Having recently divested myself of my last vintage drum machine (a Roland TR-55, now on sale at CONTROL in Brooklyn), I decided to add this handly little (4hp) Eurorack module to my system. It's really quite a wonder considering its size and the eight (bass drum, low tom, high tom, snare drum, wood block, hand clap, closed hi-hat, open hi-hat) analogue drum sounds it faithfully produces with the help of clock source or sequencer. Delptronics has produced a winner here, and I can't wait to check this out with my Make Noise Pressure Points/Brains combo. BTW, an expander is promised, so stand by for more percussive fun from the "little drummer boy" module. Please be aware that this module requires a +5v connection for use in your rack or powered case.
