http://blamsoft.com/rack-extensions/polymodular-system/Blamsoft, with cooperation from other developers, has developed a new communication protocol for Reason. PolyCV allows polyphonic instruments to be triggered by CV. Multiple channels are supported, like in the MIDI protocol. PolyCV takes advantage of the fact that monophonic gate and note signals are greater than or equal to zero and uses strictly negative signals. PolyCV uses the concept of events, which include channel, note, and gate. It can be added to monophonic gate and note jacks and still allow legacy monophonic behavior. A one way handshake from sender to receiver signals that PolyCV is present. This prevents bad negative inputs from triggering events. The handshake happens periodically during the idle time to allow for multi-hop connections.
Key Features:
• PolyCV uses the channel concept from MIDI. Multiple channels allow for special use cases, like the Polymodular System.
• PolyCV uses the same gate and note jacks as monophonic inputs and outputs so it can be added to existing instruments and doesn’t require an extra set of jacks for newly developed instruments.
• When a PolyCV sender is plugged into a monophonic receiver the input will be completely ignored because PolyCV is strictly negative.
• A PolyCV receiver can be added to existing instruments in existing songs. Because it has a handshake, the inputs will not receive spurious notes even if an existing song has a strange input.
• A PolyCV sender can be added to existing instruments in existing songs. A switch can be added on the back of the device that defaults to monophonic mode, but when switched to polyphonic mode can enable PolyCV.
• PolyCV is within the range of standard CV -1.0 to 1.0 so it will not cause strange extreme inputs and can pass through all splitters. More specifically, it is limited to -1.0 to just below 0.
Fun times in Reason.
