values produce lower cutoff frequencies. "0" level values produce the normal cutoff frequency as determined by the cutoff parameter (See "Cutoff" on page 65). RS (Rate scaling) Range: -7 ... +7 Controls: [CS2], [-1] [+1], Dial Allows the overall cutoff envelope generator rate for the selected filter to be varied across the entire pitch range (i.e. keyboard range). This function is only available if the "CTRL" parameter (page 68) is set to "EG." Plus ("+") settings produce a longer overall envelope time for the low notes and a shorter envelope time for the high notes. The maximum "+7" setting produces the greatest envelope length variation across the pitch range. Minus ("-") settings produce the opposite effect - a shorter low-note envelope and longer high-note envelope. A setting of "+0" results in no envelope length variation. R1 ... R4, RR1, RR2 (Rates 1 ... 4, Release rates 1 & 2) Range: 0 ... 63 Controls: [CS3] ... [CS8], [-1] [+1], Dial These parameters work in conjunction with the level parameters described above to determine the "shape" of the cutoff envelope generator for the selected filter. This function is only available if the "CTRL" parameter (page 68) is set to "EG." The "Rate" parameters work in the same way as the amplitude and pitch envelope generator rate parameters: a setting of "63" produces the fastest (almost instantaneous) rate between levels, while the minimum setting of "0" produces the slowest change. The filter envelope begins at L0 (Level 0), moves to L1 (Level 1) at a rate determined by the setting of R1, then to L2 (Level 2) at R2 (Rate 2), then to L3 (Level 3) at R3 (Rate 3), and then to L4 (Level 4) at R4 (Rate 4). The cutoff stays at L4 until the key is released, and then moves to RL1 (Release Level 1) at the rate determined by RR1 (Release Rate 1), and finally to RL2 (Release Level 2) at RR2 (Release Rate 2).
