Mapping Discussion

[rubberband]

Posting with a follow up - I solved one problem but still have an issue.

My issue with notes being recorded from the CV inputs being off was caused by another module (mute switches) in the pitch CV signal chain dropping the voltage.  So that's solved: the calibration on both the NerdSeq and the metropolix is excellent.  Now if I pass pitch and gates using the input assign in the setup menu, everything tracks perfectly.  

When I try to do this with mapping though:

CV  IN 3 ---- > CV  PTCH  CV 4
CV  IN 4 ---- > TRIG GATE TR 4

The pitch doesn't track properly and ends up out of tune.  I'm guessing it's because the CV is being read 1000x per second or whatever the interval is and continuously updated as opposed to just being redirected straight to the outputs?  The original sequence is still there, just out of tune and sounding kind of alias-y or chorus-y.

Am I doing something wrong or is this just a limitation for now?  I've solved the problem eternally with passive mechanical switches but it would be even better to have it all managed internally (and be addressable in patterns for performance).

Most probably you got the live inputs also routed to the outputs? These will concurrent with each other one locking to the note and one passing the pitch continously.  With passing there is always sampling involved. And if the pitch is slightly different than the actual note then one will compensate it and one not.
Try to use only on of these. In the upcoming version you can turn on/off the live input through the mappings so only on part is needed.

Thanks! I tried it again with the inputs not passing to anything and it was still out of tune (but no more chorus or weird sounds)

I’ll wait for the new version, it’ll be fine. For now I’m just using an XMAP command to set a precise voltage on a couple of CV16 ports to open a pair of dual VCAs to exactly the right level. Might need occasional recalibration but seems to be doing the job right now!

You got to lock it to notes and not send out pitches. 
Change the cv input to notes using the p2note calc command. Depending on your input you might also have to add some digits. But the destination uses then note values (change that, too) and it‘ll lock to notes.

Gave it a shot, still not quite right.  My external VCA solution is working for now (and I'm pretty sure it's me that's doing something wrong) so I'm not going to mess with it any more (or use more of your time!) until next week's performance is done.

For reference I tried:
CV  IN 3 ---- > SETV V  G SRC
CALC P2NT VG00 > CV NOTE CV4

It works, but is still slightly out of tune - ~262Hz for middle C if I pass everything through using the input assignment, and ~252Hz if I use the XMAP way.

Also, I've posted this before but want to post again:  The NerdSeq rocks, and the support for it is best in class.  Please keep doing what you're doing, it's awesome.

Noticed that when using a Mapping Value to set CV Glide or MOD Glide the value range is transformed to 0x00 - 0xFF instead of 0x000 - 0xFFF. So its not possible to make use of the full range from the mapping screen.

Oh yes I see. Will be fixed in the upcoming version. THX
