Eobody2HF / Parameters
Formating messages to host
type
This is one of the most important configuration parameters, since it determines which type of MIDI message the device is
going to send in response to variations in a particular analogue input.
Eobody2 is capable of generating 5 different messages:
• CC: Control number change (Control change) 7 bits
CC: Control number change (Control change) 12 bits (the 5 LSB bits are mapped on CC number + 64
• Note: Note on Trigger
• PC: Program change
• PB: Pitch bend (Variation in pitch) real 12 bits
• PB: Pitch bend (Variation in pitch) mapped 14 bits
• ATm: Monophonic aftertouch (Channel pressure)
CC Control Change
This is the type of message which will likely be most often used for controlling sound parameters. The value of the ana-
logue signal acts directly upon the value of a MIDI controller, using a MIDI controller Value Change message (control
change). The number of the controller can be set by the user. If 12 bits resolution is selected, this message will actually
send two Control Change messages.
The controller specified in the val field will send the 7 least significant bits whilst the controller specified in the “low” field
will send the 3 most significant bits, on the same MIDI channel.
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, lower threshold. Eobody2 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.
low 0 - 127
This field enables the user to configure the note on activation level for trigger messages or for the MSB controller number
with a lower threshold.
hi 0 - 127
This field enables the user to configure the note on activation level for trigger messages or for the MSB controller number
with a higher threshold.
