Zoom ST-224 - Manual (Page 19)

BPM (beats per minute) is a tempo unit that indicates the number of quarter notes per minute. For example, a
piece where a quarter note is 0.5 seconds long will have a BPM figure of 120, whereas a piece where a quarter
note is 1 seconds long will have a BPM figure of 60.
The ST-224 handles three types of BPM, which can be set individually.
• Song BPM
Indicates the tempo of a stored song. This value is stored separately for each song.
• Pad BPM
Indicates the playback time of a pad. The ST-224 considers the playback time of a sample assigned to a pad to
be four beats (quarter note x 4) and automatically calculates the BPM for the pad. This serves mainly for
synchronizing the tempo of several pads (Auto Sync feature). When parameters such as the sample start
point and end point, tuning etc. are changed, the pad BPM also is adjusted automatically.
• Effect BPM
Serves for synchronizing the parameters of certain effects (delay time, flanger modulation speed, etc.) to a given
tempo. The synchronized parameter depends on the effect type (some effect types do not have a parameter that
can be synchronized).
The value of Effect BPM is same as Song BPM unless edited.
For each type of BPM, the setting range is 40 - 250. NOTE
