[sdiy] MIDI2CV & Arpeggio question..

[Jean-Pierre Desrochers]

Opinions asked for 2 things..

First--
I'm sure this question has been asked earlier somewhere..
 I'm about to build a MIDI2CV module and I'm at the very start.
 I'm wondering what will be the actual MIDI note that will
 produce 0vdc at the pitch CV output ? (CV out is 1V/oct)
 What I need to know is: 
 Is-it C3, C2.. C0, A0, A1 ?
 And what is the "standard" frequency for that 0vdc note ? 

Second--
This MIDI2CV will have an ARPEGGIO option
that when selected will 'scan' the present pressed MIDI notes.
I have 2 options in my ARPEGGIO programing:
-Scanning the notes starting at the oldest and ending with the newer note.
-Scanning the notes starting at the lowest MIDI note pressed
 and ending with the higher MIDI note pressed 
 (refreshing the in between modified notes).

What do you think.

Thanks for any help.
