+The FM synthesizers Furnace supports are four-operator, meaning it takes four oscillators to produce a single sound.
 
+These apply to the instrument as a whole:
+- **Feedback (FB)**: Determines how many times operator 1 returns its output to itself. (0-7 range)
+- **Algorithm (AL)**: Determines how operators are connected to each other. (0-7 range)
+  - Left-click pops up a small "operators changes with volume?" dialog where each operator can be toggled to scale with volume level.

+    - Middle-click pauses and unpauses the preview.
+    - Right-click returns to algorithm view.
+
+- **LFO Frequency Sensitivity**: Determines the amount of LFO frequency changes. (0-7 range)
+- **LFO Amplitude Sensitivity (AM)**: Determines the amount of LFO amplitude changes. (0-3 range)
+
+These apply to each operator:
+- The crossed-arrows button can be dragged to rearrange operators.
+- The **OP1**, **OP2**, **OP3**, and **OP4** buttons enable or disable those operators.
+- **Amplitude Modulation (AM)**: Makes the operator affected by LFO.
+- **Hardware Envelope Generator (SSG-EG)**: Executes the built-in envelope, inherited from AY-3-8910 PSG. Speed of execution is controlled via Decay Rate. YM2610/YM2612 sound source only.
 - **Attack Rate (AR)**: determines the rising time for the sound. The bigger the value, the faster the attack. (0-31 range)
 - **Decay Rate (DR)**: Determines the diminishing time for the sound. The higher the value, the shorter the decay. It's the initial amplitude decay rate. (0-31 range)
-- **Secondary Decay Rate (DR2)/Sustain Rate (SR)**: Determines the diminishing time for the sound. The higher the value, the shorter the decay. This is the long "tail" of the sound that continues as long as the key is depressed. (0-31 range)
+- **Sustain Level (SL)**: Determines the point at which the sound ceases to decay and changes to a sound having a constant level. The sustain level is expressed as a fraction of the maximum level. (0-15 range)
+- **Secondary Decay Rate (DR2) / Sustain Rate (SR)**: Determines the diminishing time for the sound. The higher the value, the shorter the decay. This is the long "tail" of the sound that continues as long as the key is depressed. (0-31 range)
 - **Release Rate (RR)**: Determines the rate at which the sound disappears after KEY-OFF. The higher the value, the shorter the release. (0-15 range)
-- **Sustain Level(SL)**: Determines the point at which the sound ceases to decay and changes to a sound having a constant level. The sustain level is expressed as a fraction of the maximum level. (0-15 range)
 - **Total Level (TL)**: Represents the envelope’s highest amplitude, with 0 being the largest and 127 (decimal) the smallest. A change of one unit is about 0.75 dB.

+
+- **AM Depth**: amplitude modulation depth. YM2151 sound source only.
+- **PM Depth**: pitch modulation depth. YM2151 sound source only.
+- **LFO Speed**: LFO frequency.
+- **LFO Shape**: LFO shape. Choose between saw, square, triangle, and random.
+- **OpMask**: toggles each operator.

+## OP1-OP4 Macros
+
+All parameters are listed above.
 
 ## Macros
 
-Macros define the sequence of values passed to the given parameter. Via macro, aside previously mentioned parameters, the following can be controlled:
-
-- **LFO Frequency**
-- **LFO Waveform**: _WARNING:_ this parameter affects only YM2151 sound source!
-- **Amplitude Modulation Depth**: _WARNING:_ this parameter affects only YM2151 sound source!
-- **Frequency Modulation Depth**: _WARNING:_ this parameter affects only YM2151 sound source!
-- **Arpeggio Macro**: Pitch change sequence in semitones. Two modes are available:  
-  - **Absolute** (default): Executes the pitch with absolute change based on the pitch of the actual note.
-  - **Fixed**: Executes at the pitch specified in the sequence regardless of the note pitch.
+- **Arpeggio**: Pitch change sequence in semitones.
 - **Noise Frequency**: specifies the noise frequency in noise mode of YM2151's Channel 8 Operator 4 special mode.
+- **Panning**: toggles output on left and right channels.
+- **Pitch**: fine pitch.
+  - **Relative**: pitch changes are relative to the current pitch, not the note's base pitch.
+- **Phase Reset**: Restarts all operators and resets the waveform to its start. Effectively the same as a `0Cxx` retrigger.
 
-Looping: You can loop the execution of part of a sequence. Left-click anywhere on the Loop line at the bottom of the editor to create a loop. You can move the start and end points of the loop by dragging both ends of the loop. Rigkt-click to remove the loop.
