Frequently asked questions

Antivirus related issues can easily be solved.

Antivirus software is always suspicious of programs downloaded from the Internet. The programs on this website can be fully trusted though.

Modern antivirus software will automatically send a copy of the program to their lab for analysis. You will receive a message from them some time later, confirming that the program is indeed clean and safe to use. This will take between a few minutes to a few hours. In the meantime you will not be able to use the program.

As soon as you receive the confirmation from your antivirus software you can start the program with the icon on your desktop. Do not install the program again because your antivirus software might think it is a new program and start analyzing it all over again.

If you still have issues regarding your antivirus software, please send us a message with the following information:
1. The name of your antivirus software.
2. A description of the issue.
3. The name and version of your operating system.

If you deleted or uninstalled the program by accident, you can reinstall it on the same computer using the setup file you received from me.

An Internet connection is needed to download and install the software. Use one of the methods below to create a temporary Internet connection:

• Connect an ethernet cable from your computer to your Internet router.
• Enable the WiFi on your computer and connect to your WiFi network.
• If you do not have a WiFi network, visit a public Internet Cafe.
• Turn on the WiFi hotspot on your smartphone and connect to it with your computer.
• If your computer does not have WiFi, insert a WiFi USB adapter.
• Activate Bluetooth on your smartphone and set it to discoverable. Also turn on the hotspot feature on your smartphone and connect to it with the Bluetooth of your computer.
• If your computer does not have Bluetooth, insert a Bluetooth USB adapter.
• Connect your computer with another computer that does have an Internet connection using an ehternet cable. Share the Internet connection on the other computer in the Windows Network Connection Properties.

It is probably your antivirus software blocking the setup. Try to disable your antivirus software temporarily. This is often possible by right clicking the antivirus icon in the bottom right corner of your desktop (in the system tray).

What antivirus software do you use? We will contact them to report a false positive.

You suffer from a 50 or 60Hz power hum. This hum comes from the mains. Some microphones are extra sensitive to such a hum. Try the following possible solutions:

• Try a USB microphone. A USB microphone such as the 'Samson Go Mic' is recommended.
  
• When using a laptop, unplug the power cord and let the laptop work on the battery.
  
• Use a grounded plug.
  
• In the “Sound Input Settings” screen enable one of the Hum filters.
  

An external microphone with a cable connected to the computer is the preferred configuration, because it can be easily placed in a proper location. That means that a simple microphone connected to your computer's soundcard will suffice. The frequency range of such a really cheap microphone is in most cases not known. A high quality dynamic microphone will give better results, especially in the lower frequencies. Generally spoken a USB microphone will do too. In that case, the internal sound card of the computer is not used, which can be an advantage. The much more expensive condenser microphones are usable, but they won't give you a better tuning-result. At all times, digital effects in the microphone software have to be disabled!

Updates are available for the OS versions listed below.

This can be the result of one of the following:

• The number of reeds does not correspond to the number of reeds set in the tuner's configuration. This can be corrected by clicking the 'Reeds' button.
• The tuner is capable of tuning three reeds at the same time.
  
  
  • When measuring single notes, the three reeds have to lie within that same note. The three reeds must not lie within multiple octaves.
  • When measuring chords, each note of the chord must contain one reed and all reeds must lie within the same octave.
  • When measuring octaves, each reed has to lie within different octaves.
• When the microphone is positioned on one side of the accordion, it is possible that the recording level of reeds on the other side of the accordion is too low. In that case, you will have to reposition the microphone.
• When two reeds sound at exactly the same frequency (within 0,6 Herz difference), the tuner will recognize these two reeds as one.

The beat lists are not included with the software. The trial version of the software includes a few examples. However, these are only examples. You can easily create the beat lists yourself. With the module "Record & Report" you can even easily copy them from an existing instrument.

See chapter "Beat lists" of the manual for more information

The accordion tuner can measure up to 3 reeds simultaneously. By creating two beat lists it is possible to tune an accordion with 4 (LMMH) or 5 (LMMMH) reeds.

• Create a beat list for 3 reeds (LMH). The remaining M-reeds will be tuned using a second beat list.
• Create a second beat list for 2 (MM) or 3 (MMM) reeds. One of these reeds will be tuned with the first beat list. This reed is in this beat list too, so it can act as a reference while tuning the remaining M-reeds.
• Tune the first 3 reeds (LMH) with the first beat list. Keep the remaining (1 or 2) M-reeds muted.
• Tune the remaining (1 or 2) M-reeds with the second beat list. Sound all M-reeds; also the one already tuned with the first beat list. Keep the L and H-reeds muted.

• While measuring a tone, the number of sounding reeds must be the same as the selected number in the tuner software. The other reeds must be muted.
• After starting the tuner software, do not start playing a tone as long as the text "Initializing..." is displayed.
• The sounding tone needs to be constant for three seconds or longer. The text "locked" will appear then.
• Before playing a sound a few seconds of silence is necessary.
• If the note to measure lasts for too long (approximately 30 seconds), then it will be recognized as a background sound and will be removed.
• See to quiet surroundings. A humming fan too close to the microphone can disturb the recording.
• You should not use a microphone specific for voice. Too many frequencies will be filtered out. A USB microphone such as the "Samson Go Mic" is recommended.
• Do you have a stereo microphone? It must be configured as mono!
• Make sure the microphone sound is not played through the speakers. Some soundcards support this through their Windows Mixer Settings.
• Any digital sound effects in the microphones driver software have to be disabled! Look for effects like “noise reduction” and “echo”.
• In your microphone's properties, advanced tab: disable any Signal Enhancements.
• On macOS, the Mic Mode has to be set to Standard: 1. Start the tuner. 2. Click on the yellow microphone at the top of the screen. 3. Set the Mic Mode in all tabs.
• On macOS, Ambient Noise Reduction has to be turned off: 1. Go to System Settings. 2. Select: Sound. 3. Select: Input. 4. Turn off: Ambient Noise Reduction
• The microphone must be placed at the side of the instrument where the sound is coming from.
• The microphone must be placed close to the instrument.
• Make sure the right microphone is selected in the tuner software's settings screen. With laptops it is easy to mistakenly select the internal microphone.
• Some computers suffer from a power supply hum. If you have a laptop you can check this by disconnecting the power cable. A USB microphone will solve this issue.
• A 50 or 60Hz power hum filter can be enabeld in the settings screen of the tuner software. In some situations this filter can prevent the software from detecting the lower tones properly.
• In the settings screen of the tuner software the microphone volume has to be configured as sensitive as possible. The signal strength should never reach the red zone though.
• If there is a "boost" checkmark for the microphone (in the settings screen of the tuner software), you should try it and check its results.
• With newer computers sometimes a boost setting (often a percentage) in the microphone driver software is supported.
• The minimum beat that can be measured is about 0.6Hz. Below that, the reeds have to be measured separately.
• Keep the bellow pressure constant while measuring. The pitch of a reed decreases when the bellow pressure increases.

The trial version is meant for getting a good idea of the possibilities of the tuner. Only part of the notes from the scale can be measured with this version. The following notes are supported:

E0 F0 G#0 A0 C1 C#1 E1 F1 G#1 A1 C2 C#2 E2 F2 G#2 A2 C3 C#3 E3 F3 G#3 A3 C4 C#4 E4 F4 G#4 A4 C5 C#5 E5 F5 G#5 A5 C6 C#6 E6 F6 G#6 A6 C7 C#7 E7 F7 G#7 A7 C8 C#8 E8 F8 G#8 A8 C9

The software works just like a technician that tunes by ear. The software "listens" to the beats in the intervals of the particular piano (so the consonance of the instrument is taken into account). It not only listens to the fundamental tones, but also to a lot of harmonics.

The software uses the following model:

1. A4 will be at the user specified frequency. (default = 440 Hz)
2. The interval A3-A4 will sound clean.
3. Tuning the temperament octave F3-F4:
   The octave F3-F4 will sound clean.
   Major thirds will beat faster going up the keyboard.
   Major sixths will beat faster going up the keyboard.
   Fifths will sound clean.
   Fourths will beat slowly.
   The three major thirds F3-A3, A3-C#4, C#4-F4 will beat close to 7, 9 and 11 beats per second.
4. Tuning the bass:
   Octaves will sound clean.
   Fifths will sound almost clean.
   Fourths will beat slowly.
   Minor thirds will beat faster going up the keyboard.
   Major thirds will beat faster going up the keyboard.
   Major thirds will beat slower than minor thirds. (not always possible)
   Minor thirds will beat equal to major sixths. (not always possible)
   Octave-minor sevenths will beat faster going up the keyboard.
   Octave-augmented fourths will beat faster going up the keyboard.
5. Tuning the treble:
   Octaves will sound fairly clean.
   Fifths will beat very slowly.
   Fourths will have a slow beat.
   Octave-fifths will sound fairly clean.
   Tenths will beat faster going up the keyboard.
   Tenths will beat a little faster than thirds.
   Seventeenths will beat faster going up the keyboard.
   Seventeenths will beat faster than tenths.
   Double octaves will sound fairly clean.

Yes, you can tune a piano to any frequency you like. The A4-frequency can be set in the stretch screen of the software. You can even set the A4-frequency to the current frequency of your piano prior to recording the strings. Then after recording and before calculating the optimal stretch, you set the A4-frequency to the frequency you like.

The trial version is meant for getting a good idea of the possibilities of the tuner. As with the full version, the trial version can record all notes. After that, the optimal stretch can be calculated. The trial version calculates the optimal frequencies of all As (A0 - A7) and all Es (E1 - E7). These tones can then be tuned. All the tones in between cannot be tuned.

This way it is possible to tune a series of intervals over the entire range of the piano:

• Octaves: A0-A1, A1-A2 etc. E1-E2, E2-E3 etc.
• Fifths: A0-E1, A1-E2 etc.
• Fourths: E1-A1, E2-A2 etc.

You can download the trial version here

Check out the explanation here.

• All keys of the piano need to be recorded before calculating the optimal stretch.
• While measuring a key, only one string may sound. The other strings (of the same key) must be muted.
• For each key only one string needs to be recorded. If a string is difficult to record, you can record one of the other strings of this key.
• The keys need to be recorded from low to high. You cannot skip a key. This means that when one key cannot be recorded, all higher keys cannot be recorded either.
• See to quiet surroundings. A humming fan too close to the microphone can disturb the recording.
• You should not use a microphone specific for voice. Too many frequencies will be filtered out. A USB microphone such as the "Samson Go Mic" is recommended.
• Do you have a stereo microphone? It must be configured as mono!
• Always use a recording of the same piano. After structural changes (like replacing strings), create a new recording.
• Make sure the microphone sound is not played through the speakers. Some soundcards support this through their Windows Mixer Settings.
• Any digital sound effects in the microphones driver software have to be disabled! Look for effects like “noise reduction” and “echo”.
• In your microphone's properties, advanced tab: disable any Signal Enhancements.
• On macOS, the Mic Mode has to be set to Standard: 1. Start the tuner. 2. Click on the yellow microphone at the top of the screen. 3. Set the Mic Mode in all tabs.
• On macOS, Ambient Noise Reduction has to be turned off: 1. Go to System Settings. 2. Select: Sound. 3. Select: Input. 4. Turn off: Ambient Noise Reduction
• Make sure the right microphone is selected in the tuner software's settings screen. With laptops it is easy to mistakenly select the internal microphone.
• Some computers suffer from a power supply hum. If you have a laptop you can check this by disconnecting the power cable. A USB microphone will solve this issue.
• In the settings screen of the tuner software the microphone volume has to be configured as sensitive as possible. The signal strength should never reach the red zone though.
• If there is a "boost" checkmark for the microphone (in the settings screen of the tuner software), you should try it and check its results.
• With newer computers sometimes a boost setting (often a percentage) in the microphone driver software is supported.
• The tones in the highest octave sometimes sound too short. You can strike these strings (only the highest octave) repeatedly.
• If the complete piano’s pitch is too low or too high, the A4 frequency in the stretch screen can be changed accordingly. After recording all tones, change the A4 frequency back to the desired pitch; often 440 Hz. After that, calculate the optimal stretch.
• If some tones are too low or too high, pre-tune these tones (with the tuning hammer) so the tuner software will detect the right tone.

• While measuring a tone, the number of sounding reeds must be the same as the selected number in the tuner software.
• Before playing a sound a few seconds of silence is necessary.
• See to quiet surroundings. A humming fan too close to the microphone can disturb the recording.
• You should not use a microphone specific for voice. Too many frequencies will be filtered out. A USB microphone such as the "Samson Go Mic" is recommended.
