Eowave Eobody3 - Manual (Page 6)

• Note on message
N-ON trigger hi-low
The analogue signal must correspond to an envelope changing with time and which has a
maximum value. 3 parameters need to be specified: note sent, higher threshold, and lower thresh-
old. Eobody3 analyses this envelope: once the envelope has reached the higher threshold, a MIDI
note on message (NOTE ON) is generated. The velocity associated with the note is fixed to 127.
The note number contained within the message is adjustable by the user. As long as the envelope
stays above a threshold point, named NOTE OFF threshold, the note is maintained (no new MIDI
message is sent). When the level falls beneath the NOTE OFF threshold point, a MIDI NOTE OFF
message is sent to turn the note off. To sustain the note for a long period of time, the NOTE
OFF threshold point must be set on a small value. Conversely, to make the note stop shortly after
the peak has been detected, the NOTE OFF value must be higher. This type of message is useful in
using sensors to generate MIDI notes.

Program Change message PC
The analogue signal must correspond to an envelope changing with time and which has a maxi-
mum value. You will have to specify 3 parameters, Program Change sent, higher threshold, and
lower threshold. Eobody3 analyses this envelope: once the envelope has reached the higher
threshold, a MIDI Program Change message is generated. The Program Change contained within
the message is adjustable by the user. As long as the envelope stays above a threshold, named
lower threshold, the Program Change is maintained (no new MIDI message is sent). When the level
falls beneath the lower threshold, the Eobody3 is ready to receive a new Program Change
message.
• Pitch Bend PB
This message allows an analogue signal to generate a MIDI message of the pitch change type
(pitch bend). Pitch is usually coded over 14 bits. If the 7 bits resolution is chosen, they will be
mapped on the 7 most significant bits of pitch information controlled by the analogue signal.
However, since Eobody3 does 12 bits conversions internally, the whole 12 bits can be mapped to
take better advantage of the pitch bend message. This message is used to simulate the pitch
changing wheels available on most MIDI keyboards.
• Monophonic Aftertouch ATm
This message allows an analogue signal to generate a channel pressure type MIDI message (chan-
nel aftertouch). This pressure message affects a whole MIDI channel, regardless of what note is
played. The user selects the channel number.
• message
Channel: [1-8]
This field enables the user to select a MIDI channel to which the MIDI message will apply (1 to 8).
• value val: 0 - 127
This field enables the user to set the fixed parameter of a MIDI message associated with an
analogue input. This parameter value may correspond to a MIDI note number, a MIDI controller
number or a MIDI program number, depending on the type of MIDI message, which is chosen.
