Hi All, Just came across this bit of code in STK's ModalBar class which should work well with the mode opcode. (If you're a blue user, these values should work with the "Reson 6 - Percussion" and "Mode 6 - Percussion" instruments from blueShare. though would need to modify them to accept fixed frequency modes). Thanks, steven // Presets: // First line: relative modal frequencies (negative number is // a fixed mode that doesn't scale with frequency // Second line: resonances of the modes // Third line: mode volumes // Fourth line: stickHardness, strikePosition, and direct stick // gain (mixed directly into the output static StkFloat presets[9][4][4] = { {{1.0, 3.99, 10.65, -2443}, // Marimba {0.9996, 0.9994, 0.9994, 0.999}, {0.04, 0.01, 0.01, 0.008}, {0.429688, 0.445312, 0.093750}}, {{1.0, 2.01, 3.9, 14.37}, // Vibraphone {0.99995, 0.99991, 0.99992, 0.9999}, {0.025, 0.015, 0.015, 0.015 }, {0.390625,0.570312,0.078125}}, {{1.0, 4.08, 6.669, -3725.0}, // Agogo {0.999, 0.999, 0.999, 0.999}, {0.06, 0.05, 0.03, 0.02}, {0.609375,0.359375,0.140625}}, {{1.0, 2.777, 7.378, 15.377}, // Wood1 {0.996, 0.994, 0.994, 0.99}, {0.04, 0.01, 0.01, 0.008}, {0.460938,0.375000,0.046875}}, {{1.0, 2.777, 7.378, 15.377}, // Reso {0.99996, 0.99994, 0.99994, 0.9999}, {0.02, 0.005, 0.005, 0.004}, {0.453125,0.250000,0.101562}}, {{1.0, 1.777, 2.378, 3.377}, // Wood2 {0.996, 0.994, 0.994, 0.99}, {0.04, 0.01, 0.01, 0.008}, {0.312500,0.445312,0.109375}}, {{1.0, 1.004, 1.013, 2.377}, // Beats {0.9999, 0.9999, 0.9999, 0.999}, {0.02, 0.005, 0.005, 0.004}, {0.398438,0.296875,0.070312}}, {{1.0, 4.0, -1320.0, -3960.0}, // 2Fix {0.9996, 0.999, 0.9994, 0.999}, {0.04, 0.01, 0.01, 0.008}, {0.453125,0.453125,0.070312}}, {{1.0, 1.217, 1.475, 1.729}, // Clump {0.999, 0.999, 0.999, 0.999}, {0.03, 0.03, 0.03, 0.03 }, {0.390625,0.570312,0.078125}}, };
