First, use must produce some samples to sequence.
Open the "Sample Picker" and "Buffer Manager" and
select some .WAV files somewhere.  
Select one of them in the buffer manager.

Then, clicking on the sequencer's background area should
yield a circle.  If you press the "Play" button
you should here that sample play repetitively.

You may select different samples in the buffer manager.

To move a sample, drag it with the mouse.

To delete a sample, right-click on it.

To move a bunch of samples, select them with the middle-button,
then they all drag as a unit.  You can use shift to copy.

By default, the vertical axis represents volume.
By pressing the "By Resample Rate" button, the
vertical axis will represent the frequency (that it pitch).
In this mode you can compose limited melodies.

Each time a new sample is added to the sequence, a
row of buttons pops up to give control over all samples
of that type.  Samples can be selected, hidden, muted, 
deleted, or transposed up/down an octave at a time.

You may enter a filename in the entry box between the
"Save" and "Load" buttons.  Then when you press the save
button the sequence will be saved to that file.

The '/dev/midi' button will open the /dev/midi device (if
needed) and attach to the 'note on' signal.  Then, midi
notes generated will be added to the sequence at the proper 
volume and pitch.  Notes can be added by hardware devices
while the song is playing, and will appear at the appropriate
time.  Clicking on the 'add in time' button will add a note
in the same fashion.  Because there may be a noticable 
latency between input events and sound output, there is
a system lag value which is taken into account when adding
in time or from hardware input.  This value is in seconds.

There are a group of buttons which step a marker through
the sequence and add samples at the marker point.  The 
step size can be adjusted, and the 'auto step' feature can
be toggled to have the marker stepped each time a sample
is added.
