Desktop Editor Software Manual
Pot Control Method
This is an editor option (it is not stored on the device) which lets you set the method used
for controlling pots (knobs) with the mouse. This can be rotary (where the pot position
follows the position of the mouse) or x–y (where left-right movement gives fine position
control, and up-down movement gives coarse position control). You can set this to the
method you find most intuitive.
Show Note Names
Notes that are displayed can be shown in two ways: either as musical notes ( e.g., C2) or
as
MIDI note numbers ( e.g., 36). You can set this to the setting that is most useful to you.
Setup—settings
There are some options which always apply, regardless of the currently selected
Operating Mode. These global settings are located in the settings section of the setup
tab, and are described below.
Pre-amp Gain (Volume)
The gain of the input pre-amp can be adjusted to optimise the i2Mmusicport for different
signal levels. The gain can be adjusted from −12dB to +15dB in steps of 3dB. Standard
line-level (sometimes shown as −10dBV) corresponds to 0dB. There are two ways to
adjust the gain.
The first way to adjust the gain is to use the i2Mmusicport Desktop Editor Software. This
lets you adjust the gain quickly and also lets you see the correct gain level in dB, which
can sometimes be useful to know. Using the Desktop Editor Software, simply click and
drag the Preamp Gain slider to select your desired gain level.
The second way to adjust the gain is to use the volume control on your operating system
to contol it. However, sometimes this can be awkward to find, or it may not correctly show
the gain values (for example some operating systems will only show an adjustment range
of 0–100).
Send Pitch-Bend Sensitivity RPN
Pitch-bend sensitivity is the setting on a MIDI instrument which controls the semitone
range that can be spanned by the pitch-bend
MIDI control. The i2Mmusicport allows the
pitch-bend range to be set from 1 to 36 semitones. For your
MIDI instrument to sound in
tune with the i2Mmusicport, it is essential that the pitch-bend sensitivity on the
MIDI
instrument matches the pitch-bend range set on the i2Mmusicport.
Although there is no standard value of pitch-bend sensitivity, the most common setting is
2 semitones, this means that pitch-bend messages can bend a note up or down by 2
semitones. This is also the default setting of the i2Mmusicport. However, it is often
desirable to set a larger range such as 12 or 24 semitones (1 or 2 octaves, respectively),
for example to allow long pitch changes when using a guitar tremolo, a theremin, or
trombone.
To make setting pitch-bend sensitivity simpler, many
MIDI instruments support the “Pitch-
bend sensitivity RPN” message (RPN = Registered Parameter Number). By default,
