""Rare italian early 'groovebox'. It combines a analog preset drum machine with an analog auto accompaniment unit.

Features:
- drum machine with 12 presets and independant volume control
- bass section with 2 sounds: bass or brass, and independant volume control
- chords section with 2 sounds (one very nice sweeping through a analog filter) and independant volume controls
- arp section with 2 sounds with control over decay and independant volume control
- one finger chord. There is also a pedal input on the back to switch between Major and Minor mode
- memory feature: hold the notes you just played
- key start feature: triggers all the sounds only when key is pressed
- tempo, global volume and global pitch control

Unit has a permanently attached 1 octave DIY keyboard and it is working fine with small minor issues:

- the "walking bass" feature doesn't seem to work as it should. I would except it to do some arpeggio on the bass sound but it doesn't. Also the led doesn't work on that switch so this may corroborate the theory

- the Arp section sometimes has some kind of tuning hesitation that resolves by itself after a few seconds. It happens when you move a slider but not always. You can hear it on the demo I made."
