1. Q: Can I connect the Synido Scale Pocket to a speaker or audio interface?

A: The Scale Pocket has a built-in speaker, so it can produce sound on its own. If you want to connect it to a speaker or audio interface, simply use a 3.5mm audio cable from the headphone output to send audio to your external device.

2. Q: How do I change the keyboard sound/voice on the Scale Pocket?

A: Slide the first fader on the Scale Pocket to select from 12 different keyboard voices. The position of the fader determines which voice the built-in speaker will play.

3. Q: Why do my notes vary in volume when I play?

A: The keys are velocity-sensitive — the harder you strike/press a key, the louder the sound from the device or DAW. If you want consistent volume regardless of playing力度, press the "Fixed Velocity" button to enable it. The volume will then be uniform.

4. Q: The key noise seems a bit loud. Is this a defect?

A: This is normal and is due to the key-triggering mechanism. It does not affect performance or functionality in any way.

5. Q: When I open a DAW on my mobile device or computer, both the Scale Pocket and the DAW produce sound. How do I mute the unit's built-in speaker?

A: Simply press the Vol- button on the Scale Pocket until the volume is turned all the way down. The volume buttons do not affect the DAW's output level.

6. Q: My Scale Pocket doesn't respond when connected to certain phones/tablets.

A: First, check if your phone has an OTG setting and enable it. Then remove your phone case and reconnect the USB-C cable at the phone/tablet end. If the issue persists, it may be a compatibility issue — try connecting to another phone if available.

7. Q: How do I connect it to an iPhone/iPad with a Lightning port?

A: Due to Apple's regulations, we are unable to provide unauthorized Lightning accessories. You'll need to purchase a Lightning OTG adapter separately. The Scale Pocket comes with a USB-C to USB-C cable, so you'll just need a USB-C to Lightning OTG adapter. For Apple's official "Lightning to USB 3.0 Camera Adapter" (USB-A to Lightning), you'll also need a USB-A to USB-C cable.

8. Q: The Scale Pocket won't power on when connected to my iPhone/iPad.

A: Due to Apple's power output limitations, the device may not get enough power from the iPhone/iPad. Please charge the Scale Pocket fully before connecting it to an iPhone/iPad.

9. Q: I'm hearing noise/glitches when playing software instruments on my phone/tablet.

A: This is usually caused by a poor connection at the phone/tablet end. Try unplugging and reconnecting the USB cable at that end until the noise disappears.

10. Q: How do I check the battery level, and how long does charging and playback take?

A: The Scale Pocket does not have a real-time battery indicator. Charging takes about 3 hours, and battery life is roughly 6 hours depending on usage.

11. Q: What do the 12 options (C to B) on the second fader represent?

A: These represent the ROOT note. The root is the fundamental note of a scale or chord — the first note in a scale. After selecting a scale type, adjusting the root note will change the key backlight (the root note lights up green).

For example, the C# Major scale consists of: C#, D#, F, F#, G#, A#, C. C# is the root, and its key will be highlighted in green.

12. Q: What do the options on the third fader represent?

A: These represent the scale type. A scale is an ordered sequence of notes arranged in a specific pattern. The Scale Pocket offers 11 scale modes. When a scale mode is selected, the key backlighting will change accordingly to indicate the active notes within that scale.

13. Q: What do the different key backlight colors mean?

A: When a scale mode is enabled, the key backlight indicates the active notes within that scale.

For example, the C# Major scale contains: C#, D#, F, F#, G#, A#, C. The main octave active keys are lit in red, the root note is lit in green, and active keys in other octaves are lit in blue.

14. Q: How do I identify which notes are in the selected scale?

A: Once a scale mode is enabled, the active notes in the main octave are shown with a red backlight, the root note is green, and active notes in other octaves are blue.

For example, in the C# Major scale (C#, D#, F, F#, G#, A#, C), the main octave will show (green + red lit keys):Pic 1 ; Active notes in other octaves (blue lit keys): Pic 2

15. Q: How do I play numbered notation songs using a fixed scale?

A: Once a scale is enabled, the active notes in the main octave are lit red, the root is green, and active notes in other octaves are blue.

For example, in the C# Major scale: C#, D#, F, F#, G#, A#, C — the number notation would be: C# = 1, D# = 2, F = 3, F# = 4, G# = 5, A# = 6, C = 7. Dotted numbers in the notation refer to notes in the higher octave.

16. Q: Why doesn't the SUSTAIN button create a sustain effect?

A: Hold down the SUSTAIN button while playing. Notes will continue to ring after you release the keys and fade out naturally. When you release the SUSTAIN button, notes will stop immediately upon key release.

17. Q: Can I connect traditional MIDI devices to the Scale Pocket to use it as a sound module?

A: Yes. The Scale Pocket supports standard MIDI protocol. Use the included 5-pin to 3.5mm MIDI cable to connect another MIDI device's MIDI Out to the Scale Pocket's MIDI In. Audio will then be output from the Scale Pocket.

10. Q: How do I connect the Scale Pocket to a DAW on my computer (using Ableton Live as an example)?

A: Follow these steps:

19. Q: How do I connect the Scale Pocket to a mobile DAW (using GarageBand as an example)?

A: Connect the Scale Pocket to your phone's USB-C port using the included cable. Open GarageBand — it will automatically detect the device. You can now play and send MIDI data to the app.

20. Q: Can I change the MIDI output channel when using the Scale Pocket with a DAW or synthesizer?

A: Yes. The first fader (voice selector) also functions as a MIDI channel selector, with 12 channels available — from left to right: Channel 1 to Channel 12. When using it as a MIDI controller, we recommend muting the built-in speaker to avoid interference with your software instruments or synthesizer.
