The Synth Rack
Beats Per Minute: The midi file contains data that defines the BPM for the song. This data may change throughout the song. You can also change the overall playback speed by changing the Speed factor. Use the four up/down buttons to change the factor in units of tenths (”.1”) or hundreds (”.01”). You can activate a metronome that wil click at the current BPM speed.
Playback volume: There are two sliders you can pull, Left and Right. Normally these are synced to each other and change at the same time. To change them separately you need to un-toggle the Sync button. Above the Sync button there is a Soft button. Toggle this to switch on/off the soft limiter which reduces distortion when the signal becomes out of range.
Output VST Effects (”Fx”): You can assign third party VST effects to 17 separate lines, or ”busses”. The first bus is the Main bus, which is always used by all midi channels. The other 16 busses can be assigned to each midi channel separately. Below the ”Bus chain” drop-down list there are six buttons for manipulation of VST effects. You have to install or register VST effects at first in ”Setup and Options” before you can use them.
Playback Range: Here you can define what part of the tune you want to play. You can select to use Markers, which are either defined in the midi file or later by you (and stored in the arrangement file), or you can select to play an area defined by a set of Bar and Beat numbers. The Playback range is also visible in the playback percentage box to the left, where the markers are show as two vertical lines in the progress bar, and the Bar/Beat start and stop values are shown as two small triangles below the progress bar. If you have selected a Playback range, you may select to loop it a number of times or indefinitely.
Playback progress: The two small triangles below the progress bar can be pulled around to define the Bar/Beat playback range. There are nine small buttons: Back to start, Back one or ten bars, Play/Stop, Pause, Forward to next marker, Forward one or ten bars, Create a new marker (markers can be seen and manipulated in the Pianoroll pane), Go to next song of the playlist, and Set the songs final decay length (the time SynthFont will wait for the last notes do ring off). There is one big button: Player. This toggles the real time Player Piano window.
Synth Options: This buttons opens the Setup and Options dialog and goes directly to the Synth options in the dialog.
Leardini system: This button opens the Leardini system dialog. Click the region to read more about this special feature for blind users.
Voices: this is also for information only, it shows the number of simultaneous voices, or wave samples, playing at the same time (often referred to as “polyphony”). SynthFont can handle up to 1024 voices, but your CPU may put limitations on the number you can reach without cause disruptions in the audio output. NOTE that when playing to a file, there is no CPU limitation.
CPU: this is for information only, it shows the CPU load while playing.
