This was my only BD module for a few months. I have read a few reviews from people who don't like it in comparison to the original 909, that its not punchy enough or such.
I really like the BD909.
As it has a very wide sonic character it lends itself very well to further modulation and mangling. Saturating or overdriving it with a VCA gives very varied results. If said VCA is controled by an snappy envelope in time with the beat you really start getting somewhere.
I feel it really shines when paired with a resonant filter, hp lp bp all give different results.
I like the dry sound of it also, but if you have not fallen in love with the BD909 try treating in like an oscillator and not an end of the line module.
