Dual DTMF encoding

How retro! This morning i have been working on a dual channel DTMF encoder using Max/MSP. The main gist of things is to use 2 channels of DTMF to encode 8 bit data which can later be decoded in parallel by dedicated hardware. More about this when i put something together. Above you can see the main patch. Below you can see the subpatches. Yeah.

The 8 and 4 bit binary conversion is there only as a demonstration - it is not required for operation. The /16 and %16 objects are, so that the left and right four bit words can be extracted and sent to the individual DTMF encoders.
