OP-1 uses:

  • .aiff files
  • 44.1 kHz sample rate, 16 bit bitrate

Synth sampler

Bring your own instruments into the OP-1!

Sample single note into it, then play it chromatically, i.e. spread across the keyboard at different pitches.

To sample something

  • Press microphone button
  • Select source in sampling menu:
    • OP-1 mic or plug in cable for mono or stereo input
    • Radio
    • USB
    • Out-in, i.e. sampling what is being played on the OP-1
  • Set the amplitude with the red knob and the sampling threshold with the white knob (i.e. the volume at which it starts recording and below which it ignores the input sound).

E.g. sample a kalimba:

  1. Set recording to OP-1 mic and set volume and threshold to good levels.
  2. Press down C key on keyboard.
  3. Play the C on the kalimba.
  4. Release the C key on the keyboard, or record for the full 6 seconds.

Once the sample is recorded, you can set the start and end points with knobs. Also, you can set the start and end point of a loop to sustain the sample for however long you want.

You can change envelope and effects, or add LFOs, like with other synth settings.

Drum sampler

Works in a slightly different way to synth sampler - it doesn’t matter which key you’re pressing when recording because it doesn’t work chromatically.

Sample can be maximum 20 seconds long.

To sample something

Same as for synth sample. Then the OP-1 slices up the sample automatically into 16 even chunks - mapped to the first 16 keys on the keyboard - and into 8 even chunks that are double the length of the first 16 chunks - mapped to the last 8 keys on the keyboard.

_So it makes sense to record a whole 4-bar-loop and stop it at the right time to get the slice points well distributed and easily get started with slices that are somewhat in time. Rather than starting with e.g. 7 bars and then have to chop up everything manually _

Each key is mapped to a different chunks with defined start and end points that can be adjusted. For each key individually certain parameters can be adjusted, e.g. the pitch with the blue knob. Red knob = play mode.

  • Arrow = sample plays only as long as key is pressed.
  • Arrow with line = sample always plays to the end, even is key is only pressed very shortly.
  • Arrow with G = for samples that should cut each other off, set this mode for all samples that should have this behaviour. Samples that should not play on top of each other.
  • Loop = sample will loop between its start and end point as long as the key is pressed.

Shift + blue knob = playback mode: play sample forward or backward.

Shift + white knob = attack: slope, ramp up, fade in. Helps with clicks and pops if sample is not chopped properly.
