave using Arduino and the Circuits@Home USB Host Shield.
Teenage Engineering's website seems to be wrong where they say the OP-1 will sync with MTC, the OP-1 will actually sync externally to MIDI Clock only (as far as I've seen in my tests anyway).
This means tempo syncing nanoloop 2 and the OP-1 becomes very straight forward, apart from one problem I'm running into - I can't get an Arduino to read nanoloop 2's MIDI clock output, the Serial.read() call just returns nothing from the link port when using littlescale's Arduino sketch, which works fine with other MIDI clock sources I've tested.
If anybody has any suggestions or information regarding how I'd get an Arduino to read nanoloop 2's MIDI clock output I'd very much appreciate it.
Cheers.
edit: it seems that nanoloop 2 doesn't respond to MIDI clock when in 'M' sync mode, maybe MIDI clock sync is currently broken?

Has anybody tried this with a 32M?
I seem to be having major issues with it.
Chord just crashes with a hella glitchy screen when I try and load it up.
Might be a dodgy 32M cart though, will test with my other 32M and post back.
EDIT:
Okay, on my other 32M I get a glitched up screen too.
The only thing I can think it to be is not being able to clear the SRAM from LSDJ being on there?
LSDJ uses 128K and Chord uses 32K - so maybe it's something to do with that.
I know it'll be difficult for most people to test as the Transferrer II units are fairly rare now, but if the dev wants to try and solve this issue I'd be more than willing to flash ROMs and report back.

No. That dicussion was the problem of making an SD cartridge with no battery, or fitting everything on the cartridge. EDGB does have a battery, so that's not a concern. The problem here is how much SRAM space the cartridge is assigning to the running ROM. Currently it can assign at most 32 kB. The SRAM chip in the cartridge is 128 kB big, but half of that is reserved for system data. This means the biggest size SRAM LSDj could use is 64 kB. This is ok. It's enough for a couple of saved songs. But this would most likely require a firmware upgrade/modification for EDGB, which I'm hoping to be able to do.
64 kB is the same the white Nintendo Power cartridges expose to a program like LSDj. Incidentally, they also have a 128 kB chip which may be possible to unlock, but that's a story for another day.
Did you need an Everdrive GB to test with?
I have one I'd like to donate to your cause - would be fantastic to get it working with LSDj.
Edit: I tried LittleFM 0.5 and it complains it doesn't have 128kB of memory, so it looks like the Everdrive is eating up enough for LittleFM to freak out about and LSDj to only allow you to reset the SRAM?
Idk what I'm on about, but hopefully that's a good start to solving this problem.
Just gonna drop the yearly Merry Chipmas here.

Sure? Or any of the free services out there. Though I suspect ucollective will end up having the same issues when the data size is too large for cheap services- or when the cheaper services bottleneck.
Just saw this on my monthly cm.o visit 
I'm actually going to do incremental backups. Select tracks by date from the database and backup those uploaded in the specified timeframe.
I have unlimited storage at a fixed price, so I'm not worried about running out of space, but I do want to move to S3 and buy a small dedicated because at the moment I have jailed shell access (which royally sucks).
Anyway, might be something to think about Mr 80.
