Default Vector and Expander Calibration files

Hey the manual says files VSCAL.DAT and EXCAL.DAT are available on the website but I can not find them anywhere. I deleted the F12_VS folder while trouble shooting sync issues and do not see those files when mounting as USB

Pitch between octaves is wildly different at about 23c per octave when using the Vector (performed isolation tests with other gear etc).

Help!

From the manual:

The Vector sequencer comes with one or two data files that store
calibration data for the Pitch CVs. The VSCAL.DAT is for the Vector,
EXCAL.DAT is for the expander. If you purchased your Vector and
Expander together, the two files may be pre-loaded. If you purchased an
Expander separately, you can download the file from
http://vector.five12.com.

Hi Steve,

Check your email for the calibration files. I keep copies of them for every unit. The should go inside the F12_VS folder.

Cheers,
Jim

Okay so did that with the calibration is still 23c out over an octave

what do I try next?

I tested for both the main and expanding units

This all worked out. There is a process to manually update CAL files but from what I understand the next FW release, or one very soon, should make the manual process redundant. The following is my rewording of what Jim told me to do.

*OBJECTIVE*

Manually restore Expander and Vector DAC files to your Five12 hardware. You must use the files matched by Jim to your hardware serial number.

*PREPARATION*

EXCAL.DAT (must provide serial number of your EXPANDER to Jim at Five12. Calibration files are unique)
VSCAL.DAT (must provide serial number of your VECTOR to Jim at Five12. Calibration files are unique)

USB connection to your VECTOR - mount the storage as an external disk an place the files in the F12_VS folder along with the PREFS and PROJECTS folders)

*PROCESS*

Navigate to the ROUTE page in GLOBAL view
- Press Global
- Press NEXT twice to go to the ROUTE page

Hold SHIFT and press NEXT to go to the TUNE page

Turn ENCODER 9 clockwise until the DAC CALIB screen is visible
- Select DAC PIT 1 (already visible)
- There are DAC PIT fields numbered 1 to 6
- There are V-Out fields (Encoder 2), ranging from -3 to 7.
- For *EACH* DAC Pitch field (on Encoder 1):
- For *EACH* Voltage (-3 to 7):
- Turn ENCODER 4 up and down *once*
- This will increment and decrement the setting by one
- MSB bumber will change (for me it was 264 - 265 - 264)

... This is necessary for all voltages, noted on screen as V-OUT (-3 to +7), per DAC PIT number (1 to 6)
... Be sure that you repeat the same process but increment DAC PIT from 1 to 6
... Take care when using encoder 4 that you increment, decrement values correctly or you will force things out of tune

Use SHIFT and PART to save the current project, press NEXT to save

This will save your pitch calibrations to the PREFS folder in F12_VS of your Vector

Exit from the TUNE screen by selecting another view, ie GATE or PITCH etc

Steve: Thanks for writing this up so neatly. However, I missed a bit when giving you the original instructions: you need to update the value for *all* voltages across *all* DACs. When updating the code for the next FW build, I realized that this trick only works for the current (ahem) voltage, not for all of them, so the process takes a bit longer, but actually not all that long. I have gone ahead and updated your detailed description to include the extra steps, I hope that was OK!

This will be un-necessary in the next FW release -- the update will be automatic.

Also, Steve, this explains that one octave you had that was way off w/ the tuner -- it was a voltage that we didn't update.

Cheers,
Jim

THAT MAKES SO MUCH MORE SENSE !!!

HAHAHAH THANKS JIM and happy to be a part of working through all this.

I will cease the process I am working on via email and wait. It is close enough and yes definitely explains the anomalous pitch issue.

Thanks,

Steve.

Done. Made 2 small corrections to process but yes, it definitely works and on my test ouputs of set 1 and 3 my pitch is now as close to perfect as I would expect with CC variants being within 3 or 4c per octave as opposed to 10 or 12 per octave.

Note to anyone reading this - be sure you have your .DAT files for the Vector or the Expansion board. Jim can supply those if you do not!
