1.5. Overview
1.5.1. Making the connections
There are quite a few ways to connect KeyStep 37 with other types of equipment, from
vintage to modern. Below are some examples of potential setups:
1.5.1.1. .....with a Computer
KeyStep 37 is a USB class-compliant controller, so at its most basic level it can be connected
to any computer with a USB port and used as an input device for various applications.
The included MIDI Control Center software lets you choose which MIDI messages will be
sent by the mod strip and pedal, and also enables you to specify the global KeyStep 37
parameters.
However, KeyStep 37 can also be used without a computer attached! In this case, simply use
a 12V DC 1.5A center positive power supply (not included) or a standard USB mobile phone
charger to power the unit. Then connect everything else as shown in the following diagrams.
1.5.1.2. .....with external devices
As you can see, KeyStep 37 can be at the center of some amazing systems.
CV/Mod/Gate
KeyStep 37 will send control voltages to non-MIDI devices through its Pitch, Mod and Gate
connectors. It also can send data to those devices from the USB port of your computer or
from an external MIDI device.
