Hmmm! It seems doom sounds nothing like Keen4.
i recorded the file below
0:00 to 2:00= cs2740( real opl3)
2:00 to 4:00 = cs4180
4:00 to 5:45 = Crystal cs4236b
Finally maybe Keen4 is not a good example.
Doom show DIFFERENCE in FM music quality
between Cs2740 and cs4180. I think CS2740 beat cs4180 even easily and sounds like the youtube genuine yamaha opl3 link that you gave me earlier in another topic.
CS2740 sounds like a genuine yamaha opl3 in Doom. Ct4180 doesnt sound like a genuine yamaha opl3 to me. Its sound better than Ct2970 with his CQM tough. Maybe ct4280 has a custom CQM or another FM but i dont believe anymore its a real genuine yamaha opl3. Crystal cs4236b sound worse than both sb16 cards, but still not bad at all, indeed very good. Crystal cs4236b sounds better than cs2970 and better than es1869f to me.
But please judge for yourself and tell me your opinion and answers. Thanks guys !
(By the way, with the help of my doom uploaded file below, please tell me if you find that my SB16 CT2740 sounds like a real genuine Yamaha opl3 FM and like a genuine Sound Blaster 16 sound card, just to be 100% sure, thanks for answer. Im not a audiophile expert.)

Ok for keen 4 SB16 ct2740+opl3 win easily vs crystal cs4236b.
But for Jazz Jackrabbit 1st stage:
(i think its digital music and no fm)
Crystal cs4236b wins. Music quality is better than SB16 ct2740 sound card. Before you ask, i already patched Jazz MDRV004D.MUS for DSP 4.0 and SB16.
The difference is not big between each sound card, but Crystal cs4236b sounds better, better quality. Its like music is 44khz for crystal vs 22khz for SB16 ct2740. ( Before i patched Jazz, SB16 music sounds like 8khz LoL!)
( i already installed the disk version of dos driver for SB16. I didnt change any parameter yet. And i didnt move any jumper on the card. I just played with the volume rocker. By the way i heard no noise with this sb16 ct2740. )
Do you have any idea to get Jazz music with SB16 ct2740 good as the CS4236b ?
Thanks for answer. I cant believe Sound Blaster 16 cant beat Crystal in digital music quality. 😀
Edit: i compare them several times. The big difference is the music CLARITY. Music with Crystal cs4236b has much better Clarity than SB16 ct2740. Both have the same setup.exe parameters in Jazz. For Both sound card i choose Sound Blaster 16 with A220 I5 D1.
Thanks for answer or help.
