ChanServ changed the topic of ##yamahasynths to: Channel dedicated to questions and discussion of Yamaha FM Synthesizer internals and corresponding REing. Discussion of synthesis methods similar to the Yamaha line of chips, Sound Blasters + clones, PCM chips like RF5C68, and CD theory of operation are also on-topic.

<cr1901_modern> Thanks for stopping by brezza_dsa, I'm actually around now lol
<brezza_dsa> hi thank you for informing me about this irc channel.
<cr1901_modern> You're welcome! Thank Xyz39808 for telling me about you lol

<Xyz39808> o/
<cr1901_modern> brezza_dsa: Tbh, I've been out of doing Yamaha stuff for a while now due to sickness, but I found this envelope damping research and graphs pretty cool: https://github.com/digital-sound-antiques/emu2413/wiki/Envelope-Damp-and-KeyOn-Noise
<cr1901_modern> 10ms... definitely in line w/ Yamaha's general vagueness
<brezza_dsa> oh, i hope you get well now. thank you for reading the article. I think recent ym2413 emulators already emulate this behaviour.
<cr1901_modern> I'm doing much better now, tyvm. I'll ask nukeykt about it too when he's around. The noise looks like a hardware bug.
<cr1901_modern> I wonder if Yamaha realized it was a hardware bug after silicon, and decided to make it a "feature"
<Xyz39808> have you asked valley bell to add emu2413 changes to official in_vgm?
<Xyz39808> he is also in this room
<cr1901_modern> cc: ValleyBell (should be morning where he is)
<cr1901_modern> One of the CMOS 2413s had its instrument table read out recently, and it's likely to be the same as the NMOS version
<brezza_dsa> i personally feel DP is buggy but ym2413 is cost-reduced chip so it may be "feature".
<Xyz39808> also, cr, did you see plogue gave out some other opll related patch sets? https://twitter.com/plgDavid/status/1214249251166937095
<Xyz39808> ear copies, ofc
<brezza_dsa> I'm not sure DP behaves like this on all lot and variation of ym2413 chips. I only tested with YM2413B.
<cr1901_modern> So that's... 3 copies I know of... nukeykt, Dave's and dsa's
<cr1901_modern> kevtris did vrc7 by ear a long time ago, but Idk if he ever did ym2413
<cr1901_modern> I would like to get YM2413 support into ADLPLug (MIDI frontend for the Yamaha chips) w/ all the new discoveries, but no energy: https://github.com/jpcima/ADLplug

<cr1901_modern> brezza_dsa: Is DSA a single person or multiple people?
<brezza_dsa> it's secret :-D
<cr1901_modern> I see :)
<Xyz39808> :o
<brezza_dsa> joking, currently single:)
* cr1901_modern is single too and not looki- oh wait, wrong single
<brezza_dsa> lol

<cr1901_modern> brezza_dsa: Btw, I don't work on this _anywhere_ as much as I should, but I also have this: https://github.com/cr1901/ym2151-decap
<brezza_dsa> cr1901_modern Great. I will check it :)
<brezza_dsa> cr1901_modern tbh I myself have no skill to REing the circuit from the electron micrograph. Simply admired!
<cr1901_modern> brezza_dsa: I appreciate that. I have a tutorial if you wish to get started yourself: https://www.wdj-consulting.com/blog/nmos-sample/
<cr1901_modern> "Blame" Lord_Nightmare for getting me started with this
<brezza_dsa> cr1901_modern thx!
<brezza_dsa> wow obtaining a picture from a digital camera and a normal microscope... very cool. i thought the electron microscope is required.
<cr1901_modern> Idk who provided the picture, but it was not me.

<peachu> absolute longshot here but does anyone know anything about the playcards / graphics cards?

<ValleyBell> brezza_dsa: Thanks for joining and for all the hard work! It's great to see you here.
<KitsuWhooa> <cr1901_modern> brezza_dsa: I appreciate that. I have a tutorial if you wish to get started yourself: https://www.wdj-consulting.com/blog/nmos-sample/ <-- that's awesome
<KitsuWhooa> maybe one day I'll get the saturn drive protection IC decapped and dump the rom
* KitsuWhooa has that itch to scratch
<KitsuWhooa> now if only microscopes didn't cost absurd amounts of money
<brezza_dsa> ValleyBell nice to see you. I'm very grateful for vgmplay and related works, and thank you for using emu2413.
<brezza_dsa> ValleyBell I'm testing emu2413 update for vgmplay. If you are interested, I will create a pull request after test finishes. https://github.com/digital-sound-antiques/vgmplay/tree/update-emu2413
<KitsuWhooa> nice
<ValleyBell> sure, that would be nice
<brezza_dsa> :)
<cr1901_modern> KitsuWhooa: rqou already did that, although they didn't resort to decap for that :P
* cr1901_modern goes to bed- night everyone
<KitsuWhooa> no rom was released, was there?
<KitsuWhooa> also it was a different IC IIRC
<KitsuWhooa> night :p
<cr1901_modern> Maybe if you ask nicely, rqou can point you in the direction of the ROM... that's all I'll say :)
<KitsuWhooa> eh
