I just launched a new rack extension in the RE shop. It's a probability drum step sequencer. It's like the step sequencer in Redrum, but instead of 16 buttons that are always on or always off, there are 16 dials where you can set the probabilities of drums being triggered.
The RE is here: http://shop.propellerheads.se/produc...-drum-trigger/
There are two videos to help explain what it is and how to use it. And it's 9 bucks.
Let me know if you have any questions, or thoughts on how to use it and improve on it.
