...you asked for this, sweaty.
FAVORITE 2ND GEN CHIP
this one's obvious, since the intellivision did have it. the ay-3-891x series of chips are, in the right hands and with the right knowledge, super versatile and somewhat on the level of the c64's sid? i still need to study that chip and use it more often. close runner up is the sn7, which the colecovision had
FAVORITE 3RD GEN CHIP
honestly, i don't think many can really take the cake much like the vrc7 can when it's coupled with the 2a03. i know, sorta cheating by putting these two together, but it's the only way the former can really operate so i have no choice! if we're going with single chips only, though, i'll keep the 2a03 since it operates on its lonesome. the limits of the 2a03 are enough for me to manage, but putting it together with the vrc7 makes it into a POWERHOUSE. you have a pretty okay array of prebuilt fm patches to supplement the pretty anemic 2a03 pulses and triangle and a universal custom patch to do ANYTHING with. that alone makes it the ultimate expansion combo. close second is (again) the sn7 if we're doing single chips, and the sn7 + fm sound module if we're doing combos.
FAVORITE 4TH GEN CHIP
the ym2612, no question. this chip is a classic and trying to explain how awesome it is would be like reciting the dictionary at this point. absolutely powerful on its own, and an absolute dream to work with combined with the sn7 and sega psg. it's no wonder sega had their fair share of iconic game osts back then. runner up would probably be the wavetable sound chip the pc-engine had
FAVORITE IBM PC SOUNDCARD
you come over to my hobbit home in the middle of the mythical woods, wisconsin. you ask me, "hey lumby! i'm gonna play the secret of monkey island on my 386 tower and i need a soundcard to plug in there! what do you recommend?" before you finish that last question, i am immediately in your face and screaming ADLIB ADLIB ADLIB ADLIB ADLIB before immediately passing out on the floor. i don't think i need to elaborate on that opinion. second favorite would probably be either lapc-1/mt-32 or gravis ultrasound
FAVORITE PC CHIP PRE-1982
difficult decision, but the atari pokey honestly has a lot of potential when it comes to music. it's very versatile for the time and has a ton of tones types you can combine to create different instruments with. the ti-99 had a variant of the sn7 in it as well, making that my runner up
FAVORITE PC CHIP 1982-1984
probably an obvious choice, but i have to go with the sid. 3 channel synthesizer with a filter? sign me the fuck up and give me two while you're at it!! wickedly versatile and lush when doubled up. runner up is the ay-3-891x/ym2149f series, since those got popular use in this generation of computers as well.
FAVORITE PC CHIP 1985-1990
the commodore paula is also probably an obvious choice as well. this is the chip that started the tracking phenomenon, after all, and it alongside deluxe paint made the amiga a veritable creative powerhouse back in the 80s and 90s. as well, though, it's pretty damn versitile for a non-ibm sound chip and has led to quite a few of my favorite tracker tracks
FAVORITE BEEPER
the zx spectrum goes fucking sicko mode when it comes to beeper music. there are DOZENS of beeper engines out there, a lot of them being SHOCKINGLY amazing from the wavetable-based wtbeep and fluidcore to the old-school classics octode and tritone. legit, you can present 10 random zx beeper songs and all of them could sound completely different. runner up is the ibm pc's beeper
i could go into which chips are my favorite in terms of what type they are, but then this post would go on forever. i think one and a third of my screen height is good enough
