- most people would use it as a midi module and never bother reading the ~90 pages of manual (which is nice btw)
- more units might have been produced
- acid music as you know it wouldn't have happened or at least wouldn't have sounded the way it did
- 2nd-hand prices now wouldn't have been that high
yeah, it surely is possible to "learn" those rules which the sequencer forces on the synth, and apply them when you sequence via a piano-roll in your DAW
i certainly can, i'm sure there are other people who can too
but:
- the majority of people don't know, nor care to know, as they think the special sound comes immediately, from the special filter
- the piano-roll is too different
so if you know exactly what pattern you wanna program, and you know these "rules" - sure you can use the piano-roll
however, once you want to modify this pattern or experiment (hunting for happy accidents) you can see how the piano-roll becomes a pain
normal people would mess up the notes and break those rules and end up with something that doesn't sound like a 303 pattern
that's exactly where the sequencer comes to the rescue
it makes it easy to experiment with the patterns without breaking the rules, nor forcing you to understand them.. you only have to learn how to use it, just like you have to learn your DAW's sequencer
i wouldn't say VB-303 is the best soundwise, as it sounds more like my x0xb0x than a TB-303
maybe it's the best in the freeware world
the current commercial 303 emulations were made before VB-303, and CPU usage was a strong concern then (users always want great sound at near-zero cpu usage)
now i see recently a few commercial synths (not 303-related) (looking at KVR people's comments here) are finally pushing, daring to use more CPU than most people expected but bring great sound with it, that's very good, better oscillators, better filters, better modulation, better sound
so back to 303s.. this is not the end of the horizon, there are new things to come pretty soon
