YM musics using envelopes to test YM emulator

Postby aag » Thu Jun 09, 2011 7:29 pm

Hi

Just wondering if there are any YM files that actually use the envelope genorator to use variable volumes, rather than fixed (registers 8,9,10, 5th bit = 1).

I'm in the processes of using MikeJ YM VHDL "linear mix" as a basis for a ym chip emulator - and am using .yms to test my code. (Just to see if using vhdl sources can be used to derive code in traditional programming languages).

So far, I haven't managed to find any YM's which use the envelope for the volumes.

Thanks


If anyone is interetsed - theres a zip'ed wav with the 1s 20 seconds of xenon produced by my app.

Hi,

I've not done too much YM tunes yet, but would recommend you look at the YM Rockerz SNDH archive, @ creamhq.de (i think!)

Only about every other tune there is. The buzzer sound is done using a high frequency volume envelope.
Kludge power since 1976.

Thats what I thought - but what I've tried (xenon/eliminator) don't seem to? I guess I'll check my ym loading against st-sound, as I'm probably doing something wrong.

Most tunes in commercial games don't use the buzzer sound. You should look more into the demoscene productions for more variety on the usage of the YM chip. SNDH archive is your best help with that: http://sndh.atari.org.

Thanks for the sample files (there was a bug with my ym loading.) Once I've got the envelopes sorted via YM then I'll take a look at sndh.
