3.1.5. Selecting Strum type

The Strum knob emulates the effect of strumming notes on a guitar. When you move a pick

or your finger across the strings from low to high with a downstroke the strings will sound

with a fixed delay. The lowest, 6th string will sound first, followed by the 5th to 1st string.

When you strum faster the distance between the notes becomes shorter.

When turning the strum knob to the right from the neutral 12 o'clock position, the lowest

notes in the chord will sound first: the chord generator emulates a guitar downstroke.

Turning the knob further right will increase the delay between the notes until at 50 the

maximum delay is reached. Turning even further you'll see how the values change to

quantized values ranging from 1/64 to 1/4.

The Strum knob can emulate both a downstroke strum (by turning the knob right fron the

neutral position) as well as an upstroke strum (by turning the knob left fron the neutral

position). In the neutral twelve o'clock position all notes will sound simultaneously. When

moving the knob to the right, more and more delay is added to the strum until at 3 o'clock

the strum reaches its maximum delay with value 50.

When turning the knob beyond '50', the speed of the strum becomes tempo dependent. To

achieve the slowest possible strum set the tempo rate to 30 (the minimum rate) and the

strum delay to maximum (4).

When turning the knob to the left from its center position a chord will be played as an

upstroke strum. More and more delay is added to the strum until at 9 o'clock the strum

reaches its maximum delay with value -50.

When turning the knob beyond '-50', again the speed of the strum becomes tempo

dependent. To achieve the slowest possible strum set the tempo rate to 30 (the minimum

rate) and the strum delay to maximum (-4).

In the lowest quadrants (with values greater than 50 and -50), the distance between the

notes is quantized to the following values: 1/64, 1/32t, 1/64d, 1/32 , 1/16t , 1/32d, 1/16 , 1/8t , 1/

16d, 1/8 , 1/4t , 1/8d, 1/4. In the above line values with 'd' attached to them are dotted values;

a dotted note is 1.5 times the base note value. If the 1/4th note has a duration of 1 second,

a dotted 1/4th will have a length of 1.5 seconds. Values with 't' attached to them are triplet

values; a triplet quarter note is 2/3rd the length of a quarter note.
