Play sampled sounds

Playing SnapBeat, the simple lo-fi sampler

Playing sampled sounds by hitting pads is the basic and only major function of SnapBeat. When you are on the top menu (LEVEL, EDIT and SETTING are displayed), you can play sampled sounds by hitting each pads and/or receiving MIDI note on messages. In some menu layers, you can’t play sounds by pressing pads. In that case, please press BACK button until it returns to the top of the menu.

Although SnapBeat is polyphony and can play 8 sounds simultaneously, pressing multiple pads simultaneously is invalid and only one sound can be triggered by pressing pad at the time (It’s because SnapBeat detects every pads condition through one shared A/D converter input). If you want to trigger multiple sounds at the same time, please trigger sounds by MIDI IN input.

To hear the sounds, please connect your headphones or speakers with headphone out or line out.

LEVEL

In the LEVEL menu, you can adjust levels of the sampled sounds assigned to each pads.

LEVEL menu of SnapBeat, the simple lo-fi sampler

Rotate a menu dial until right arrow aligns to LEVEL menu. Then press menu dial to enter the menu.

LEVEL menu of SnapBeat, the simple lo-fi sampler

Rotate menu dial and select the sound (pad) which you want to adjust the level. You can monitor sounds of each pads by hitting them. Press menu dial to select the sound.

Selecting EDIT menu, SnapBeat, the simple lo-fi sampler

 Then, the right arrow jumps to the right bars which represents of level (volume) of sampled sound recorded for selected pad. Volume is from 1 to 8.

Adjusting level, SnapBeat, the simple lo-fi sampler

You can decrease or increase the level by rotating menu dial. (In the left photo, the level of sound on pad_2 is five out of eight.) Again, you can monitor sounds of each pads by hitting them anytime.

LEVEL menu of SnapBeat, the simple lo-fi sampler

Press BACK button. The updated level is saved in internal memory and it doesn’t vanish after power off. 

EDIT

Selecting EDIT menu, SnapBeat, the simple lo-fi sampler

Rotate a menu dial until right arrow aligns to EDIT menu. Then press menu dial to enter the menu.

Selecting pad in EDIT menu, SnapBeat, the simple lo-fi sampler

Rotate menu dial and select the pad which you want to edit its sound. Then, press menu dial to enter.

Edit menu_1, SnapBeat, the simple lo-fi sampler
EDIT menu_2, SnapBeat, the simple lo-fi sampler

Rotate a menu dial and select from the options below. Then press menu dial to enter the menu.

  • SAMPLE(LO-FI)
  • SAMPLE(HI-FI)
  • TRUNCATE
  • TRIG(GER)/LOOP

SAMPLE(LO-FI)/(HI-FI)

In SAMPLE (LO-FI) and SAMPLE (HI-FI) menu, you can sample new sound to selected pad. The difference of LO-FI and HI-FI is their recording sound quality.

  • LO-FI
    sampling frequency : about 12kHz
    maximum sample length per channel :  about 12 sec
  • HI-FI
    sampling frequency : about 20kHz
    maximum sample length per channel : about 6 sec

HI-FI sampling is based on below technics to hack the voice recorder chip’s limitation.

  1. Record sound which is played with x0.5 speed.
  2. When playback, the sampled sound is played with x2 speed (SnapBeat does this automatically).

Don’t forget to set playback speed of your audio source to x0.5 when sampling with HI-FI mode.

Hi-Fi mode is suitable for sampling high pitch sounds. Also it’s useful because the sampling segments become finer and it becomes easier to adjust start and end point in TRUNCATE.

Insert Line cable for sampling, SnapBeat, the simple lo-fi sampler

Before starting sampling, please connect your audio source to the line in input of SnapBeat with 3.5mm stereo cable.

Input stereo audio signal is mixed as monaural internally.

TRIG/LOOP

EDIT menu_2, SnapBeat, the simple lo-fi sampler

In TRIG (TRIGGER)/LOOP menu, you can change pad responses and loop setting for selected pad (sound). About pad responses, please refer the next explanation.

pad responses, SnapBeat, the simple lo-fi sampler

You can choose pad responses from 3 different type.

  • DRUM
    When a pad is pressed, sampled sound on the pad is played until its end. This response is suitable for sounds such as drums. 
  • GATE
    When you press the pad, the sampled sound will play. And it will stop when pad is released. In short, the sampled sound will play only during the pad is being pressed. When loop is ON, the sampled sound will be repeated until the pad is released.
  • TRIGGER
    The sound will altarnate between playback and stopped each time the pad is pressed. When loop is ON, the sampled sound will be repeated until the pad is pressed again.

When the right arrow aligns to RESPONSE menu, everytime you press the menu dial, the pad responses changes among DRUM, GATE and TRIGGER.
