For those who use e-valve equipped instruments.

This week I purchased and installed a wireless MIDI connection from my
computer to my e-valve equipped Duo-Art Piano. I think it will be of
interest to others in the group.

I purchased an off-the-shelf wireless MIDI transmitter and receiver from
M-Audio (http://www.m-audio.com) The model I purchased is called "MidAir"

This product is primarily designed to transmit MIDI signals from a keyboard
or other device on stage to a mixer or computer. As such it was not quite
plug and play for application to send MIDI signals from the computer to the
e-valve system. I basically had to configure the setup reverse to the
design configuration.

Here are the additional items I needed for the installation (with costs in
CDN $):

MidAir transmitter and receiver system $120.00
MIDI Coupler (female/female) $5.00
MIDI Cable (3 foot single lead male/male) $7.50
9 volt 500 mA power supply $17.50 (only one was supplied with the kit and
two are required for our types of setup)

TOTAL $150.00 CDN ($130 USD +/-)

The configuration is as follows:

COMPUTER END
1. Computer with MIDI files
2. USB to MIDI male 5 pin connector (part of the original wired MIDI
interface with the e-valve system) 3. MIDI Coupler (female/female) 4.
MidAir transmitter (powered by 9 volt 500mA transformer, normally battery
power but I opted to use a power supply)

E-VALVE END
1. MidAir receiver (powered by 9 volt 500mA transformer) 2. MIDI Cable (3
foot single lead male/male) 3. E-Valve System input

I have tested this out on my system and so far have not run into any issues,
I installed it and everything worked flawlessly. The transmission range for
this system is about 30 feet, I have tested it to about 25 feet and it seems
to work well. The distance of 25 feet works well for me allowing me to
move the computer out of sight of the piano. I am very pleased.

If anyone has questions I'd be happy to answer them (if I can)
