Matching BPM of Pads (Auto Sync)

The ST-224 incorporates an auto sync function that matches the tempo (BPM) of a pad to that of a reference pad. This is useful for example to align the tempo of a drum pattern and bass pattern sampled separately.

Using the Auto Sync Function (Basic Steps)

From the duration of a waveform assigned to a pad, the ST- 224 can calculate the tempo, expressed in BPM (quarter note beats per minute). The auto sync function uses this value to match the tempo of the slave pad to that of a reference (master) pad.

Be sure to set the start point and end point so that there is a smooth rhythmic NOTE transition when using loop playback, because the ST-224 uses these points to

make its calculations.

Sync) (Auto Pads of

STEP 1

Sample the drum pattern and bass pattern or any other patterns you want to synchronize,

and assign them to pads.

 

 

 

 

 

 

STEP 2

Adjust the start point and end point of each pad so that the sample for each pad has a

smooth transition when using loop playback.

 

 

 

 

 

The ST-224 considers the length of the waveform assigned to a pad

 

 

as being 4 beats (quarter note x 4), and automatically calculates the

 

 

BPM value for this waveform. Therefore it is necessary to adjust each

 

 

sample so that it loops perfectly before using the Auto Sync function.

 

 

 

STEP 3 Press the [AUTO SYNC] key.

STEP 4 Use the [-] [+] keys to select the auto sync type.

The following two types are available.

• tuninG

The tuning value of the slave pitch is changed, and the sample length is changed. (A new sample is not created.)

• rESMPL

The pitch is kept the same, and a new sample with changed length is created (resampling). This new sample is the assigned to the slave pad. It takes processing time to resample.
