Turbo Tuner Model ST-300 USB Operation

 

 

With the USB port you can easily modify the tuner's settings, Open Tuning offsets and Temperament offsets. The settings can be saved in an ASCII text file which allows you to easily upload different offsets and freely share them with others.

 

The tuner is accessed with ST300 Editor program. Before ST300 Editor can communicate, you must first install the driver and update the tuner's firmware if necessary.

 

The updater and ST300 Editor software works with Windows XP, Vista, 7, 8 and 10.

 

An Apple version is in the works and will be avaialble soon.

 

 

 
 

 

Device Driver Installation

 

Automatic Installation

 

For Windows Vista, 7, 8 and 10 the driver should automatically install when you connect the tuner to the computer with a USB cable and turn tuner on. It can take several minutes.

If you are running Windows XP, or if you have disabled automatic updates, do a manual installation.

 

Manual Installation

 

  1. For Windows XP, Vista or Windows 7, download Win7_Drivers.zip. For Windows 8 or 10, download Win8_Drivers.zip

  2. In the zip file there are two installation files:

    dpinst_x86.exe for 32 bit machines.

    dpinst_amd64.exe for 64 bit machines.

    Install the drivers before plugging in the tuner.

    If you are not sure which one you need, start with the one for 32 bits. If you have a 64 bit machine it will tell you.

  3. Install the driver first, then connect the tuner and turn it on.

Firmware Update

 

The latest revision is 2.11 If you bought your tuner after June 26, 2017 it already has revision 2.11.

File Format

The tuning file format has three sections, Settings, Open Tuning and Temperament. There is one Settings section. There are up to five Open Tuning sections (one for each mode) and up to five Temperament sections.

Settings Section

 

The settings section looks like this:

-----SETTINGS-----

A4Default: 440.0000
Transpose: 0

GUIT: OpenTuning
BASS: OpenTuning
CST1: OpenTuning
CST2: OpenTuning
CST3: OpenTuning

PASSTHROUGH_MODE: 0 // Optional
STAY_ON: 0          // Optional

--------end--------

The five modes are listed by name, and can be set to OpenTuning or Temperament.

The PASSTHROUGH_MODE setting only applies to the ST-300 full size when it is set to passthrough mode via the internal DIP switches.

If PASSTHROUGH_MODE is 0, the input signal is always passed through to the output. The footswitch turns the tuner on and off.

If PASSTHROUGH_MODE is 1, the tuner is always on. The footswitch mutes the output. Not recommended when powering the tuner from a battery.

STAY_ON If this is set to 1, the tuner will power up when external power is first applied, such as when powering up your pedal board.

 

Open Tuning Section

 

An typical open tuning section is shown below. It can have up to 9 strings. Each string will have a note, and octave, and a cents offset. The example below is for a standard guitar in equal temperament.

--------OpenTuning--------

Mode: GUIT    // One of the 5 modes, GUIT, BASS, CST1, CST2, CST3
Name: Guitar  // A name for the tuning, up to 8 characters
A4: default
Transpose: default

1: E4 +0.0
2: B3 +0.0
3: G3 +0.0
4: D3 +0.0
5: A2 +0.0
6: E2 +0.0

--------end--------

Each open tuning can have its own value for the A4 reference and transposition. If the A4: value is set to "default" as shown above, it will use the A4: value in the ---Settings--- section.

The Transpose: value can range from -9 to +9. It is the number of semitones the notes will be transposed. For example, to drop everything by one semitone, the value would be -1. Setting it to "default" it will use the value in the ---Settings--- section.

Temperament Section

 

A temperament section has the same fields for setting the mode, A4 and Transpose. You can have a cents offset for each of the 12 notes in the scale. A Temperament section for equal temperament is shown below.

--------Temperament--------

Mode: GUIT // One of the 5 modes, GUIT, BASS, CST1, CST2, CST3
Name: EQUAL
A4: default
Transpose: default

C:  +0.0
C#: +0.0
D:  +0.0
