This field enables the user to set the fixed parameter of a MIDI mes-
sage 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.
This message allows an analogue signal to gene-
rate a channel pressure type MIDI message
(channel aftertouch). This pressure message affects a whole MIDI
channel, regardless of what note is played. The channel number to
which the pressure information is applied is selected by the user.
The noise gate threshold specifies the variation of the analogue signal
that would be detected as a change. If the analogue signal moves
inside the range of the noise gate, no MIDI message will be sent. This
field enables the user to set the width of the range. A large range will
be very effective against strong noise but will make the MIDI value
less sensitive to a relevant change of the analogue signal. For a refe-
rence voltage of +5V a threshold of 8 corresponds to a noise level of
± 40 mV (ie: the analogue has to change at least of 40 mV above or
under its current position to be detected as changing). A threshold of
127 corresponds to a ribbon of ± 620 mV of noise.

This field enables the user to adjust the subsampling filter. SUBSAMP
is a subsampling filter (also called downsampling filter). It will make
eo•body analyse the analogue input not every scan cycle.
Thus, fast changes on the signal will not be detected resulting a low-
pass filter. The number of «wasted cycles» is configured in the Nb
Cycles field.
