Okay, I'm getting there! How about, in terms of memory, if I whack in an 'Amiga A600/A1200 2.5’’ IDE Hard Drive - 2160MB (2.16GB)' - as I've heard about. Only about £10. Of course I then need an A600 or A1200 - but as they are cheap, I don't mind as much. more......
An A1200 with a hard drive is a much better starting position:
You'll start with at least version 3.0 of the operating system which opens up more software options.
The A1200 comes with a 2MB of RAM (called Chip RAM as it is shared between the CPU and the sound / graphics chips) as opposed to the 0.5MB or 1MB an A500 typically has. Chip RAM is important for many older music packages as this is where the sound samples are held during music playback. Note that OctaMED SoundStudio is not restricted to using only Chip RAM for sound samples, you can use as much memory as you have fitted. And speaking of memory...
The CPU in the stock A1200 is 2-3x faster than the one in the stock A500. Just adding more memory to the A1200 (via the trapdoor slot) can double that too. The reason for this is that in a Chip RAM only A1200, the CPU has to share access to the memory with the sound and graphics chips. This basically slows the CPU down since it has to wait for the graphics/sound chips to have their share, which is usually 50% of the time (or more). So just adding 4MB of memory to the trapdoor not only gives you 3x more memory than you had to start with but can double the performance to :-)
However, it doesn't stop there. Many cards exist for the trapdoor slot that add not only more memory, but an even faster CPU to start with. If you get a 50MHz 68030, you can happily use OctaMED soundstudio with 16 sound channels at once and have enough CPU power left to comfortably use the system. With a 25MHz 68040 I've had 32 sound channels without problems, and that's good for making some noise :-D
Also, a faster CPU in your A1200 with a hard drive gives you more scope for mixing your finished many-channel song to hard drive for, perhaps burning to a CD later? :-)
