Analog Ribbon Controller With Pitch Bend
AXE & RAZOR work together as an external expression controller for your Eurorack modular synthesizer.
AXE creates five control voltages from four touch sensors:
POSITION on the main ribbon (0V to 8V)
PRESSURE on the main ribbon (0V to 8V)
PITCH BEND from two pressure points opposite the main ribbon, UP (0V to 2V) and DOWN (0V to -2V)
Simultaneously, UP CV (0V to 6V)
And DOWN CV (0V to 6V)
AXE has attenuators to set the maximum value of POSITION, PRESSURE and PITCH BEND UP and DOWN.
AXE returns its analog signals to RAZOR, a 6 hp Eurorack module via an RJ45 (Ethernet) cable.
In addition to outputting the five CVs created above, RAZOR:
creates 5V GATE (w/LED signal) and TRIGGER signals using a comparator between PRESSURE and an attenuated THRESHOLD.
can sample and HOLD the POSITION CV.
accepts any CV IN to add to PITCH BEND; the input is normalled to POSITION.
can attenuate pressure point UP and DOWN CV outs.
Additional Features:
AXE can be played in “Keyboard Mode” flat on a surface, or in “Guitar Mode,” held in both hands. It has RJ45 jacks on both sides of its enclosure to accommodate left- and right-handed grips. It also has a recessed switch to quickly reverse the orientation of the POSITION CV: either low to high moving outward from the enclosure (keyboard) or high to low (guitar).
