How do I use the FM synth?
OP-1tutorialguide
The FM synth on the OP-1 is a frequency modulation engine inspired by classic FM synthesizers like the DX7. It's selected under the synth engines menu and uses operators to create complex harmonic tones.
Selecting FM
- 1.Press Synth key
- 2.Press SHIFT + T1 to browse synth engines
- 3.Turn the blue encoder until you see "FM" on screen
- 4.Press T1 to confirm selection
Basic Parameters
The four encoders control FM-specific parameters. These typically include:
- Blue encoder: ratio or frequency relationships between operators
- Green encoder: modulation amount or operator configuration
- White encoder: feedback or algorithm selection
- Orange encoder: output level or additional modulation depth
Envelope (T2)
Shape your FM sound's volume over time:
- Blue = attack
- Green = decay
- White = sustain
- Orange = release
Effects and LFO
Add movement and character using T3 for effects and T4 for LFO modulation. These work the same across all synth engines.
Saving Presets
Hold any sound key (1-8) for 5 seconds to save your FM patch to that slot.
