Mini MIDI Keyboard

I’d like to apologize to all the admins here for making this the unofficial Pocket Midi comms center, but it all started here, so this is kinda where it lives :innocent:

Regarding:

The first batch of 50 had some pent-up demand(after 2 yrs of promises), but after all the sales, it looks like about 25% of those who signed up or showed interest actually bought one. This tells me that I’ll need a similar number of 200 to justify building another batch of 50. I plan on adding some kind of interest meter on the PM site in the near future and will announce it here when it’s up.

NO SOLICITING! PEDDLE YOUR WARES ELSEWHERE GUY! Just kidding, I’m pretty sure we’re all friends here. Except maybe that one guy.

Well Sean, most people that come up with an idea like this don’t pull it off. I for one remember when Aisjam made his video on your keyboard thinking to myself “yeah that’s never going to be available to us peasants”.

And then when the user alexandrosroussos made the wish for a metal tracker mini I actively said “that’s never going to happen.”

And now here we are, we have flying cars, metal trackers, and magical little keyboards that snuggle up to them. I’ve never been happier to be proven wrong.

The last two years were probably the roughest of my life, which feels weird to type considering how screwed up covid was. So personally I totally forgot until I finally paid off my anniversary edition tracker last night and though to myself , well wait a minute, what about that amazing device that may or may not have happened. So I’d be curious of how many minis are out there and try to get some videos and pics out there because I imagine a good amount of owners either forgot, have no idea it actually happened, or it just wasn’t the right moment to buy something right then. I do know that if there aren’t any available they won’t sell, and all lot of people have short attention spans and may not think of the cool thing that wasn’t available that one time. I’m probably going to forget again for a couple of months since it wasn’t available.

I don’t know if anyone is familiar with the MicroMonsta. I was on the wait-list for a year and a half for that thing and totally forgot until I got the email and almost couldn’t come up with the money in the allotted time to place my order.

I guess what I’m getting at is that you made a winning product for a niche item. I’m sure if you make them they will sell, it may just not happen overnight or even within a year or two. Sell them at a price that makes it worth having them around. Or just make me one for my birthday and I’ll shut up.

Just keep being awesome, that’s what matters.

It’s my birthday everyone!!! Someone send me a keyboard!

:onfire: I am super exited to announce that the bluetooth Configurator web app is up and running - Now the KB1 can really shine! It is designed for mobile, but runs in any browser that supports bluetooth (Safari :sad_but_relieved_face: ) I have had good luck with Bluefy V Browser https://vbrowser.co (a good ios browser that supports BLE) on iPhone, chrome on android, and chrome on desktop (other browsers up to y’all to try). To use this with your KB1, you’ll need go to the GitHub repo and follow the instructions in the readme to update your firmware to v1.1.1(back up first of course ).

web app is here - KB1 config

get firmware here (in releases) - GitHub - PocketMidi/KB1: Open-source MIDI keyboard controller with built-in speakers that transforms the Polyend Tracker Mini into a complete portable music production setup. Includes hardware schematics and ESP32-based firmware.

software info guide here - GitHub - PocketMidi/KB1-config: KB1 Config lets you wirelessly configure KB1 over Bluetooth. Map MIDI CCs, manage device settings, and use live sliders directly from the browser.

There will most likely be bugs to kill, but it’s working great for me so far; report any issues on GitHub.

Received mine this morning, spent all day jamming and having an absolute blast. Extremely happy with it, and I wanted to say thank you for the time and effort that was put into this project. Been a wild ride watching this thread. :slight_smile:

I poked around with ESPConnect for a few minutes after reading the instructions on github and watching the video tutorial, gonna find the courage to click the ‘flash’ button tomorrow to update the firmware. Just to confirm: is there an offset needed for the flash? Does it need to be pointed at a certain partition? Is it smarter than me and knows where to flash? Thanks in advance. :slight_smile:

In case anyone else has questions, I have updated the readme on the KB1 github page GitHub - PocketMidi/KB1: Open-source MIDI keyboard controller with built-in speakers that transforms the Polyend Tracker Mini into a complete portable music production setup. Includes hardware schematics and ESP32-based firmware. with a more detailed Quick start guide and instructions on using ESPConnect,

What is the intended functionality of the “flash offset”? I am genuinely curious!

The KB1 uses an ESP32-S3 development board at its heart.

There are lots of other flavors of ESP32 out there.

The .bin file (firmware) is actually a merged file with 3 parts, and depending on the chip variant, the order in which they are mapped to the memory is different.

ESP32-S3

0x0000 → Bootloader

0x8000 → Partition Table

0x10000 → Application Firmware

classic ESP32 chips

0x1000 → Bootloader (different offset!)

0x8000 → Partition Table

0x10000 → Application Firmware

The brilliant new ESPConnect app gives options, but greatly simplifies the whole process.

Before that web app was created, the whole flashing operation was overly complicated and a real pain to set up, so this guy really deserves some coffees -

Flash went perfectly. :slight_smile:

Thanks for the updated instructions and ESP32 rundown, this is my first exposure to the platform. Didn’t want to brick the thing on day one. :sweat_smile:

Well, now I know how to set alerts on here. Wish I knew that a month or two ago.

It was a long journey but finally you are mine now.

It’s even cooler than I imagined.

I hope some of you have had a chance to try the new Configurator web app. I believe it will open the door to many more hours of fun with the Polyend Tracker Mini.
I do want to let everyone know that since it is still a new system(KB1 + Config app) to please keep checking back in the GitHub repo every now and then, since I’ve been updating incremental firmware versions as I find issues or bugs. So if you have any weird glitches, look there first, and get the latest build.

And also, if anyone doesn’t want their KB1, I do. It’s still officially my birthday for the rest of the year, so don’t be shy :wink:

There have been a few requests as to when the next batch will be ready, and I keep saying I’m not sure if there’s enough demand.

SO if you want one, head on over to the website https://pocketmidi.com and let me know. There’s an interest meter there now so we can all see the demand. The only requirement is that you must log in as a user to vote, so I can get a real email for everyone.

Also newly added up top is a version display, so you all know at a glance the current firmware/software versions.
