StroboPLUS HDC
GREAT PRODUCT - MORE THAN JUST A TUNER Instruction Manual Pages
Overview
Since 1948, Peterson Strobe Tuners have defined the standard in tuning accuracy. The StroboPLUS HDC encompasses decades of tuning authority and technology to deliver the ultimate strobe tuner/metronome combo!
The StroboPLUS HDC’s 0.1 cent tuning accuracy will tune any instrument with the utmost precision. Featuring a high-definition, multi-color display with variable color LED backlight, the StroboPLUS HDC display can be seen easily across the stage, bench, studio or classroom. Over 200 exclusive Sweetened Tunings® and Guided Tunings on-board accommodate a variety of instruments, temperaments, and musical genres.
The highly configurable metronome features precise 0.1 BPM adjustability in eighth notes, quarter notes, dotted quarter notes or half notes, a tempo range of 10-280 BPM, over 100 subdivisions, accent patterns, and polyrhythms. The StroboPLUS HDC can also be used to play thousands of bars of tempo maps, programmable from the Peterson Connect Web App. A single tempo map can play an entire score of meter changes, accent patterns, subdivisions, bar colors, silent bars and gradually curved tempo changes like accelerandos and ritardandos. The StroboPLUS HDC is the perfect tuning, ear training and rhythm tool all in one package!

A couple of tips for future updates / improved models:
1. An LCD with full description of each tuning mode (I forget some of their acronyms and the descriptions for all of them)
2. The ability to update a full piano temperament across all 88 keys to match your ensembles piano (I could take measurements with this tuner straight after a fresh piano tuning and use it to help the rest of the band lock into our keyboards adjustments, this would great in a studio too!)

I do not want to set it for each tone. I want to read it in the dsplay.
Weirdly the $9.99 iOS app is able to display the cent value.
The hardware version for $129 isn't.
So I am using the phone app instead.
PLEASE fix it!

Only charged it once and has had a few hours use so far. Still showing 3 bars on the batter indicator.
Nice to have the metronome built in as well.

Frequently Asked Questions
Does my StroboPLUS HDC require calibration?
Unlike more modern Peterson strobes, legacy models such as the Peterson 400, 420, 450 and 700 do require occasional calibration.
If you require service, please open a support ticket and return the tuner for repair.

How do I read a strobe display?
Adjust your instrument until the pattern is as close to still as possible. Strobe displays are 'real-time' and extremely precise. They require very fine tuning adjustments to stop the display because the frequency/pitch of any instrument is never totally stable.
You'll quickly learn to read the display, make the most precise adjustments and appreciate the high resolution that only a Peterson provides.

Peterson Connect does not detect my StroboPLUS HDC in Linux environment.
Chrome needs access to /dev/hidraw*, so either set "chmod a+rw /dev/hidraw*" or start chrome as root with the --no-sandbox option
*Some Ubuntu based distros do not allow running Chrome as root with the --no-sandbox option enabled. -Running as root without --no-sandbox is not supported. See https://crbug.com/638180. You can however run Chromium as a normal user and invoke that option.
Some users have reprted a fix by adding a new udev rule as follows: KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev", ATTRS{idVendor}=="2368", ATTRS{idProduct}=="*SEE BELOW"
* Some Peterson products operate in two different modes with individual product id's for firmware update operations. Multiple rules may need to be created. Here is the list of Peterson USB product ID's
idProduct =
Stomp Classic = 8002
StroboPLUS HD = 0003
StroboPLUS HD Firmware Mode = 8003
StroboClip HD = 8004
StroboStomp HD = 8005
StroboPLUS HDC = 0006
StroboPLUS HDC Firmware Mode = 8006
If there is trouble connecting or reconnecting as a product is switching modes, ex: StroboPLUS HDC product id 0006 to StroboPLUS HDC Firmware Mode 8006 run the command:
"sudo chmod a+rw /dev/hidraw*"
This command will solve any "waiting on user input" or if the update button in Peterson Connect is unresponsive. The command may need to be executed more than once.
