"Freezing" software instruments
MIDI tracks using a software instrument can be saved to an audio file using the track's Save As option. This
can be very useful if a software instrument uses a lot of CPU power. The software instrument is effectively
replaced by an audio file, but all effects and mixer settings etc. stay the same, so the sound is identical. The
track's File Options Menu can be used to load the MIDI file again (it appears in the File History at the
bottom of the menu). The software instrument will be reloaded automatically. This feature is usually called
bottom of the menu). The software instrument will be reloaded automatically. This feature is usually called
'freeze'.
A software instrument's output level could be too high for an audio file, so the signal gets clipped. If this
happens you can use the MIDI track's Controller editor to turn down the Volume or Expression controllers.
Pro Plus edition users can use 32 bit float type .wav files. These files do not clip the audio signal so the
problem won't occur.
8.1 External MIDI Instruments
An External MIDI Instrument sends the track's MIDI data to a MIDI Out device. This can be either a MIDI (or
USB) connector, a synth on the soundcard, or a software emulation of such a device.
External MIDI Instrument window
Patch section
The large display in the Patch section shows the name of the patch. Clicking the Select button lets you
select a patch by name. The names are stored in a Patch Map file. The small button can be used to select
select a patch by name. The names are stored in a Patch Map file. The small button can be used to select
the Patch Map file that corresponds to your MIDI device (the default file can be selected in the MIDI Out
Device Options window).
The Bank:prog display indicates the bank (optional) and the program used. Bank and program are
numbers (0..16383 and 0..127 respectively) separated by ':' (for example: 1:2 means Bank 1 and Program
numbers (0..16383 and 0..127 respectively) separated by ':' (for example: 1:2 means Bank 1 and Program
2). The bank/program value can be altered by left clicking it. Pressing Enter will accept the new value.
Pressing Esc will cancel the operation. You can use the Page Up/Down and Up/Down Arrow keys to
change the bank and program values.
Channel indicates the MIDI channel being used. If this channel is a special percussion channel (according
to the Patch Map) the Percussion Channel button will light. This button can be used to toggle between the
percussion channel and a non-percussion channel. The button doesn't appear if the Midi Out Device
doesn't have a percussion channel.
Controls section
The Controls section affects the way the patch sounds.
Detune detunes the patch using Pitch Bend messages (the pitch bend range is assumed to be 2
semitones). The value is stored in the MIDI file as RPN 1.
Bright , Reverb and Chorus control MIDI controllers 74, 91 an 93 respectively. Some synths (e.g.
SoundBlaster Live!) may need to be set up properly in order to respond to controllers 91 and 93 (Reverb
and Chorus). Controller 74 (Brightness) may not be supported by your synthesizer.
The MIDI Out Device
A MIDI Out Device can be either a MIDI connector or a synth on the soundcard. MultitrackStudio
Professional supports two MIDI Out devices, the Pro Plus edition supports four. The devices are made
