Knowing the tempo and time signature of your sample will allow you to set the loop points quickly
and easily. The SP-808 will estimate the tempo of your sample based on the note type and length
parameters that are set on the Sample Parameter screen and the length of time between starting
and stopping the sampling function. Many sample CD's have the BPM for each sample listed. The
trick is to first determine the length of the sample in order to get the correct BPM. For example, if
you are sampling a two bar drum loop in 4/4 time, you would set the BPM BaseNote to "q" (a
quarter note) and the length to "x 8" (because there are eight quarter notes in two bars of 4/4
time). When you finish sampling, the tempo in the upper right portion of the display should match
the tempo listed for that sample. If it does not match, you can adjust the Length (>End) parameter
until the tempos match. Now, when you play back your sample, it should loop smoothly.
Tip: If you hold down SHIFT and rotate the VALUE/TIME dial, you can change the values in exact
doubles or halves. Also, the Start and Loop points can be moved without changing the length of the
loop by rotating the VALUE/TIME dial while holding the STOP button.
If you do not know the tempo, you can hold down SHIFT and tap the HOLD button in time with the
sample until the tempo is displayed on the screen. This feature is called Tap Tempo and it can be
very helpful. You may need to tap the button several times in order to get the correct tempo.
Note: If you cursor up, you can set the Loop Mode. "START-END" will repeat the entire sample.
"LOOP-END" will allow you to set a loop point that is different from the start point. When you press
a pad, the sample will play from the Start Point to the end point. When the sample repeats, it will
play from the Loop Point to the End Point.
Use the following procedure to set the loop points of your sample:
1. Press TRIM followed by the pad you wish to edit.
2. CURSOR to X (Times) and rotate the VALUE/TIME dial to adjust the length of the loop (total
number of beats). For example, if you have a one measure loop, you will select "4." If you
have a two bar loop, select "8."
3. CURSOR to Length (->End) and rotate the VALUE/TIME dial to adjust the end of the sample
until you get the desired BPM.
4. Play the pad to check your results. Playback will start just before the end of your sample so
you won't have to wait to hear the loop point.
