There's only one - it sounds cool, but it's really fragile and hard to play! I've learned a lot since then and would love to make a version 2 at some point, but probably using an existing guitar as a starting point :)

ok thanks@@BradshawInstruments

So, the only built-in method of sync (without doing any coding/hacking/mods) is via MIDI, which Drumkid can send or receive, but I believe Pocket Operators use simple 5V pulses instead, which probably means there's no direct way to sync the two without involving another piece of gear somehow. However, if you don't mind a bit of hacking (which I'm guessing since you've figured out which pin the tap tempo button is connected to!), it should be totally possible. You could look for the line "Serial.write(0xF8)" (MIDI clock output) and output a 5V pulse on D10 at the same time, which would make Drumkid the master. You could also look for the line "else if(thisMidiByte==0xF8)", which is where the code reads an incoming MIDI clock signal, and try and replicate what happens there but in response to an input signal on D10, but this might be a bit more complex because you'd also have to remove the tap tempo button code etc. If you're not fussed about MIDI at all, I think you could even disable the serial read/write and use the MIDI ports to send/receive simple sync data. Hope this wasn't too overwhelming a reply!! Let me know if you need more info.

Thanks for the comprehensive reply! I am really not a coder so think it would be easier to use a korg volca to accept midi clock in (from drumkid) & output pulse for po...

@@BradshawInstruments Wow good for you buddy of course little ones are the priority! Thanks for the detailed reply I'll wait for some uptade! 👍👍

Hi, I use version 1.8.19 at the moment, so I'd start with that.

@@BradshawInstruments on your github page last version is 1.2?

@@BradshawInstruments hello, I can't download ur github code, there's no green download button

@@ckngmad1357 On GitHub, click the green "code" button, then "download zip"

@@BradshawInstruments okey, thank you sir

Thanks! Yeah, it's definitely the most-requested feature and is top of the list for version two, whenever that happens. Have got a prototype in the works with higher-quality audio, sync in/out, and a more robust case (as well as a Eurorack version), but kids are taking up a lot of my time right now, so it won't be until maybe summer 2023. Keep an eye on this channel or my mailing list for news :)

@@BradshawInstruments totally get the ‘kids’ and they def deserve the time. I’ll also ask for one thing to not lose, normal 5-pin MIDI. This would be an awesome complement to my Sequential Circuits Tom to allow some ad-lib variations.

Yes, you can do this via MIDI. Sorry for slow reply!

Hi! This usually just means the batteries don't have enough power. Maybe try some new batteries or try powering with a USB cable? If that doesn't work, let me know (my email address is included in the box!) and we'll try and figure out what's happening.

@@BradshawInstruments new batteries fixed it immediatly! hahaha Thanks for replying so fast :)

A lot of stuff would or could work, like ipa or maybe lighter fluid. It removes stuff like corrosion or other grime that could be screwing up the connection it makes when the metal makes contact.

It's a paper towel not a napkin. Kitchen roll = paper towel

Thanks! 😃 It can do MIDI sync, so yeah that should be fine
