A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
To everyone who loves electronic musical instruments.
We present to you...
midiglue (midi + glue)
A compact MIDI converter & MIDI effects unit.
midiglue is a control box that can interconvert between MIDI, USB-MIDI, CV/GATE. It also acts as a MIDI effects unit, a sequencer, and an instrumental performance supporter. Plus, it also comes with a preset editor which can extend the pre-existing presets into your own desired MIDI effects.
Function #1 : Interconversion between different types of input/output
midiglue supports USB MIDI host device, legacy MIDI, CV/GATE/SYNC, Footswitch. midiglue can convert signals between any combination of the above. In addition, you can also split, merge, route, and assign multiple parameter to a CC (Control Change).
You can create your own MIDI effects, or create some complicated routings. You can create these using a software editor that we have developed. The software editor is like a form of modular patching.
midiglue will provide you with perfect functions, just for your live performances.
We'll show you some examples of a connection settings using midiglue .
If you wanted to create a setting like this, you would have had to purchase a converter that only offers a single function (Converting. Of course!) for an unreasonable price, or a laptop and an audio interface that would've taken up more space than a single gadget.
With midiglue, you can adapt to any kind of situation with just a single device!
Example of converting USB MIDI to a legacy MIDI (CV/GATE)
Example of routing using midiglue
Example of another routing usage. You can convert the foot-switch and breath controller inputs to a arbitrary MIDI message and use the signal to operate other devices.
Example of using midiglue as a MIDI effects unit.
Example of programming midiglue as a sequencer.
Is midiglue complete?
midiglue is still in development!
2 month ago, we came up with an idea of midiglue during the development of sigboost. We planned a schedule to make midiglue a working product, and we have developed the software editor and the prototype of the hardware. There are still many bugs in the prototype, but it's functioning very well and we are having a very fun time playing with the midiglue. With a little more time and your backup through kickstarter, we can improve the performance of midiglue and expand the possibility of the hardware, making it viable for live concerts / DJs.
midiglue's functions, such as will not change from the descriptions above. The form of the casing on the other hand will likely be changed several times. (The picture of the midiglue above is not the final form.) Please refer to the "about the casing" for more information.
Our focus is to create
Compact / Easy to carry product
Robust and usable product for real live performances / DJs
Thank you for you understanding.
We will actively report our progress to our backers, and promise to answer to all of your feedback. Let's create midiglue together!
This is a sample of using an unique arpeggiator delay. (This is performed by 1 person.)
The setup is a midiglue and Nord Stage connected with a send/return.
The sound of the piano is the real note that is being played, and the round FM synth is the effect of the midiglue.
The last performance in the top video is using this effect also.
Multi-purpose Analog OUTPUT : 3.5mm, TRS x 2 (CV, Gate, Sync)
USB-Device : Micro-B port
USB-Host : Full size USB port (Supports USB-MIDI compliant devices) ※ Power supply from a device port is necessary when using as a USB-HOST. ※ Host使用時はデバイスポートからの給電が必要です。
About the casing
In the prototype, we are using a top panel created with a PCB and a 3D printed case which is screwed together.
We are reviewing about how the release version should look like, and the most leading idea is to create all sides of the casing with PCB. PCB is close to a FRP (Fiber-Reinforced Plastic) which is very strong and used in an exterior panel for a ship. The circuit will be completely isolated and will fit inside the casing as well.
※ The product in the image has no relation between midiglue.
The reason we are planning to design it like this is mainly the cost. Sheet metal processing or simple metallic mold really looks nice, but it costs much more and affects the price of the hardware. We want midiglue to have an easy to reach price and with full of functions. That is why we are planning to create the case as above.
For the reward with midiglue development board, we are going to send you a bare board. For those who want to acquire midiglue with low cost, or those want to create your own case, or maybe those who wish to only program the effects and not using it out of you home.
The development board will look similar to the image below. (Not a final version)
リワードにあるmidiglue development boardでは、筐体のない基板むき出しのものをお送り致します。低コストで機能のみをお求めいただきたい方や、筐体を自作したい方、持ち出さずにプログラミングのみを楽しみたい、といった方のために用意しました。
We are a team of Tokyo University students and Tsukuba University OBs and also a member of the "sigboost" project, which was to create a FPGA programmable digital instrument. midiglue is a project that got the idea from the needs and the user feedback while developing sigboost. It is also a project to solve the problem that the sigboost had, and also a project to survey the scope of the customers. For more information about sigboost, please refer to this site here.

The most hardest part of the midiglue project is the mass production of the hardware itself. Hardware manager Shota Moriguchi has been creating many gadgets through out his years, and has a good experience with how to efficiently design an efficient and compact gadgets using circuit boards. On the other hand, he does not have an experience with using metallic mold or mass production of hardwares.
But fortunately we have a connection between other experts with those who create gadgets or those who are at the large instrument producers, who can give us feedbacks and help develop our products.
Other risks are the MIDI-USB host functions. Some MIDI controller is designed with a USB hub inside. To deal with these devices, we must modify the host-driver that the chip vendors provides us. But modifying the host-driver is very difficult and most of the commercially available MIDI converter is not compatible with these MIDI devices. We will try to solve this problem but we might prioritize the delivery of the product when considering with man-hours. If this is the case, we are considering to support with the firmware update after the devlivery.
midiglue is a hardware project, so please be aware of the delay of manufacturing and delivery which may be caused by supply delays and natural disasters and such cause.
