I/O Expansion for Five12 Vector Sequencer
This module plugs directly into the Vector Sequencer via two ribbon cables and adds a significant amount of additional I/O:
Four sets of 'voice outputs', each with Pitch, Gate and Velocity signals. The Pitch DACs use high-quality 16-bit converters with a voltage range of -3V to +7V. The Velocity DACs are also high quality 12 bit converters with adjustable output ranges: +/- 5V, +/- 2.5V, 0-5V.
Eight trigger outputs, six of which can also run as inputs. Trigger outs are handy for triggering drums or generating clock signals. In input mode, these triggers can be used to reset or manually step any of the Vector's eight sequence parts.
MIDI In and Out on 5-pin DIN jacks.
DIN Sync on 5-pin DIN jacks.
The 44mm mounting depth includes ribbon cable connections to the Vector Sequencer.
These merchants probably sell this module. Huh?
