Hi,
In fluid 1.1.6, fluid_voice.c, line 1010,
case GEN_VOLENVDECAY: /* SF2.01 section 8.1.3 # 36 */
case GEN_VOLENVSUSTAIN: /* SF2.01 section 8.1.3 # 37 */
case GEN_KEYTOVOLENVDECAY: /* SF2.01 section 8.1.3 # 40 */
y = 1.0f - 0.001f * _GEN(voice, GEN_VOLENVSUSTAIN);
fluid_clip(y, 0.0f, 1.0f);
count = calculate_hold_decay_buffers(voice, GEN_VOLENVDECAY, GEN_KEYTOVOLENVDECAY, 1); /* 1 for decay */
fluid_voice_update_volenv(voice, FLUID_VOICE_ENVDECAY,
count, 1.0f, count ? -1.0f / count : 0.0f, y, 2.0f);
break;
From the souce code, the sustain level is directly read out from GEN as a float cofficient. But according to the SF2.01 spec section 8.1.3, the value stored in GEN#37 is in unit of centibels.
Could anyone please check if this is a bug here, or my mis-understanding? Thanks
