XFMN-01 - Cross-FM Noise Synthesizer

Cross-FM synthesizer combining noise and modulation.

Overview

Two-operator FM synth with delay and filter. Use algorithm, octave, and filter modes to shape the sound.

Parameters

DELAY TIME (0.0–1.0, default 0.05) - Delay time (displayed as 0.001–5.0s) - Examples: - Value = 0.0: 0.001s - Value = 1.0: 5.0s

DELAY FEEDBACK (0.0–0.95, default 0.3) - Delay feedback - Examples: - Value = 0.0: No repeats - Value = 0.9: Long repeats

DELAY MIX (0.0–1.0, default 0.35) - Delay mix - Examples: - Value = 0.0: Dry only - Value = 1.0: Delay only

INDEX 1 (0.1–5.0, default 4.0) - FM index depth for operator 1 — controls the modulation amount applied to operator 1 - Higher values produce more complex, brighter timbres - Examples: - Value = 0.1: Subtle modulation, near-sine tone - Value = 5.0: Heavy modulation, dense harmonics INDEX 2 (0.1–5.0, default 2.0) - FM index depth for operator 2 — controls the modulation amount applied to operator 2 - Examples: - Value = 0.1: Subtle modulation - Value = 5.0: Heavy modulation OUTPUT GAIN (-24 to +24dB, default 0dB) - Output gain - Examples: - Value = -24dB: Low level - Value = +24dB: High level

RATIO 1 (0.1–15.0, default 1.0) - Operator 1 frequency ratio vs base pitch (0.1x – 15x) - Integer ratios (1, 2, 3...) produce harmonic tones; non-integer ratios create inharmonic, bell-like textures - Examples: - Value = 1.0: Fundamental pitch - Value = 2.0: Octave above - Value = 0.5: Octave below - Value = 1.41: Inharmonic, metallic tone RATIO 2 (0.1–15.0, default 1.0) - Operator 2 frequency ratio vs base pitch (0.1x – 15x) - Examples: - Value = 1.0: Fundamental pitch - Value = 3.0: Third harmonic - Value = 7.5: Complex inharmonic ratio FILTER Q (0.2–6.0, default 0.8) - Filter resonance - Examples: - Value = 0.2: Wide peak - Value = 6.0: Sharp peak

PITCH 1 (1–1000Hz, default 440Hz) - OP1 frequency - Examples: - Value = 1Hz: Low - Value = 1000Hz: High

PITCH 2 (1–1000Hz, default 440Hz) - OP2 frequency - Examples: - Value = 1Hz: Low - Value = 1000Hz: High

FILTER CUTOFF (20–12000Hz, default 12000Hz) - Filter cutoff - Examples: - Value = 20Hz: Closed - Value = 12000Hz: Open

ALGORITHM (Chaos / Wide / Pure, default Pure) - FM routing preset — selects how the two operators are connected - Chaos: Cross-modulation between both operators for unstable, evolving textures - Wide: Parallel operator topology for broad, layered sound - Pure: Standard FM (operator 2 modulates operator 1) for classic clean FM synthesis OCTAVE MODE (Sub Oct / Bypass / Upper Oct, default Bypass) - Octave mode - Examples: - Value = Sub Oct: Lower - Value = Upper Oct: Higher

FILTER MODE (LP / BP / HP, default LP) - Filter mode - Examples: - Value = LP: Low-pass - Value = HP: High-pass
