Tindie

Works exactly as advertised, no problems so far. The built in clock is nice and is the reason I bought this, rather than the Banana Split from same seller. Easy to use and set up. I needed something to sync a few synths to a MIDI clock and play multiple of them at the same time, so it does pretty much everything I needed in a small cheap package.

I'm a little worried about the lack of casing (might want to use it live at some point, as it is it's more of a plug-in-and-leave-in-its-place kind of thing) and would have been glad to pay extra for a small BPM display. It's cheap though, so I can probably buy/build a BPM display and some kind of casing and still pay less in total than a dedicated MIDI clock would have cost me, let alone a clock + MIDI splitter.

All in all, pretty great.

Works perfectly

Got my banana split on time after prompt shipmnent. It works nicely, and the good thing is that it is smaller than what I thought! not much bigger than a USB hub. The only tidbit is that it need its own power supply. But does the job it has to do nicely.

Daniel | Jan. 9, 2017

Great gadget!

This is just what I needed! Now I can connect a bunch of synths with no need for complicated and unreliable midi thru chains. Works perfectly in this capacity. Hasn't missed a beat so far.

I've not tried using the kit as a metronome yet, but I expect it'll work as flawlessly as the other mode.

Michael | Dec. 28, 2016

It works!

Very cool. Works like you'd want it to. Great price point relative to the cost of other midi clocks starting at $500+.
Bottom line. It works....and has lots to cool flashing lights.
Would have awarded 5 stars but for lack of numerical bpm readout.

It arrived, and it works

For CV.OCD - A super flexible MIDI to CV box

Great device! But mine has arrived without one of the leds. However it works fine.
The missing led makes a bit dificult configure that option because the leds in the options menu are the only visual feedback midi hub provides.
Seller is sending me some extra leds 4 free, he also ofered me repair it himself. So I would recomend this seller anyone. Great customer support!

Gulp! sorry about that, do you want to contact me directly?

David | Nov. 25, 2016

extremely good MIDI-CV conversion for cheap!

It's a neat little box, very configurable, very handy form factor (0hp and uses standard guitar pedal power). I can interface my DAW with my modular so much better than with my MicroBrute alone; it works perfectly and is a great value. Highly recommended

While there hasn't been a problem yet, I am a little concerned about the durability of the jacks -- they are directly mounted to the circuit board apparently, without nuts securing them to the front panel, and patch cords don't click solidly into place. I take a little extra care when patching it and don't really expect any problems though.

As with many small electronic devices, I do wish it had a power switch -- but as the control center for a modular system, it's not like unplugging another cable is a big hardship.

Amazing utility !

For CV.OCD - A super flexible MIDI to CV box

It does the job well, leaves space in the rack, and is configurable in pretty much any way you may desire.
The power supply is the same as a guitar pedal so if you already have a pedalbay around your modular it becomes a killer choice.

Don't have much more to say then, Hotchk155's designs are dope as always... :D

James | Oct. 10, 2016

You need a MIDI splitter? This is a dang MIDI splitter.

Works exactly as advertised, no audible latency, seems like a robust design. The only* shortcoming is that it cannot be powered via MIDI bus the way the Quadra Thru can, but it's got two extra ports which certainly makes up for the hassle of dealing with yet another power supply. Currently using it with a Yamaha RM1x to drive a few Volcas and it's working like a charm.

*like another user here, I just discovered that this device doesn't provide MIDI power on its outputs, which is pretty absurd given that it requires a power supply. If you have any MIDI utility stuff that needs power, you can chain it off another machine, but it would be really nice if you didn't need to keep using Thru ports on your synths after, like, buying a brick full of Thru ports.

Response from Sixty Four Pixels | Nov. 28, 2016

Thanks for the feedback on MIDI power on the outputs. I had a few queries on this and will address it in a future update, but there is a simple mod which can add MIDI output power if you are happy to get out the soldering iron... http://six4pix.com/split/midipowermod.html

Good stuff

For LE STRUM - MIDI Strummed Chord Controller DIY KIT

The Banana Split works perfectly, and it looks much cooler than the competition.

Fast shipping, low price, and a great product.
Can't ask for more than that.

EDIT: It does NOT supply MIDI power, as I just discovered, sigh. :(
Removing one product star for that.

Simon | Aug. 22, 2016

Cool Product I Liked It

Enjoyed the product the time i've had to use it.

I think i would get more out of it if the documentation was more helpful and maybe the power of some more videos would definitely do justice.

The position of the battery could be improved. Nevertheless a happy purchase ☺

Nice little tool, unique and fun

For Relay Switcher : 8 Channel MIDI-to-relay module

Most Synths have some form of an arpeggiator. But to have one in a standalone device has its advantages - no more digging through menus, adapting to that "special" style of arpeggiator on every single synth, and no more need for a computer.

This little thingy is easy to build, the instructions are mostly clear and easy to follow and it is fun to use.

Mathieu | July 15, 2016

a great MIDI object....

Thank you for the excellent midi to relay, shipping fast, low cost and efficient :-)
my Mesa Boogie Quad Preamp is now MIDI.......great

Useful and fun.

For LE STRUM - MIDI Strummed Chord Controller DIY KIT

I have now owned the "Midihub 6 way midi thru and metronome module" for just over a year. This is a great little unit. I was like many looking for a MIDI Thru unit and came across this product on You tube and though I would investigate. Price competitive and the thing looks so cute and different. Having built my set up to run without being connected to the computer I could see the advantages of the Midi beat clock. Being able to set the tempo, start and stop of all my synths, sequencers and drum machines and not daisy chaining all my devices, with the push of a button and with out a computer and DAW, happy days. Having several configurations/ options it has got me through a few problems in various set-ups. Well I came to the site not knowing I needed the "midihub 6-way MIDI Thru and Metronome Module" and now it's a permanent device in my set up, whether I'm using the computer or not.

Tim | April 30, 2016

Crackin' piece of kit. Excellent work sir.

Straightforward build, great fun to use.

Docs were excellent, only (very) minor criticism is that they say the build guide etc is on Github, but it isn't -- Github has a _link_ to the docs site. Sure, clicking through isn't any effort, but if the github account disappeared for whatever reason, I wouldn't be able to find the docs (they also aren't easily findable via google).

Some standard add-ons (as separate products) might be a good addition also, like a standard case, or a larger strum board. I would guess most people would plump for a standard case (myself included), for example, rather than building their own.

Vincent | April 10, 2016

Midi splitter

This splitter is very usefull and I think it is the only modèle available with such number of outputs.
I use it to control korg volcas series ( keys, beats, etc...) And other synths.

It is well built And seems to last long.
Design is very cool by the way :)

Also the fact that it can receive any power from 9 to 12v, in any polarity is real plus !

Shipping was good, delay as expected. The maker was kind to reply my email, no bad surprises. (Ship to France)

I recommend !

Graham | April 4, 2016

Great gadget but check external clock requirements

Built this in a couple of hours - build instructions are excellent. the Arpie worked perfectly except for the external clock which although the clock led pulsed happily and F8 midi clock messages were being received the arpie would not recognize it and was silent when trying to use it.
I finally found that in order to get this to work the Arpie needs a midi Start (FA) message or a continue(FB) message then it works a treat.
(A midi stop (FC) also stops it)

Response from Sixty Four Pixels | April 4, 2016

Ah, thanks for that feedback! I'll have a think about how that could be improved... Cheers/Jason

Gabriel | March 22, 2016

Great product and great persons behind the product.

You know, one never really thinks the need a MIDI hub... well it is not your first thought anyway. Now that I have this hub, I can safely say how cool it is and a wonderful utility. Love it!

Nick | March 4, 2016

awesome hardware arpeggiator

For LE STRUM - MIDI Strummed Chord Controller DIY KIT

This is my first soldering project. After a couple hiccups and some helpful advice from Jason, this thing is fully integrated into my live rig. I am using to to control a Moog Minitaur and a Roland JP-08 interfaced by a MOTU MIDI Timepiece AV and clocked via a Korg EMX. I did find that the random mode (the mode I most often use) wasn't quite random enough. It would repeat the same random sequence over and over again. However due to the open-source nature of the kit, a couple lines in the code fixed that right up, and now it's fully random. Great piece of equipment!

Graham | Feb. 16, 2016

Yes! Very pleased!

This is easy to build and amazing fun to play with. Get one now. NOW! My neighbours are under the impression I'm now amazing at keyboards and yours can too. Now.

Mark | Jan. 28, 2016

Great Product. I will buy more.

For Relay Switcher : 8 Channel MIDI-to-relay module

I purchased this product to reroute signals in my guitar processing rack. Using a Gordius Little Giant foot controller, I can change the state of any/all relays with a single footswitch press. This product is by far the most cost effective means of accomplishing the required task.

I encountered my only difficulty when trying to use the Little Giant to program the relay configuration in programming mode. The documentation presents the midi data for configuration in hex. After some experimentation, monitoring the output of the java app in Midiox, I was able to determine that the configuration data consists of simple control change commands that many midi controllers can send.

I assembled the following chart, and present it here in case it can be of help to others such as myself.

Set relay to respond on a specific MIDI channel
CC# Value Comments
99 0 to 7 Selects which port (relay) to configure. Value ranges from 0 (port a) to 7 (port h).
98 1 Value of 1 selects the channel number parameter as the one to be configured.
06 0 Value will always be zero when configuring the channel number parameter.
38 0 to 15 Sets the relay to channel (value + 1). Value ranges from 0 (ch 1) to 15 (ch 16).

Set relay to respond to a specific note number
CC# Value Comments
99 0 to 7 Selects which port (relay) to configure. Value ranges from 0 (port a) to 7 (port h).
98 2 Value of 2 selects the note number parameter as the one to be configured.
06 0 Value will always be zero when configuring the note number parameter.
38 0 to 127 Sets the note number to which the relay will respond. Refer to a midi note chart.

Set relay duration for note on/off configuration
CC# Value Comments
99 0 to 7 Selects which port (relay) to configure. Value ranges from 0 (port a) to 7 (port h).
98 3 Value of 3 selects the duration parameter as the one to be configured.
06 0 to 127 See below.
38 0 to 127 See below.
Both values will be zero to retain relay state until note off (or on) message is received. Non-zero values must be calculated. Perhaps someone can figure out and post a formula. I always use zero values in my application.

Set relay duty cycle
CC# Value Comments
99 0 to 7 Selects which port (relay) to configure. Value ranges from 0 (port a) to 7 (port h).
98 5 Value of 5 selects the duty cycle parameter as the one to be configured.
06 0 Value will always be zero when configuring the duty cycle parameter.
38 64 Value ranges from 0 (relay disabled) to 64 (100%) duty cycle.

Set relay to be non-inverted or inverted
CC# Value Comments
99 0 to 7 Selects which port (relay) to configure. Value ranges from 0 (port a) to 7 (port h).
98 7 Value of 7 selects the invert parameter as the one to be configured.
06 0 Value will always be zero when configuring the invert parameter.
38 0 or 1 Value can be 0 (non-inverted) or 1 (inverted).

Store configuration to EEPROM
CC# Value Comments
99 100 Value will always be 100.
98 1 Value will always be 1.
06 0 Value will always be 0.
38 1 Value will always be 1.

PS. The formatting was destroyed upon upload to this review board. The CC#, Value, and Comments columns were squashed together into one unreadable mass. Knowing these are three separate columns might make it easier to decipher the information in each section.

Response from Sixty Four Pixels | Jan. 28, 2016

Thanks Mark, and I take the point about the hex values causing confusion.. as a programmer I think in hexadecimal as second nature and forget how confusing it can be, especially for values that look like decimal. I like the way you have presented the messages here and will think about putting the same in the documentation
Cheers
Jason

Neil | Jan. 2, 2016

Very useful piece of kit!

I only originally bought this to let me chain midi stuff but I've found the midi clock function really useful and now use it to sync Ableton with various Volcas and hardware sequencers. Need a midi merge next (or switch box) so I can add the Arpie and Le Strum :-)

Flavio | Dec. 16, 2015

My first DIY!!!

For Relay Switcher : 8 Channel MIDI-to-relay module

Great DIY for beginners - I guess. It took me like 2 hours or so to finish everything and it worked at first shot! Very good and detailed walkthrough for the soldering process, as well as for debugging issues.
I can suggest this kit for soldering starters... ;-)
Flavio.

Luke | Nov. 2, 2015

Worked perfectly. Not too difficult to assemble.

I assembled the kit today and all eight channels are working perfectly. I couldn't be more pleased with my purchase. Seller was easy to get ahold of and was happy to answer my questions.

The kit arrived in great condition, all parts were safely wrapped. Documentation was thorough and relatively easy to follow, even for someone with no previous experience like myself. The configuration app worked fine, but was a little tricky to figure out at first (be sure to read the instructions very carefully)

Thanks for the great product.

Dennis | Oct. 23, 2015

Great kit

For LE STRUM - MIDI Strummed Chord Controller DIY KIT

Was easy to assemble. Clear instructions and parts fit well. Worked first time around. Would highly recommend.

Aad | Oct. 10, 2015

ARPIE is the "Bomb"

I built it in two hours, just relaxed, enjoying assembling, building the unit and placing the parts as described by the manual.
It has a very clear description of the parts, and where to put them on the boards.
No questions here.
When finished, it worked instantly and I love the the way it works.
After fiddling about with the buttons for a few minutes, you get a clear picture of it's cappabilities.
Much of the functions speak for them selfs, and if not, there's always the manual.

Missing anything?
Yes, I would like to see a bypass or THRU function, which keeps the unit in the MIDI chain and allows you to play your live played parts as well.

I ordered a ARPIE case, which came a few day's later because Jason had some trouble with his 3-D Laser cutter.
Communication was very clear and helpfull about this small issue, no problem there...
But the front panel offered not as much protection to the buttons and LED's as I expected.
There's no cut out per LED or switch, leaving these parts as unprotected as is whithout the ARPIE case....

Overall, I give a BIG BRAVO to Jason, offering this small but fine piece of MIDI gear to the world!
Keep up the good work....

Best regards,
Aad

A1 kits from Hotchk155

I've now bought and constructed a number of products from hotchk155. I cant fault the quality of the components, the construction of the pcbs or the documentation. I'd recommend le Strum and Arpie to anyone thats interested. Easily constructed they do just what appears in the tindie videos

For MIDI Switcher: Set your MIDI free!!

I am not the most skilled person on tindle, and so even though the instructions were clear enough, I did take me some time and a little bit of help to get this working, but when it did... wow! You have saved all of my autumn evenings. This is just amazing!
Such a great concept!

Lincoln | April 28, 2015

The Arpie is amazing! Very capable and powerful.

Purchased my unit some time ago and just updated the software to version 4 today. Just incredible! Documentation has improved vastly. The power and functionality of this little device easily holds its own against much higher priced units. The inventor has always been available to answer any questions I had. He is clearly dedicated and works on improvements as feedback and his own ideas dictate. I highly recommend this to any musician wanting to experiment with an arpeggiator.

Jason | April 6, 2015

Fantastic bit of kit and seller really helpful.

I got this a few weeks ago and have been using it constantly since. I also have a Kenton midi thru 5 so it's easy to compare. I like the fact this thing runs off 5v USB power, making it ultra portable with my Korg volcas and Electribe which all run on batteries. These together with a pocket 8000 mah battery = ultra portable midi music. The metranome is another cool feature again for things like the Korg volcas. It also has SIX midi outs... Surly enough for anyone on the go.

Really happy with this and I have already recommended this item on several synth forums.

Chris | March 18, 2015
