This simple key-scale remapper, with eight scales and transposition picks up [channel:pitch:gate] messages from any source, optionally transposes it, remaps the pitch to standard scales, and forwards the message to the Polyvoice multichannel controller on the same channel. Preset scales are major, minor, blues, and pentatonic.

It ispart of the ULA ring, a simple, open, and extensible way to connect many parts of a system together. All Ula subpatches can send messages to each other on single-wire ring, and they can be any sequence on the ring. The Ula controller can display all ring communication and stops stack overflow due to endlessly cycling messages. All messages passing through the Ula controller may optionally be printed to the to the Max debug window with a timestamp. Because the controller receives all ring messages, it can also manage message recording and playback, to recreate any AV composition on the Ula system.
