This is a drum machine that consist of two main components. First is the 4 channel step sequencer with 8 memory banks and also the ability to load from a preset bank so you can retain patterns between saves. Thanks to @JDRaoul for his sequencers (http://forum.audulus.com/discussion/379/sequencer-modules#Item_6) as I have used some of his (genius!) techniques in this patch.
The second part is a drum synthesiser repeated 4 times (one for each channel). This is designed to generate a wide range of drum sounds. Have a play around with it, it's fairly self explanatory, CPU usage is quite good on my iPad4 considering what it does.
@Taylor if you look at this can you look at the file size, it jumped from around 1mb to 3mb in the last few saves.. Not sure why as the patch didn't increase in nodes much.
Cheers
