The modes f, g and h are more simple. In this case the corresponding Midi messages
control change, after touch or program change are generated. If control change is
selected the controller number is adjusted by the parameter 3-3 Ctrl number. The
Midi messages are sent on the Midi channel adjusted in menu 3-1.
In case of pitch bend (modes c, d, e) data are sent with the maximum resolution (2
Midi data bytes). The Midi receiver has to support pitch bend high resolution if you
want to take advantage of this feature. Otherwise audible pitch steps will occur.
2-2 Midi event [2]
Range a - f
This parameter refers to the Midi message assigned to the pressure sensor [2]. It has
also an influence to the function of the CV2 output.

b Pitch+
c Pitch-
d Control change
e After touch

The construction of the pressure sensor is much simpler compared to the high
resolution position sensor. It is made with conductive rubber and works not as
accurate as the position sensor. The resistance of the conductive rubber changes
with varying pressure but the coherence between pressure and resistance is not very
accurate. Even some difference of the pressure sensor behaviour over the length of
the manual may be possible as the conductive rubber has tolerances over this length.
Even a considerable pressure has to be applied to activate the pressure sensor. So
the pressure sensor cannot be used for sensitive control applications.
As the pressure sensor generates no data before the position sensor is touched the
pressure sensor can be used to modify the data generated by the position sensor
(e.g. volume, modulation depth or speed, pitch, filter frequency).
a Off
In this case no Midi messages and no CV2 is generated.
b Pitch+
In this mode only positive pitch bend data are generated. The pitch of an incoming or
with the position sensor generated Midi note increases as the pressure is intensified.
c Pitch-
In this mode only negative pitch bend data are generated. The pitch of an incoming
or with the position sensor generated Midi note decreases as the pressure is
intensified.
d/e/f
These modes are equivalent to the modes f/g/h of the position sensor in chapter 2-1.
Pay attention that CV2 and the data of the Midi message generated by the pressure
sensor will return to zero (d,e,f) resp. neutral value (b,c) as soon as the manual is
released. This may cause unexpected consequences. If e.g. volume (Midi control
change #7) is assigned the loudness is set to zero in the Midi equipment connected
to R2M. If the mode for the pressure sensor is changed after volume zero has been
sent the Midi equipment seems not to respond as the loudness is still zero. In this
