Miduino (or Arduino) USB to MIDI Drivers Installation Guide


There are 3 steps:

1) Install the Virtual Com Port (VCP), USB to Serial driver is available from  the Arduino Development Environment. 

2)  You can use a MIDI to Serial bridge like Hairless MIDI. to connect Windows MIDI data from one bit of software to another, you will also need a Virtual MIDI pass-through driver, like loopMIDI, or alternatively the older MIDI Yoke (MIDI Yoke is not recomended for Vista or newer.) Or you could install the older Windows XP/2K Roland  Serial to MIDI driver.

3) Once you have finished installing the drivers the Miduino is ready to be used over USB.



1) If MIDI communication is required NOT using the USB drivers, then normally MIDI works at 31250 Baud rate, so the Baud rate needs to be switched.

2) Running more than one programme using the USB/MIDI Port can cause a conflict.  Also sometimes switching between programmes can sometimes cause an error on the USB/MIDI Port, which generally can be cured by removing and replacing the USB cable from the computer.

Installing the FTDI drivers

Download  and save the FTDI  or the Arduino USB drivers. 

Now, when you plug the Miduino (or Arduino) Board into the USB socket you should get this screen:

Choose the second option as shown above.

Press 'Next' and you will see the following dialogue window:

Select the first option and browse to a folder where  you downloaded the FTDI drivers, Press 'Next'

After some time the Hardware Wizard will start installing drivers:

When it finished you will see this dialogue:

The driver should use COM1 or COM2. Open Device Manager and expand 'Ports(COM&LPT)' group. In this case it was using COM19:

In this case right click on the port and select 'Properties':

In the Properties window select 'Port Settings' tab and click 'Advanced':

And in the next window change port number to either COM1 or COM2:

and click 'Ok' and then 'Ok' again.

In the Device Manager, click 'Action->Scan for hardware changes' and after that you'll see the port with the assigned port  number:

The FTDI driver installation is now complete, but we are only half way through.



Installing Roland Serial to MIDI driver

Download the Roland Serial to MIDI driver. Unpack it anywhere on your hard-drive and you should have files in the RDSMIDNT folder, including RDSMIDNT.INF: 

Open 'Control Panel' and click 'Add Hardware':

In the 'Add Hardware Wizard' click 'Next':

In the next screen select the first option:

Scroll down the list, choose 'Add a new hardware device' and click 'Next':

Select the second option and click 'Next' again:

In the presented list select 'Sound, video and game controllers':

On the next screen click 'Have Disk...':

And the browse to the folder where you unpacked the driver:

Click 'Ok':

Click 'Next':

And 'Next' again:

It will start installing drivers:

This dialogue will pop up. Uncheck everything (e.g. Remove tick from 'Use Multiple Ports' box) and select the COM port which you set when installing the FTDI USB drivers:

Click 'Ok'

And click 'Finish':

Then it will ask to reboot:

After the reboot you can see the 'Roland Serial MIDI Driver' in the Device Manager:

Miduino (or Arduino) is now ready to be used in  any MIDI capable software. This is an example in MIDI-OX:
