+      The synth core supports:
+
+      - Arbitrary amounts of polyphony
+      - 8 operators
+      - No fixed "algorithms"
+      - Arbitrary modulation, every operator can modulate any other operator, even itself
+      - Arbitrary carrier selection, every operator can be a carrier
+      - Sine LFO, separate LFO per voice, modulates amplitude and frequency of operators
+      - Envelope per operator
+      - Carrier stereo panning
+      - Velocity sensitivity per operator
+      - Mod wheel sensitivity per operator
+      - Pitch bend
+      - Keyboard scaling
+      - Sustain, sustained keys can overlap each other for a very rich sound
+      - Full floating point implementation optimized for SIMD
+      - Hard real-time constraints
