NOTE: In this mode, the light will flash alternately green and orange, unlike any other
mode, so you can clearly recognise that this mode has been activated.
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 i2M musicport for different
signal levels. The gain can be adjusted from −12 dB to +15 dB in steps of 3 dB. Standard
line-level (sometimes shown as −10 dBV) corresponds to 0 dB. There are two ways to
adjust the gain.
The first way to adjust the gain is to use the i2M musicport 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).
Usually, when you adjust the pre-amp gain using the i2M musicport Desktop Editor
Software, your operating system will detect this change and update it’s volume control to
match. Unfortunately, some operating systems don’t support this feature. In these cases,
when you adjust the pre-amp gain slider, everything works as expected until you
disconnect and reconnect the i2M musicport. During reconnection, the operating
system may reset the volume to its last known value (which now doesn’t match what you
selected!). To prevent this and ensure the pre-amp gain is controlled only by the Desktop
Editor Software, you can enable the exclusive button. When this is enabled, the pre-amp
gain can no longer be controlled using the operating system’s volume control, and it will
not be changed unexpectedly whenever you connect the i2M musicport to your
computer.
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 i2M musicport allows the
pitch-bend range to be set from 1 to 36 semitones. For your
MIDI instrument to sound in
Top Tip: To quickly leave latency test mode, for example if this was enabled by
mistake and you need to stop the test notes that are produced in this
mode, simply press the button on the i2M musicport and this will
immediately return you to normal operation.
