I've been working on the little drum sequencer module. 

It now has the following abilities:

• 16 Patterns of 16 steps
• 8 Tracks
• Each track can have a different drum instrument
• Track mute control
• Internal clock with variable BPM
• Start / stop button

Some things that are still missing:

• Show drum instrument name instead of number
• Saving / loading of sequenced
• Copy / pase of patterns and tracks
• Track volume slider
• MIDI clock source
• Playout button icons and extra functions such as repeat pattern
• Maybe an overview of all 8 tracks of a pattern?
• The module should be able to run in the background
