QUICK START

Adding Effects to Samples
The SP-303 has 26 effects which can add special characters to the sound. Here�s how to try out these effects and hear what they can do.

4. Turn the CTRL 1�3 knobs to adjust the amount of Filter + Overdrive to be applied. CTRL 1 (CUTOFF): Adjusts the filter cutoff frequency. The more the knob is turned to the left the darker the sound becomes; conversely, turning this to the right (clockwise) gives the sound a brighter, clearer feeling. CTRL 2 (RESONANCE): Adjusts the filter resonance. The more the knob is turned to the right, the more the sound�s particular characteristics are emphasized. CTRL 3 (DRIVE): Adjusts the amount of distortion in the filter. The more the knob is turned to the right, the greater the amount of distortion, creating a wilder sound. 5. To turn the Filter + Overdrive off, press [FILTER+DRIVE]; the light goes out.

Of the twenty-six effects, you can select five of them� Filter + Overdrive, Pitch Shifter, Delay, Vinyl Simulator, and Isolator�by directly pressing their buttons. The other twenty-one effects are grouped together in MFX (the multi-effects). Hold down [MFX] and turn the CTRL 3/MFX knob to select which of these twenty-one effects is to be used. Here, try applying Filter + Overdrive to the sample.
