mi.1

Can the mi.1 be used with equipment that only features a MIDI IN connector??

No, the mi.1 will not function correctly due to a lack of power.

Can the mi.1 be used with equipment that only features a MIDI OUT connector?

When connected to the MIDI OUT connector, if the mi.1's LED flashes, the device will work.

Can the mi.1 be used with equipment featuring MIDI connectors that operate at 3.3V?

Yes, the mi.1 can operate at 3.3V

Can mi.1 devices be connected to each other, for example to facilitate wireless MIDI between two instruments?

No, connecting mi.1 devices to each other directly is currently not supported.
However, it is possible to achieve wireless MIDI between two instruments by using mi.1 devices connected to the same iPhone/iPad, then bypassing the MIDI signal using a MIDI Bridge app.

However, such a connection may not be suitable for real-time performance due to the increased latency.

What is the maximum connection range (distance) supported by the mi.1?

The maximum distance is difficult to specify categorically, as connection stability/reliability is heavily influenced by radio wave conditions and obstacles.
However, it is recommended that equipment connected to the mi.1 be placed within a range of 10 meters. In areas with good radio wave conditions, it may be possible to use the mi.1 at greater distances, however communication data errors will likely increase, and latency will become more noticeable.

When using multiple mi.1 devices, it is possible to change the name of individual devices for easier recognition?

Yes, the mi.1 device name can be changed via the following SysEx message:

F0 00 02 08 10 55 00 01 nn nn nn nn nn nn nn nn 20 20 20 20 20 20 20 20 F7
nn=Ascii Character
The length of the name is limited to 8 characters.

For example, in the case of "ABCDE", the SysEx message would be:
F0 00 02 08 10 55 00 01 40 41 43 44 45 20 20 2020 20 20 20 20 20 20 20 F7

How can I check the firmware version of the mi.1?

The mi.1 firmware can be checked in the Piano Jukebox app, and will be shown when selecting the Firmware Update function.
However, in the case of earlier mi.1 versions that may not support this app, the firmware version can be checked by using a commercially available Bluetooth LE tool.
The following video demonstrates how to check the mi.1 firmware version using the free Bluefruit app:

Is the mi.1 guaranteed to function with any device featuring MIDI connectors?

The mi.1 is developed to function correctly with equipment that conforms to the MIDI Specification 1.0 circuit standard. However, equipment that utilises its own MIDI circuit design may not function correctly with the mi.1.
A list of known compatible/incompatible devices is available from the following URL:https://docs.google.com/spreadsheets/d/1mYRWBT_WT1BX2bG30O6WJ7EzYZyRlLVrkLB3zK27Dl0/edit?usp=sharing

Is it possible to use the mi.1 with (incompatible) equipment that does not produce a power supply from the MIDI connectors?

If the equipment does not produce a power supply from the MIDI connectors, it may still be possible to use the mi.1 by utilising a commercially available MIDI routing box. However in this case an additional power supply will be required.

Alternatively, customers who are familiar with electrical work may wish to create an external circuit to power the mi.1. Please contact support@quicco.co.jp to receive a circuit diagram and instructions for this modification.

What are differences between Rev.2 and Rev.3?

Rev.3 increases the maximum Bluetooth throughput (transfer rate) by approximately 3 times compared to Rev.2. This allows large amounts of MIDI control and SysEx data to be sent and received with greater stability. In addition, latency when playing chords has also been improved.

mi.1 connect app

I purchased an early mi.1 via the IndieGoGo campaign - how can I update the firmware to the latest version?

If the early mi.1 device is running the V1.0.x firmware, it can be updated to V2 using the mi.1 connect app. After updating to the V2 firmware, please use the Piano Jukebox app to update to the latest version.

The following video demonstrates how to update to the V2 firmware using the mi.1 connect app:

iPhone/iPad

Will the mi.1 function automatically after launching the MIDI app?

Many MIDI apps will connect to the mi.1 automatically after launching. However depending on the app, it may be necessary to manually select the mi.1 in the apps' MIDI settings.

Does Bluetooth MIDI have a big latency/delay compared to wired MIDI?

For some individuals, Bluetooth MIDI does not add significant latency, however others may find the delay to be more noticeable.

According to internal benchmarks, the difference between a wired MIDI connection and the mi.1's Bluetooth MIDI connection is 8.4 ms.
(Average value of test performed 100 times using Yamaha UX-16 MIDI interface connected via Lightning to USB Camera Adaptor.)

How many mi.1 devices can be paired to a single iPad simultaneously?

Quiccosound has successfully paired 4 mi.1 devices to a single iPad simultaneously. When attempting to pair 5 (or more) mi.1 devices, simultaneously connection is lost.
(This information will be updated upon receiving confirmation from Apple.)

Is it necessary to pair the mi.1 with the iPhone/iPad every time?

According to the current iOS and mi.1 specification, if the Bluetooth connection is broken, it is necessary to manually pair the devices from the Bluetooth MIDI device screen.

MAC

How can I check if my Mac supports Bluetooth 4.0?

To check if a Mac's hardware supports the Bluetooth 4.0 standard:
Open the Audio MIDI Setup, then double click the Bluetooth icon in the MIDI Studio. If the device list appears, Bluetooth 4.0 is supported.If the device list does not appear and the mi.1 is incompatible, a "MIDI over Bluetooth is not supported" pop-up will appear.

Is it possible to use the mi.1 with an older Mac that does not support Bluetooth 4.0?

For older Macs, Bluetooth 4.0 support can be added by attaching a commercially available USB Bluetooth adaptor. In addition, Mac OS 10.10 (Yosemite) is also required for MIDI over Bluetooth LE functionality.

Other

Is it possible to use the mi.1 on Windows PCs?

No, the Windows OS does not support Bluetooth MIDI and therefore cannot communicate with the mi.1.

Is it possible to use the Korg BLE-MIDI driver to use the mi.1 on Windows PCs?

Under the current Windows specification, it is not possible to pair with the mi.1.

Is it possible to use the mi.1 with Android devices?

While MIDI over Bluetooth LE support has been implemented in Android 6.0 (Marshmallow), Quiccosound has not checked the mi.1. Android is therefore currently unsupported.
