Axe & Razor

External Ribbon Controller with Pitch Bend and Rack Interface

AXE & RAZOR work together as an external analog ribbon controller for your Eurorack modular synthesizer.

AXE ribbon controller 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.

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).
