edit - this was not the answer!

but I think the answers to 1 is "yes" and 2 is "there are two channels", so two mono or one stereo?
You could of course combine samples to have them play as one sound.

There might be some useful titbits in here/he might be a good person to try and talk to?

Well, I never got that working but I found a half finished old Arduinoboy, fixed it up and that now works. Not really sure why that works and the teensy boy didn't, but at least it's synched up.

Thanks for all the suggestions!

a is for an incoming analog click to set the timing of the sync and after that is m which is midi out as master. what devices are you trying to slave to your nanoloop? ive had trouble getting my built midi cable to start my digitakt, but works on my tb03. so i just route my tb’s midi out to my digitakt and that works out well.

thanks - yeah it's a Digitakt and ableton through a MIDI interface I can't get to start, so maybe the Digitakt is just a no go because of the voltage.

The annoying thing is that I also can't get the teensyboy to work in nanoloop mode, when I know this is working for someone else..... I might have to have another go at getting an arduinboy I built going and see if that is any more use.

alas this did not solve things.
I have two GBAs, a teensy boy and a newly modified cable and I get absolutely no effect from any of it. Weird.

whoa, that is cool!

thanks, that sounds like a very good idea! Will give it a try later.

having massive issues getting Nanoloop to sync to anything at all tbh- now trying with an arduinoboy with a similar lack of success!

possibly my drum machine wants 5v i guess. no idea whats up with the arduinoboy though

I can't seem to get this to work with a home made MIDI cable. I have it wired up as below, and have checked with multimeter.... seems to have zero effect on anything whether I plug it into my audio interface and try and sync ableton OR into my drum machine.....

I wondered if it might be this:

"The current supplied by the GBA's link port does not quite match the MIDI specification (3.5 mA instead of 5 mA). So far, it worked with all devices tested but there may be devices that require full 5 mA."

but seems odd that I should own two things that object to the voltage when it sounds like it's uncommon.

Has anyone had issues getting this to work/could explain more clearly than the manual does how I am supposed to set off nanoloop so it should work?

I'm in the middle of building an arduinoboy to get round this (at least until I can get a USB midi dongle) but would be even better to only have to carry a MIDI cable with me if I could get

maybe you might have luck inserting another/different clock across X1/X2 too?

a la:


(or maybe you'll have luck making magic smoke!)

oh. sorry, somehow missed the other post saying the same thing!

Hi - the datasheet for that IC is online here;

https://www.datasheetarchive.com/pdf/do … erm=HT3494

it says it is clocked by a crystal oscillator in the chip, so (I think) there won't be a pitch bend in the way you're expecting.

Maybe you can work something else by starving it of voltage or something.

also, if you need more buttons than you have pins, it's super easy to use multiplexer chips to have one pin read loads of signals.

Teensy is a bit more set up to use MIDI off the bat, and there's a really simple guide to using multiplexer chips halfway down this page:


the controller I shared above is running all those buttons/sliders and faders from one Teensy (and a lot of multiplexers)
