By default, all tracks are set to play together. Left click on a track's oscilloscope to toggle the track's mute status, right click the scope to solo the track. We have seen what a track looks like, now let's find out how to create one of our own. Alternately, you can add events one by one by scrolling to an entry point and inserting sounds in step-entry mode. You can use the keyboard in other ways as well.
Controls are available for song or pattern play, and nearly all the editing functions.
If your Linux sound system utilizes the ALSA drivers, and if you have configured SoundTracker for ALSA support, you can use an external MIDI keyboard to enter events. However, you'll need to configure SoundTracker for MIDI input. Clicking the Volume button lets SoundTracker use the MIDI velocity value for the volume of the inserted event. Clicking on the channel button locks MIDI input to a particular track, so that MIDI Channel 1 equals Track 1, MIDI Channel 2 equals Track 2 and so forth. If you select the MIDI channel button, you must change the MIDI Out channel on your keyboard to input data to another track.
