I use Numerology and I bought BSP as a replacement given it does almost everything I use Numerology for.
One thing I love about Numerology is its Generative options, one of which creates a random sequence based on a style. For example Berlin-school. Press the button and it REPLACES the sequence notes with notes based on that style, pitch quantise is all obeyed. If I like what I hear, I continue to play with it and I can save it. The random notes are created only once when you press the button.
BSP's probability is constantly changing notes and I cant save something I like.
