Decompile from asm: DseTrackEvent_SetupKeyBendLfoEnvelope 0x0207222C DseTrackEvent_UseKeyBendLfo 0x0207225C DseTrackEvent_SetupVolumeLfoEnvelope 0x02072504 DseTrackEvent_UseVolumeLfo 0x02072534 DseTrackEvent_SetupPanLfoEnvelope 0x02072720 DseTrackEvent_UsePanLfo 0x02072750 All six index struct dse_channel's existing lfo_settings[4], which sits at offset 0x74 with a 0x10 stride -- the stride the asm computes as ip lsl #4, and the offset another handler in this family loads directly as channel + 0x74. The three pairs address entries 0, 1 and 2, so key bend, volume and pan each own one lfo_settings slot. Within an entry the setters write +0xa and +0xc, which are msec_until_lfo_started and lfo_envelope_len_msec, and the Use handlers write +1 and +2, which are type and output_type. output_type is set to 1, 2 and 3 for key bend, volume and pan respectively, which is consistent with the slot each one uses; that is an observation about the constants, not something the bytes label. The Use handlers needed an explicit if/else rather than a ternary. Every conditional-expression spelling tried -- v ? N : 0, v == 0 ? 0 : N, !v ? 0 : N, and (v != 0) -- emits movne before moveq, where the target emits moveq before movne. The statement form reverses the pair and matches.
