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.

<andlabs> context?
<cr1901_modern> https://en.wikipedia.org/wiki/Atari_AMY Linked tweet is a prototype chip
<ValleyBell> The instrument loader on the CM-32P is interesting: It explicitly checks whether or not the instrument name consists only of spaces and if so, it explicitly mutes the channel.
<andlabs> oh
<andlabs> "The technology was later sold, but when the new owners started to introduce it as a professional synthesizer, Atari sued, and work on the project ended. "
<andlabs> um
<andlabs> did atari not know what "sold" means
<andlabs> or were they afraid because Sight & Sound was a Commodore hardware/software mnaufacturer
<Sarayan> depends on the sale conditions, if there was any
<cr1901_modern> I am curious what it sounds like, if the AMY chip is anything like "POKEY on steroids"
<ValleyBell> I'll leave the sound chip and DSP emulation up to you.
<ValleyBell> I did include a list of sound chip registers I figured out. (line 480)
<ValleyBell> Also interesting: Apparently panning is done by the DSP and not the sound chip.
<ValleyBell> There are also a few interrupts that are not firing and deadlocking the firmware.
<Lord_Nightmare> ValleyBell: for the cm32p driver, do you have pcb pics of the inside of the cm32p? the ROM names need fleshing out
