QUBit Cascade Ratcheting Envelope generator, Sound Source, and VCA all in 10hp of space! The envelope can be AR, ASR, ADSR, and the attack and decay/release are voltage controllable. The VCA is normalled to the Envelope, but can also be used completely independently of the envelope. The sound sources are all the essential electronic drum machine basics; kick and hats.

This little module does a lot! I have another of these in my portable skiff, and I use it all the time. This particular module was in my 360hp studio rack, which sadly I am selling off bit by bit to get more room in my tiny cramped studio.
