1. K1600 MIDI Converter Hardware Version C D Firmware Version 1 0x User Manual February 16 2011 Kilpatrick Audio a i K1600 MIDI Converter 2p Introduction The K1600 MIDI Converter is a versatile bridge between MIDI equipment and analog modules Its outputs are designed to interface with many types of modules and the method of control can be adapted to suit your needs By using a MIDI learning approach to programming MIDI messages can be used to assign the outputs quickly The CV and gate outputs specifically allow different modes of operation for pitch and gate control even supporting polyphony By using multiple K1600 modules the MIDI signal can be daisy chained between modules This not only expands the total number of outputs but also allows polyphonic control of more than two voices In this mode the modules work together to assign voices to up to 16 CV gate output pairs Features C Eurorack 3U form factor 12HP width MIDI to CV gate trigger and clock converter Provides MIDI expansion for other Kilpatrick Audio modules MIDI soft thru for daisy chaining multiple units Quick programming with MIDI learn function Multi channel and split keyboard support for independent control of different outputs Polyphonic CV gate output duophonic support with a single K1600 Polyphonic mode with 4 6 8 etc voices using multiple K1600s CV pitch bend support Four drum trigger outputs
