AY riders

Why does no mention exist on this page of groups who have made music and even albums with the AY chip? e.g. the (AY Riders) have actually held a successful concert (in Poland). —The preceding unsigned comment was added by Phase Theory (talk • contribs) 2006-04-30 00:41 (UTC).

Presumably because it's an article about the chip, not the people who use it or the music made with it. Or simply because nobody has cared enough to add it. There's already links to examples of music, a link to them or a "See also" entry wouldn't be out of place, I suppose, so go ahead. Or better yet, link to Chiptune which is concerned with the music (and not the hardware) and has tons of composer links.

== Creative uses == the music made with it? Anyway, I will go ahead, and I will link to Chiptune as well. CMIIW 19:16, 23 May 2006 (UTC)[reply]

I'd say "creative uses" rather means "creative tricks and hacks", doing things that were perhaps never intended by its designers, and not "people being creative making music".

Saying that some people made music with it is a bit of a "well, duh" statement, given that it was actually made to do just that. :-) (and especially when the section starts with "some people made really advanced music, on the ST and the Amstrad CPC")

A small music links section perhaps? For having examples of music, we could do worse than pointing people to, say, AY Riders and YM Rockerz. I'll make the changes if you don't mind.

The ZX Spectrum+ didn't have the sound chip but the 128, the +2 and the +3 did.

And the initial 16k and 48k ZX Spectrums certainly didn't have this chip in them.

The 8910 doesn't have an ADSR Envelope

The article links to the ADSR Envelope article, and suggests that the 8910 chip has an ADSR Envelope. While it does have some crude form of envelope generation, it is not an ADSR Envelope.

errors in article

"Some programs have been created specifically for writing AY chip music, such as SoundTracker." => it's not true, the SoundTracker program (for unix) is for creating MOD (sample) music. Vortex Tracker http://bulba.untergrund.net/vortex_e.htm does this instead.

There are many trackers for different systems named SoundTracker. One of them is for ZX Spectrum, first AY tracker for the platform. http://www.worldofspectrum.org/infoseekid.cgi?id=0012090 —Preceding unsigned comment added by 95.24.151.61 (talk) 19:56, 17 December 2008 (UTC)[reply]

Other programs to write music for AY-3-8910 are: MaxYMizer, ppMCK, and VGMCK (which also supports AY8930 extended mode, although no existing software will play music written for AY8930 extended mode). FamiTracker does not currently support AY8910, although a future version might support this. Other than MaxYMizer, these are not meant specifically for AY-3-8910. There may even be more that I have forgotten or don't know about. --Zzo38 (talk) 00:23, 8 May 2013 (UTC)[reply]

the Uses paragraph needs reworking

It first starts off with digital samples audio, which is NOT the main use for the chip.

Additionally the article a little confusing about sample sounds via rudimetary D/A conversion. It claims the chip has an OR function but does not state precisely enought that's to mix the noise with the tone *per channel*. This means in fact 3 times an OR. But this information is not really in relation with producing digital sound and should be put into the missing section about producing square wave sounds.

There is a data sheet available online here: http://soundprogramming.net/electronics_reference/sound_chips Gunstick (talk) 21:02, 31 July 2009 (UTC)[reply]

regarding the clock input

An edit made on 00:59, 5 February 2021‎ by user Gjpiloz changed the description of the "Variants" section decribing the YMZ284 in the sentence: "It's basically YMZ294 without the 4/6 MHz selection pin and the /TEST pin."

Which had previously read "4/8 MHz."

I'm not aware of any reference to 6 MHz input clocks or a two-thirds divider on any of the YM2149 variants, and the existing YM2149 datasheet simply points to the one half divider function when the SEL pin is pulled low. (the latter feature is correctly listed in the YM2149 description) That said, the previous 4/8 MHz description is also inaccurate as the rated operational frequency of the YM2149 is 0.5 to 2 MHz (external clock of 1 to 4 MHz with SEL pulled low), so saying "2/4 MHz" selection pin would be more accurate, but given the chip doesn't need to run at its maximum rated frequency, this still isn't best information.

Simply saying the frequency divider (or frequency halving) selection pin, or "clock frequency selection pin" was omitted from the YMZ284 would be more proper.
