Program Change
It is often desirable to change modes (presets) without having to touch the
i2M musicport or using the Desktop Editor Software, for example during a live
performance when you want to change settings in different parts of a song.
To make this possible, modes can be selected using the
MIDI program change message.
By default, modes do not respond to these messages. To make a mode selectable via
MIDI
program change simply select a program number on the program change field. When
the i2M musicport receives a corresponding program change message, the appropriate
mode will be activated.
If you are using a sequencer, you can configure it to send the appropriate program
change messages at the correct times so that mode-switching is fully automated.
Alternatively, use a third-party
MIDI foot controller which can be programmed to send MIDI
program change messages and route these messages to the i2M musicport.
Velocity Filter
The i2M musicport is very responsive to how hard you play notes, so you can easily
generate both loud and quiet
MIDI notes. However, some musicians find it difficult to mute
strings sufficiently to prevent unwanted quiet notes being played. These notes, when
they are of very short duration, can sound like audio glitches.
To prevent this, you can enable the velocity filter. When set, only notes whose velocity is
equal to or above the prescribed value will allowed.
Velocity Curve
The velocity of a MIDI note is used to indicate how hard that note was played.
Correspondingly, notes with high velocity are usually played louder than notes of low
velocity.
By default there is a linear relationship between how hard you play a note and the
MIDI
velocity used to describe this. Often, you want more control over how your playing is
translated to sound on your
MIDI instrument and this can be achieved by applying a
velocity curve to transform the original
MIDI velocity into a new MIDI velocity.
Top Tip: When using the i2M musicport to transcribe your music, it can be
useful to set a reasonably large value for the
velocity filter , then
only notes that you play loudly and clearly will be converted to MIDI
which can reduce the number of wrong notes that are transcribed.
