Help For an Attack Decay pedal

[Ludodiyer]

Hello folks!
i'm really fascinated from ADSR devices.i built a boss Slow Gear but is not so useful.i looked for a more decent pedal and i found it in this site:

DSR%20Generator.pdf

this schematic is a little too cryptic for my poor experience.here is what i don't uderstand:

1.i'd like some informations about the wiring of the pots.it seems too iterpretable to me..
2.what does mean "REF"?? (near D3) is it a mistake?
3.i'not sure of the meaning of the nomenclature v++.eventually i will join it to +15v.is it correct?
4.there is a part of the circuit after IC6B that is suspended.is this the output?
5.i don't know if the circuit is positive or negative ground.

i admit i'am a little bit ignorant.but it seems to me a quite-easy built if you give to me the knowledge i need.thanx in advance.Ludo

That would appear to be the schematic for an synth-type envelope generator. It would need to be used with a VCA and trigger/gate generator to do what you want. Best to back away from this one.
