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> Blarg, I was hoping to fill in the FM Theory page on SIpr0n, but my todo list in the afternoon kinda exploded as ppl got back to me (and I decided _today_ was a good day to wipe a machine and upgrade it. I should prob learn ansible...)
<cr1901_modern> (The self-feedback register in at least the OPM manual says the maximum phase offset is 4*pi... tbh, I have no idea how the Yamaha ppl got that number, and maybe mapping the Yamaha chip internals to the phase mod equation will help me answer that)
<cr1901_modern> Also, the YM2151 player I linked yesterday... it sold out already. :o
<cr1901_modern> I don't remember who asked but... the player plays s98, MDX, and VGM files
Stilett0-away is now known as Stilett0
<m4t> whoa that guys twitter is filled with cool stuff
<protosphere> Oh I remember seeing those kits last time I was there
<cr1901_modern> Who is kadenken?
<cr1901_modern> Or what*?
<andlabs> the ym2151 vgm player thing guy
<cr1901_modern> The ym2151 player thing is by g_yotuya
<cr1901_modern> (Unless I'm missing some sort of connection)
<andlabs> then IDK
<m4t> that might be their store
* m4t scrolled down their twitter feed
<cr1901_modern> ahhh... I think the ym2151 player person might be trying to get kadenken to sell their player?
<m4t> ¯\_(ツ)_/¯
<m4t> i assumed it was the same person who owned the store and made the boards
<m4t> prolly got it mixed up. cool store tho

<andlabs> "and many people find that software emulation..."
<andlabs> maybe if the software emulation wasn't primitive by comparison to other computers
<andlabs> onlyt he pre-OS X Macintosh is in a worse state
<cr1901_modern> I thought Rosetta was pretty good for its time

<andlabs> no I mean actual emulators

<emily> Rosetta is also distinct from the Classic environment of early OS X
<emily> (which had a name, I think, I just don't remember it)
<Sarayan> carbon?

<andlabs> it was called Classic
<andlabs> =P
<m4t> https://twitter.com/kadenken is the store's twitter
<m4t> that place looks so cool
<m4t> i would buy one of everything
<m4t> all we got here is...gamestop :(

<fseidel> Oh man, I saw that place a few months ago when I was in Japan
<fseidel> It's awesome!
<fseidel> they have a Yamaha FM chip gachapon
<cr1901_modern> Oh, that's the place with the gacha
<cr1901_modern> _that's_*
<fseidel> I got a YM2610
<fseidel> Was hoping for 2608, but it's luck of the draw
<cr1901_modern> I have a few YM2610s, but the power requirements are such that I don't feel comfortable powering from USB, so I haven't used them much
<cr1901_modern> (not to mention they require an external (D)RAM and use a weird DIP form factor)

<andlabs> oh that reminds me
<andlabs> using Eagle itself gives me much more useful BOMs
<andlabs> especially since a different file I have is the old binary format that kicad can't handle and pcb-rnd or whatever it was called doesn't parse the file correctly
<andlabs> maybe I will go through with that sfx sound expander clone, but I will need a YM3528 AND a YM2410 (the DAC)
<andlabs> (the binary-form eagle board is a different project not related to Yamaha sound except that it's related to Genesis)

* Sarayan pokes whitequark
<whitequark> Sarayan: hi!
<Sarayan> Hi you, how are you? And did you get the package? The post office tracker says you did
<Sarayan> (I don't really trust the post office tracker)
<whitequark> yes, I did! (I thought I already mentioned it here?)
<whitequark> I haven't even opened it tho, been even more busy than usual
<whitequark> hopefully soon
<Sarayan> No problem, this is excellent
<Sarayan> I must have missed your previous answer, I've been mostly off the internet lately

<andlabs> and now I know a partlist != a BOM
<andlabs> boo I need to make a mouser account to upload a BOM
<andlabs> same with newark
<andlabs> digikey doesn't like eagle's semicolon-separated values
<andlabs> arrow doesn't handle it properly
<andlabs> but it does parse the file at least
<andlabs> avnet isn't loading
<andlabs> okay I'm starting to think I'm misisng something
<andlabs> which doesn't help because I can't find the part numbers I'm getting
<andlabs> *which* 0.1uF capacitor is "C-EU050-024X044" with package "C050-024X044"?
<andlabs> *what* is "MA03-1"? the only thing this is saying is that it comes from the eagle library called "con-lstb"
futarisIRCcloud has joined ##yamahasynths
<m4t> male 3x1, prolly 0.1" pitch
<m4t> (guessing)
<andlabs> well I wound up buying a premade thing from a different product entirely
