midiBeam V2 Wireless MIDI Interface

A pair of devices connecting wirelessly: TX02 transmitter (powered by 2 AAA batteries) and RX02 receiver (powered by USB). MIDI output over DIN and USB.

The midiBeam V2 wireless MIDI interface connects your MIDI instrument (or any MIDI source) to your synthesizer or computer through radio, at the 2.4GHz frequency range, without any cable connection. There are at least two typical applications where it has obvious advantages:
1. If you have a battery powered mobile MIDI instrument you will be free to move around the stage without any cable if you use midiBeam. You can use a mobile keyboard hanging in your neck from Roland, Casio, etc., or a wind controller, like the AKAI EWI 4000s or the Yamaha WX5.
2. If you are fed up with the many cables hanging around in your studio, you can reduce the number of cables if you use midiBeam. Unlike other wireless MIDI solutions midiBeam is a very cost efficient replacement for a MIDI cable, while the delay latency is perfectly negligible, with 0.3 msec, about 10% of other wireless solutions.
When you turn on both TX02 and RX02 if the two devices are not paired (“Pairing” means tuning them to a common radio channel), then both of them will blink slowly, with a short blink. The units are paired to a unique common radio channel by a simple press of the button on either unit. This means that they allocated one of 76 radio channels for themselves in the 2.4 GHz range where midiBeam operates.
You can start to play your keyboard, and whatever you send into the MIDI IN of TX02 (the DIN plug hanging on a short cable), will appear on the DIN and USB outputs of RX02. Both devices will store their channel settings in permanent memory, so when you turn them on next time they will remember on each other. During the pairing process midiBeam will automatically avoid radio channels with activity from other devices, also from other pairs of midiBeam.

The most important advantages of midiBeam V2 Wireless are:
1. Very reliable wireless MIDI connection.
2. Long distance range, LOS up to 350 meters.
3. Extremely low latency, 0.38 milliseconds.
4. Automatic pairing of TX and RX devices.
5. Intelligent channel search avoiding busy channels in the 2.4 GHz range.
6. Low power consumption of the TX device, 65 hours with two AAA batteries.
7. Free software upgrades available.
8. RX can be used as a class compliant MIDI interface.

1. Proprietary radio protocol for extremely low latency, 0.38 milliseconds.
2. Automatic pairing of TX and RX devices.
3. Intelligent channel search avoiding busy channels in the 2.4 GHz range.
4. Transmitter is turned on only for the minimal time of radio transmission, thus low power consumption of TX device, 65 hours with two AAA batteries.
5. RX can be used as a class compliant MIDI interface.

1. An Italian opera production, where a keyboard was played on a boat in a lake, and the transmitted MIDI signal was driving synthesizers on shore.
2. In the London theatre production “Ocean At The End Of The Lane” there is a 4 meter high, huge scary spider-like puppet with 5 legs. With membrane switch keypad contacts under each foot the sensors were connected to a midiBeam 4Control interface box, and the MIDI signals were transmitted by midiBeam V2 Wireless to the off-stage technicians. Every step of the giant generated a unique bomb-like sound.

It connects to every possible MIDI device, replacing a MIDI cable with wireless connection. Additionally, the RX02 functions as a class-compliant MIDI interface.

Potential customers are highly motivated by seeing prominent users like Herbie Hancock and the late Chick Corea.

The next product will be midiBeam Wireless USB, serving as a USB host for small portable instruments that do not have DIN MIDI, and must be supplied through USB.
