[sdiy] Serial PC -> Analog CV

[Linium]

Hello,

There is a musical software like Csound, called PureData that allows (with 
an external lib) to send datas thru the serial port of a PC.

I would like to know what people here think about making a device that would 
get the bytes from the serial port and convert them to analog CV's. 

I have this idea since i am starting to have a lot of analog modules and i am 
not satisfyed with the traditionnal midi to cv convertors, which are 
expensive, with few outs, and often with 8 bits DAC. Midi is limited too.

I use PureData since some times now as a modular software synthesizer. It is 
free and run on windows and linux. It's a language in fact.
Imagine for instance using Hubi's loopback midi driver to connect 
Cubase/Logic to PD. In PD, midi note and CC would be then sent to the serial 
port and to the device. It has lot of outs and you can drive all your analog 
gears cheaply and efficiently.

Moreover, it is possible in PureData to generate software LFO and ENV,etc, 
specially if the serial port can be open at good speed. 
It is the important point. Serial port can be opened at least until 115000bps 
and PD should send bytes very steadily thru it. (i hope)
 
Do you think it make sense, is feasable ? 
The cost should be very reasonnable even with 16 CV outs, right ?

BTW, If you know existing projects very similar or IC that could suit well 
the project, i would be very happy to hear you, as well as comments and 
questions. 

Best regards,

Linium
