Stuart | Aug. 8, 2022

An excellent product, easy to assemble, and VERY flexible!

For Teensy 3.2 MIDI Breakout board, 3in / 3out, USB

The big pluses: This is a AWESOME bang-for-the buck MIDI interface. MIDI 3 in x MIDI 3 out, plus USB MIDI. Very flexible routing (can be changed via programming OR by using a MIDI router app connected by USB to a computer). If you are an experienced board maker, this build is EASY. I got it done, including flashing the firmware and testing the board, in under an hour.

The down-side/challenges: The documentation is scant, and so you need to look at the board carefully, place the parts accordingly, and you're off to the races. As another reviewer mentioned, be prepared to flash the firmware for the Teensy 3.2 (not included in the kit).

Also, unless I missed something, be prepared to either design and 3D print an enclosure, or make your own box (laser-cut acrylic, perhaps?). I'm designing an enclosure to be printed in PLA.

Hi guys, I know sometimes it's not clear where to find the link to documentation on the product page. You have to click Specs and the follow to Source Code section. All files including firmware, hi res pictures, BOM and design layout for laser cut acrylic panels are placed on Github. Here is a link for your convenience: https://github.com/Deftaudio/Midi-boards/tree/master/MIDITeensy3.2

A happy customer!!!

For Eurorack Faceplate and Synth IO kit Raspberry Pi 4

The communication was great! My first raspberry pi build and the help was awesome. Fast to respond and fast shipping too!

Does exactly what it is supposed to do!

For Teensy 4.0 MIDI Breakout board, 5in / 5out, USB

It is a high-quality, well-designed board that does exactly what it is supposed to do and works well for my needs. The board shipped super fast and was complete.
As for documentation...I didn't need any, and the published schematic was all I needed to get going. I did not need to communicate so I gave a good rating for the benefit of the doubt. Thanks much!

Great super useful tool, if you can house it.

For MIDI MERGER / SPLITTER 2in->10out Thru PCB or Kit

The build documentation was great, I managed to build the splitter/merger without issue & it works great.

That said, the documentation related to getting a housing made for it left a bit to be desired. Why CorelDraw for the design file? I took the suggestion for getting a top & bottom plate made to sandwich the board with nylon standoffs. Luckily I found someone with a laser cutter able to work with the file. But since the file in the GitHub only provided the corner hole placement, and the only flat image of the board graphics is chopped off at one end getting proper cutouts for LEDs, Switches & having labels engraved proved more difficult. This resulted in just having the entire top be a framed open rectangle. Certainly sufficient for the task but a more widely used design file type with more of the board graphics would have made this less of a slog. Kit & function 10:10, getting an enclosure produced for the kit 4:10

Great clock converter

For MIDI Sync box Din Sync Any sync PCB or Kit

Was a little frustrating due to brief documentation. Had my doubts testing. But this thing is driving my KPR-77 at full speed with a MIDI clock. Highly recommended.

Jeffrey | March 13, 2022

Exactly what you'd want of a device of this type.

For Teensy 4.1 MIDI Breakout board 8in / 8out USB host

This board did exactly what I needed it to do. The example firmware was all that was needed for me to write my own and the inclusion of throughholes for the Teensy header makes this a flexible solution for those looking to push the limits of what the Teensy 4.1—and the average musician—can do with MIDI.

Thank you!

Cost-effective option for MIDI splitting

For MIDI Thru 2input -> 10out splitter PCB or a Kit

Bought this to replace my ailing MOTU MTPIII. I mounted the board to a scrap piece of 1/2" acrylic to give it some weight and keep it from shifting around. I think the board could use some support in the middle. Looking at the traces, there's definitely room to add more mounting holes.
It's easy to build and it's cheap.

Response from Deftaudio | March 9, 2022

Thank you for your review! It's a good suggestion to add a middle hole for the extra mounting. I'll certainly do this on the next batch. Great idea!

Cooper | Feb. 3, 2022

Amazing & Simple Product and Easy to Assemble Kit!

For MIDI Thru 1in -> 4out splitter PCB or a Kit

This is a very simple & affordable project that does exactly what it's supposed to do. I received it in the post relatively quickly and it was packaged up almost too nicely. :P The kit is very easy to put together and could take someone anywhere from 30 minutes to an hour depending on their experience. I did encounter some issues with the BOM (which serves as the documentation), but I was able to figure it out easily. Andrei already got back with me about it and it was a misprint of an older spreadsheet. Only thing I'd recommend changing is something to better describe how the power jumper works right on the silkscreen so there's no guessing about it... and maybe a proper USB-B connector instead of a USB to barrel cable.

Great DIY MIDI utility

For Teensy 4.0 MIDI Breakout board, 5in / 5out, USB

This is a very good and easy to construct MIDI device with many capabilities. I use it as a MIDI interface and I find it to be very useful and reliable for my needs.

Jay | Dec. 8, 2021

Excellent, effective, and easy to construct

For MIDI Thru 2input -> 10out splitter PCB or a Kit

This is an excellent MIDI utility for a great price compared to commercial MIDI splitters. It is a very simple build with clear instructions. One thing to mention if you purchase the 9V power supply version is to make sure solder a jumper at JP1 on the PCB. That was a simple mistake I made, but Deftaudio easy to communicate with and helped me figure out my error.

Mykola | Nov. 22, 2021

Useful, good quality, easy 2 assembl, shipping price offends

For MIDI Thru 1in -> 10out splitter PCB or a Kit

You better start building this very useful item from the end. Read the bottom part of the XLS file and solder resistors first then add bigger components like capacitors, dips, din ports. For resistors soldering use a fabric glove to protect fingers from the burn. Din port needs one-shots soldering, insert it to the end then solder one extreme leg, this will fix din to PCB and free your hand. Move on. The middle leg wants more heat to solder, because of its bigger mass. Solder everything and shortcut jp1 jumper 1-2 pins to always use a voltage regulator if you will use external psu. This will save you IC hex inverters, cs they work till 6v max. Check the voltage on the led socket with the power on, no more than 5+ volts. Power off and then put ICs in DIPs.
Voltage max for the light-emitting diodes like 9v, this moment missing in the manual.

Olivier | Nov. 17, 2021

GREAT!

For MIDI MERGER / SPLITTER 2in->5out Thru PCB or Kit

The kit is great, easy to achieve, works all fine.
Used into my guitar rig to merge Midi Output (giving midi tempo) and Thru of an eventide to the other FX procs.
The only this I'd suggest would be to modify the PSU input with Negative on center and positive outside like most of the guitar pedals of the industry.

Easy to build, extremely useful

For MIDI Thru 2input -> 10out splitter PCB or a Kit

Was a simple kit to build, and I'm far from an expert. One of the optocouplers ended up being bad, but that could have been my fault. I had spares on hand, so no problem. Love the design, very elegant!

Peter | Sept. 7, 2021

Nice little project

For MIDI Thru 1in -> 4out splitter PCB or a Kit

I put this together without too much drama. but i do have electronics experience - Other reviewers have stated trouble with component identification and orientation. I was familiar with these issues and just had to double check - anyway, I plugged it in and it worked 1st time - didnt have to troubleshoot. So I now have to think about what sort of enclosure I want to put it in.
Cheers to Deft audio.

A high quality DIY Eurorack Midi Thru kit in just 2hp! WOW!

For Eurorack MIDI TRS Thru 1in -> 4out midithru

The PCB board is clearly laid out, all components were included in the kit (and the shop meticulously checked off each component in the provided documentation).
High quality silk screen on the PCB and the PCB based faceplate of the eurorack TRS Thru module.
The documentation is fantastic, schematics are included, hi-res detailed images, the BOM, its all available and clearly organized on GitHub.
It took me about 2 hours to solder and put together the kit. Make sure to use flux!

If I had any recommendation for an improvement, it would be for the shop to use an aluminum face plate rather than a PCB one, as PCB ones have a little bit of flex. Although in my case this is not an issue, as normally I don't usually switch out the MIDI out cables from my eurorack kit.

I highly recommend this shop, and this product! Its high quality, quickly shipped, and the proprietor answers messages quickly!

Satisfied with the midi merger, a great buy

For MIDI MERGER / SPLITTER 2in->10out Thru PCB or Kit

The kit is easy to assemble and the instructions are clear. With a minimum experience in electronic assemblies it is completed successfully. It works perfectly and exceeds my performance expectations. Excellent

John | May 13, 2021

Awesome as always!

For MIDI MERGER / SPLITTER 2in->5out Thru PCB or Kit

This is an excellent expansion board! Again as in another product review, this works with some of the most expensive midi controlled Audio gear (that claim you have to use their splitters/boards/pedals only (maybe for warranty but not for operation).

There is just something good to be said about better, non proprietary, fair and lower priced equipment!

John | May 13, 2021

Can I say enough? Excelent product

For MacroPot deeply programmable MIDI controller Kit

I will be buying more of these. I am using them for MIDI interface on Guitar Rigs and Audio equipment. This has interfaced well with everything I have tried.
I, myself, helped write some of the Midi code back in the late 70's what I would have given for something like this back then!

Deft audio has an awesome non proprietary system that works well even when interfacing WAY More expensive proprietary systems.

The online videos are excellent for the visually inclined and the printed instructions are easy and accurate. Make sure you read carefully this is electronics after all!

Some have claimed they have trouble contacting DeftAudio. I have had no trouble at all! And they have been exceedingly helpful.

Simple, Cheap and Works

For MIDI Thru 1in -> 4out splitter PCB or a Kit

This MIDI Thru 1in4 does the job well. I'm not a musician so I can't comment on fidelity, or on longevity, but it works for me just great and don't notice any flaws. The build itself was easy. I appreciate that and it's very low cost, making it easily attainable on a budget.

I have a beatstep pro as a master to the MIDI 1in4, then 4 Thru to 4 other Arturia gear, with sequencers, and a TD-03. I set sync to midi on all devices except the BSP (Int), which allows me to start/stop all other devices, but still control each device's sounds independently. Or change sync and control most everything from the BSP. The 1in4 made this all very easy. I was nervous at first, because I had read of a few issues with getting things synced, but I had no issues and I'm pretty stupid when it comes to music, much less MIDI (I get the gist lol).

Ronald | April 15, 2021

Excellent easy project.

For MIDI Thru 1in -> 4out splitter PCB or a Kit

High quality board, helpful documentation. Had this put together and running in my rig in less than 30 minutes!

Roberto | April 5, 2021

very good product

For MIDI Thru 1in -> 10out splitter PCB or a Kit

Very good product. i connect my midi keyboard to control a pro-1, system1, ms20, neutron, crave, skulpt and other synths

James | Feb. 16, 2021

Excellent product, works as expected, very affordable

For MIDI Thru 1in -> 10out splitter PCB or a Kit

Very happy with this purchase, I ran into an assembly issue (soldered a component backwards) and Andrei was very responsive and helpful. The product itself is well designed and works as expected. A++

Marco | Feb. 12, 2021

Ok, could be better.

For Teensy 4.0 MIDI Breakout board, 5in / 5out, USB

Board ist ok. I modified the Board to comply to the Midi Standard and to be more robust. Used the Board to build my own Midi Interface with Midi merge and several routing options. I added some 5V Open drain Output Logic drivers because to Connect the Controller Pins directly to the connector ist not a good Idea. Added also some components for better EMI. The input optocouplers are not the fastest there are better newer replacements. Added a pull down to the Base of the 2nd Darlington Transistor for faster switching.

Robert | Feb. 11, 2021

Up and running!

For Teensy 4.0 MIDI Breakout board, 5in / 5out, USB

Thanks for this!

Delivery was quick, packaging was good.

The design is thoughtful, clean, and will generalize to any number of applications.

Assembly was very simple and straightforward. Had it completed the afternoon I received it.
I was able to get the demo code provided on github running right away. No hassle.
(note: I have some experience with both PCB assembly and with Arduino/microcontroller devices)

I don't have an opinion on documentation as I didn't actually look for any...
Same with communication -- I did not have to reach out for guidance, assistance, or other information.
I am leaving these fields at 5 stars because they were effectively non-issues, and this is very good, imo.

Would have happily purchased the acrylic panel covers had they been available.
Will happily purchase other items from Deftaudio in the future.

Keith | Feb. 3, 2021

Excellent all round

For MIDI MERGER / SPLITTER 2in->10out Thru PCB or Kit

Item selection and purchase was clear and easy. Just works! Andrei communicated excellently and the shipping/tracking was faultless. Well done and thank you :)

Jason | Jan. 24, 2021

Love it!

For MIDI Thru 2input -> 10out splitter PCB or a Kit

Wanted to upgrade after using a 5 in 1 splitter for the longest time. This kit is great, priced right as well. I swap between my deluge and my midi keyboard controlling my synths with the switches, it's seriously a great kit!

Jason | Jan. 18, 2021

Straight forward, easy to use

For Teensy 4.0 MIDI Breakout board, 5in / 5out, USB

I was looking for a Midi 'router' that I could program myself. I needed more control than a typical setup due using both proprietary and General Midi data. This did the trick, much appreciated!

Dmitri | Jan. 8, 2021

It was fun!!!

For MIDI Thru 1in -> 4out splitter PCB or a Kit

It was fun(to build)
The only sad think that I was over with it in 10-15 minutes. (Very simple kit)
Tested, works great. I have few synths that that don't have midi thru/out... This solved the problem perfectly.
Fast shipping (to Canada) ThankQ

Jacco | Jan. 3, 2021

Great product, excellent quality

For MIDI Thru 1in -> 10out splitter PCB or a Kit

This was a fairly easy build. The build took somewhere about an hour, including my son soldering the DIN sockets. The only mistake I make by not reading the minor instructions was mounting the leds the wrong way. I mounted the board in an wooden stand that houses 8 Roland Boutique units, no cable mess anymore now.

Howard | Nov. 22, 2020

I am sure it's a good product, if you can get through...

For MIDI MERGER / SPLITTER 2in->5out Thru PCB or Kit

I am sure it's a good product, I ordered two kits, some of the IC's from the first kit didn't work, so I took chips from the second kit, I got it to work for a short time, but it eventually quit working. The main problem/gripe is that the tinde website wouldn't allow me to contact the seller "privilege restricted". So, if you are kinda new to DIY and might need tech support, I would suggest you go somewhere else, if you are more advanced and can trouble shoot go for it!!!

Response from Deftaudio | Nov. 22, 2020

Hi Howard, there are absolutely no restrictions contacting me for the support. You're welcome to contact using Tindie (if it's a problem, then get support involved) or Github (where all schematics or source codes) or even a Youtube page (where tutorial videos are). Let me know the problem and how I can help.

Daniel | Nov. 15, 2020

Useless if not working

For MIDI Thru 2input -> 10out splitter PCB or a Kit

The board is not working. No instructions although it was easy to follow the photos online. No communication with the seller. Techy jargon I'm trying to follow just to pursue something creative otherwise.
