ROUTING AUDIO AND CV66
Signal types
The following signal types are used in Reason Rack Plugin:
Audio signals
Audio means sound being sent from one device to another (or to/from your DAW host).
Audio connectors are shown as large quarter inch jacks and the cables are thick:
Audio connectors can be either inputs or outputs, as indicated on the panel.
You always route cables between inputs and outputs (it doesn't matter in which order you route).
The special case is the i/o device at the top of the rack, where the "Inputs" represent the inputs from the DAW
host and the "Outputs" represent the outputs to the DAW host. Thus, an instrument will have its own Output jacks
connected to the "Outputs" on the i/o device, to get the sound back into your DAW host.
Many devices have audio jacks in stereo pairs, with one labeled e.g. "Left/Mono" and the other "Right".
When you connect such a Left output, the Right is typically automatically connected too - but you disconnect it to
use a mono signal from the device.
CV/Gate signals
In the early days of synthesizers, before the MIDI protocol was invented, analog synthesizers could be interconnected
using Control Voltage (CV) cables. For example, one cable would be used for controlling pitch while another would
send a Gate voltage, basically telling a synth when to play a note and when to stop. A third cable might send a mod-
ulating signal to some parameter, e.g. varying the filter frequency. Today, this system has become quite common
again, thanks to the rise of modular synthesizers.
The CV signal cables in Reason Rack Plugin emulate this analog control system. CV cables send a value, which may
be static or changing. They do not carry audio, but are used for modulating parameters and controlling devices.
CV connectors are shown as smaller mini jacks, and the cables are thinner than the audio cables:
CV connectors can be either inputs or outputs, as indicated on the panel.
You always route cables between inputs and outputs (it doesn't matter in which order you route).
