I'm sure they did, that I first realised it could be arbitrarily patched on reading the SysEx specs, and that I have a copy of them saved somewhere... but as yet, I have no idea where it is. Which is annoying me quite considerably. On the other hand, Yamaha make almost all their manuals available for free online, and I'm sure it can be found there. ...And I just found it again. The filename is 'sy99e2.pdf', the MIDI implementation chart, and it's all in table 1-7 - but cunningly, not everything is specified, so some experimentation would have to be done to find out exactly what the details are. However, by the looks of it, each operator can select two of 10 input modulators (prior operators, 3 registers, noise and AWM - but which is which is unspecified!), subject each input and its own output to 8 levels of attenuation, and send its output to one of 3 intermediate registers (accumulators?) or the sound output (although that's not fully explained; the output accumulator has two inputs, and the first can select from two sources... *shrug*). Unfortunately, that's as far as I can go, because despite my best efforts I don't have an SY77, TG77 or SY99. -- dupswapdrop -- the music-dsp mailing list and website: subscription info, FAQ, source code archive, list archive, book reviews, dsp links http://music.columbia.edu/cmc/music-dsp http://music.columbia.edu/mailman/listinfo/music-dsp
