- Midi out
- signal out (it disables internal speakers)

Power supply external 9V DC +)- polarity or 6 X 1.5V batteries.

rock, salsa, march, country, dixie, pop, waltz, shuffle, afro, rhumba, disco, pola, chacha, ballads and ondo .... ondo? HEAR a preset

SEQUENCER no possible edit but some little variation using the INTRO and FILL functions.
Internal tempo range from 32 to 280 BPM and no possible external clock.

HEAR another preset

MIDI the pads output 16 levels of velocity, the implementation is really limited: do not expect a sophisticated Midi controller.

MODIFICATION

DD5 CIRCUIT BENDING like many cheap drum toys, the DD5 is one of the most appreciated victim for circuit bending. Seems that PCM are stored in a IC XE312A0 if you want to try out (at your own risk!) left pic: Battered BENT DD5
