opnb?
OPNB
OPNA's ADPCM is also needed, because for PCM sampling, I need to have precise frequency settings to make the pitch accurate.
yコマンドでもダメですか?
So which y command should I use? yn1, n2 are right, but I don't know what should be filled in n1 and n2. What is the register number of ADPCM-B?
「YM2610 application manual」で検索するとそこらへんの情報は見つかります... アドレスはPort0の$10~$1Fのようですね...
或いはデチューンコマンドで音程をずらしてみるとか。
The detuning command EXn can only be used for FM channels.
△N = ( f ÷ 55.5 KHz ) × 65536
19 | Delta-N lower 8 bits | Delta-N (LSB) 1A | Delta-N upper 8 bits | Delta-N (MSB)
'T19 T1 p3 @3 y$19,$6a y$1A,$cb This only defines the frequency as 44100hz, but there is no sound. How should I excite the note?
デチューンコマンドはDです。
発音するためのシーケンスもマニュアルに載ってますけど... yコマンドで済ますのはちょっと現実的じゃないかな...orz

ok
For example, I need the sound between o6g and o6g+, that is, the sound between semitones. Is it possible to directly define the frequency to?
