OK, the new ECS offers new graphics modes, better blitter, etc. BUT: the four sound channels need some attention too. If you use them as real stereo, you only have two. The Archimedes and Atari ST-E (is that spelled ok?) will have eight. In Europe, (70% sales), sound is very imporant attribute. People like demos with good music, and also some composing/converting on their own. This last one is sometimes the problem. If I have some synthesizers/ keyboards I can make a nice loop and digitize that, but if you don't have them you need standard instruments, and run out of channels very fast. Eight channels for the Amiga too! Maybe, these can be stereo too by assigning some value (-127 left, 0 both 127 right and all integers in between). Shields ON! I am not an electronics expert. I do not know about reserved bytes is the amiga audio.device, I do not know sound chip internals. Shields OFF!

I am certain that you do not need any more than 2 high quality channels. The rest can be done is software. Proof: Remember the RadioShack Color Computer. It has a single 6bit d to a converter that can be connected to the audio output. There are program for it that support 4 or more channels of sound. The trick is that you just average together all of your sound data before playing it. With some clever software using one channel as an AM for another channel on the Amiga, it should be able to make pseudo 8 channels sound pretty good. REAL NAME: Joe Porkka jap@frith.cl.msu.edu

You Amiga people have the Video Toaster, we Atari people have the "enhanced ST". Don't bet anything you value on the availability, capability, pricing, color, dimensions, etc etc of either until you own one. -- >>> "Aaiiyeeeee!

Why do you need 8 hardware channels. If you are inclined to have more of them, just add the wave forms. (Better yet, attach the existing channels end to end, and use the second to modify the envelope of the first. The actual hardware just adds the channels in analog. Since they represent a direct translation from the digital wave forms, you should be able to get better sound by adding them in software. That way, they also take up less space. (2 tracks versus 8. Naturally it would be harder to add instruments in real-time, though you could blit two instruments together at a time into a pad area before playing them. >Shields ON! >I am not an electronics expert.
