I'm right now controlling an analog synth via Pd :-). I'm just using an arduino - works well. It depends how many CV sources you wanna have, though. Generating trigger signals (e.g. for envelope generators) is really easy because you can directly use the digital outs. CV for modulation is a bit more tricky because you have to smooth the PWM outputs of the arduino with low pass filters. I found that using two RC circuits in series (with C = 1 microFarad and R = 3,3 kOhm) works decently for pins 5 and 6 on the Arduino Uno (pins 9, 10, 11 have a lower PWM frequency and therefore might need a lower cutoff frequency). I'm thinking about trying out some multichannel DACs with 10 or 12 bit because PWM on the arduino is only 8 bit. DACs also operate at a much higher frequency so smoothing would be much easier.

I just emailed Andrew directly. Thanks!
