I've decided to part with my Analogue Systems Midi to CV/gate/ctrl
converter. Info here:
http://www.analoguesystems.co.uk/modules/rs140.htm

This is *really* the best of show for this type of module in eurorack
format. It does the standard CV/Gate, it does Midi CC to voltage, it
does triggers, it does clocks (with programmable divisions), it
generates an internal LFO (that can sync to midi clock) and it can map
a Midi CC to control the level of that LFO for modwheel vibrato
purposes. I'm sure there's other neat features I'm not thinking of,
but the short of it is that it's awesome.

$300 + shipping (currently located in the US), which is significantly
cheaper than one can be had new
