"One JKJ CV-5 midi to CV converter, built by Kyle Jarger with documentation.
The CV-5 is a pretty amazing box relative to off the shelf units these days. Note the front panel says CV-4 but it is a CV-5 internally. Kyle built this for me and was out of CV-5 panels

It is switchable between volts/octaveHz/volt. It can be calibrated to any voltage steps you want (within reason)

It offers 1 MIDI IN and MIDI THRU with several modes for the 6 output jacks.
It has:
CV/OUT
GATE AND 2/TRIG OUT ON A TRS JACK

It offers:
10 ways to control the LFO
13 ways to control the LFO wave form (it's not syncable totally, but you can restart the lfo shape based on tempo
9 choices for LFO sync to clock
can send pitch to filter jack
3 choices on portamento
4 pitch bend depth choices
4 ways to route velicity
8 ways to route velocity
7 destinations for CC1
5 choices for CC4 destinations
3 ways for note priority
7 MIDI Note ranges (5 octaves)
2 ways to rout out of range notes
2 ways to control gatesw/triggers
7 system controls, to lock, save, resett, return to default, disaable/enable changes
4 operating modes
7 seq clock modes
enable or disable 2nd MIDI channel
10 hardwired CC assignments

It has DIN Sync out

EVEN MORE FUN IS MONO AUDIO IN to STEREO out and the ability to control pan position using MIDI CC controller.

Runs on any 9-12VDC 100ma pos-tip wall wart You supply that

The only quirk is that CC values are 0-126 not 1-127 which means that for most MIDI controllers you have to round down by one number to send it what you expect."

JKJ CV-5 midi to CV converter

via this auction
"This is a great midi to control voltage converter that allows analog synthesizers and other modular devices to be controlled by a midi keyboard, rhythm machine, or sequencer. The CV-5 works with any monphonic analog synthesizers which conform to the 1 Volt per octave or Hertz per Volt scale standards. The unit can be confiigured by sending midi program changes. The CV-6 goes well beyond most simple midi-to-CV converters and offers high quality portamento, fast note response times, filter and auxiliary outputs, dynamic audio processing (volume and pan control), syncable LFO, vibrato, sample and hold, pitch bend, and DIN sync output. With five CV outs, it can actually be used to control two synthesizers."
