  • Page 16: Introducing The St-224

    This section explains the basic configuration of the ST- 224 as well as some important terms used in this manual. ST-224 Configuration The illustration below shows the basic configuration of the ST-224. As can be seen from the chart, the ST-224 is made up of three main sections. • Sampler Samples the audio signal and performs playback using the pads and sequencer.

  • Page 17: Pads And Banks

    A combination of all settings for pads 1 - 8 is called a "bank". The ST-224 has three banks which are selected with the [BANK 1] - [BANK 3] keys. In effect, the ST-224 therefore gives the user access to a total of 24 pads.

  • Page 18: St-224 Memory Configuration

    When sampling or song recording is performed with the ST- 224, the waveform data and song data are temporarily stored in the main memory. During pad play and song playback, the ST-224 will read data directly from the main memory.

  • Page 19: Bpm

    • 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).

  • Page 20: Manual Sampling

  • Page 21 If you press the [CAPACITY] key, the approximate remaining HINT HINT sampling time in seconds (calculated for HiFi and Mono) will appear on the display. STEP To switch between mono and stereo, use the [MONO/STEREO] key. The indication "Mn" (Mono) or "St" (Stereo) will appear on the display. To change the setting, hold down the [MONO/STEREO] key and use the [-] or [+] key.
  • Page 22 STEP Press the [PAD ASSIGN] key. The number of the most recent sample is shown. STEP Press the [PAD ASSIGN] key once more. Use the [BANK 1] - [BANK 3] keys and the pads 1 - 8 to select the pad to which you want STEP to assign the sample.

  • Page 23: Auto Sampling

    (2) Auto Sampling Besides the manual sampling procedure using the [RECORD] key as described above, the ST-224 also allows auto sampling where the start and stop of sampling is controlled automatically. There are two auto sampling modes: the auto recording mode where sampling starts automatically when the signal level exceeds a certain threshold, and the auto stop mode where sampling stops automatically after a preset interval.
  • Page 24 While holding down the [PLAY/STOP] key, use the [-] and [+] keys to change the auto stop STEP sampling time The value can be set in 1 second steps. The auto sampling time can also be specified in BPM units. To do HINT HINT this, hold down the [BPM] key and use the [-] and [+] keys to...

  • Page 25: Pad Play Mode Operation

    This section explains operation of the unit in pad play mode. In this mode, pads are played to produce their assigned samples. This is the basic operation mode of the ST-224. The playback position and playback mode of each sample are also adjusted in this mode.

  • Page 26: Using The [Source] Pad To Play An External Sound Source

    Using the [SOURCE] Pad to Play an External Sound Source The [SOURCE] pad is a special pad that allows using an externally connected component as sound source for pad play. For example, when a CD player or other source component is connected to the [INPUT L/MONO] jack and [INPUT R] jack, the sound from that source will be heard while the [SOURCE] pad is pressed.

  • Page 27: Assigning A Sample To A Pad

  • Page 28: Assigning A Sample To A Major Scale

    Sometimes it may be useful to assign the same sample to several pads and play the pads with changed pitch (such as when a single bass note was sampled). The ST-224 can automatically assign one sample to pads 1 - 8 and change the pad tuning using a Major scale.

  • Page 29: Setting The Sample Playback Position

    Setting the Sample Playback Position After assigning a sample to a pad, the following three parameters can be changed to specify the playback position. • Start point Normal playback start point. When the pad is pressed, playback starts from this point. •...

  • Page 36: Erasing A Sample

    You can delete a specific sample or all samples from the main memory. This is useful for example to remove all preprogrammed samples or to remove unwanted samples in order to free up memory. Also when all samples are erased, the preprogrammed samples of the ST-224 can be NOTE restored by initializing the unit.

  • Page 37: Optimizing Samples

    Optimizing Samples Samples that are not assigned to pads or any unused portion can be erased to free up memory in the main memory. This is called optimizing. The process can be applied to a specific sample or to all samples. TIME STRETCH VOLUME/BASS EXCITER...

  • Page 38: Matching Bpm Of Pads (Auto Sync)

    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.
  • Page 39 STEP Press the [AUTO SYNC] key. The [AUTO SYNC] LED flashes, and the indication "MAStEr" (master) appears on the display. This guides the user to specify the pad to be used as reference (master). Use the [BANK 1] - [BANK 3] keys and the pads 1 - 8 to select the master pad for auto STEP sync.
  • Page 40 When "rESMPL" is selected as auto sync type, resampling is NOTE carried out with the pitch shift effect applied. This may result in a slight alteration of the sound. When auto sync is completed, the indication "A-SYnC" appears on the display. STEP Hit the master and slave pad together, to check whether the tempo is properly matched.

  • Page 41: Changing Bpm For Every Pad (Auto Sync Advanced Steps)

    Changing BPM for Every Pad (Auto Sync Advanced Steps) As explained in the previous section, the ST-224 regards the length of a sample assigned to a pad as 4 beats, and automatically calculates the BPM value for that pad. However, sometimes it may be desirable to synchronize phrases or patterns with a different beat pattern (such as combining a 4-beat bass pattern with an 8-beat drum pattern or a 2-beat sequencer pattern).

  • Page 42: Using The Internal Effects

    Using the Internal Effects The ST-224 has 22 types of built-in effects. You can select any effect and apply it to the sound of any pad. The [EDIT 1] wheel and [EDIT 2] knob on the unit can be used to adjust effect parameters in real time. It is also possible to synchronize a specific effect parameter with a certain BPM value.
  • Page 43 To turn the effect on permanently, hold down the [LOOP/MARK] pad and press the STEP [EFFECT ON/OFF] key. To turn the effect off again, press the [EFFECT ON/OFF] key once more.
