Problems with the CGB Compatible Sound Envelope

## CGB Compatible Sound Envelope Problems

In this system, envelopes are created using hardware functions. For this reason, there are the following limitations.

(1) Attenuation of the volume makes linear, not exponential changes, so it sounds unnatural to the ear. (It sounds like the sound disappears too quickly.)

(2) During amplification and attenuation, volume adjustments (changes in volume, tremolo, etc.) cannot be made.
The volume adjustment level will work only at the following times.
1) When a voice (sound/song) starts.
2) When there is a shift from attack to decay.
3) When there is a sustained sound.
4) When a release starts.
(From the opposite perspective, the volume adjustment will work at these times, so it does not actually seem very restricted at all.)

(3) The range of possible settings for each envelope level (Attack, Decay, Release) is narrow and approximate. There are 7 stages, so it is really hard to get the tone color the way you want it. (In mks4agb.ini , the settings range from 0 to 99, but these are actually converted to 7 stages.)
