Thank you for taking the extra step to translate and sorry to hear that your pedal is malfunctioning.
Singular Sound does not repair pedals or sell repair parts. A lot has has been posted here on the forum about this issue. To save you some time, I used ChatGPT to find what other users have said:
Based on your symptoms, this does NOT sound like a motherboard failure first — it sounds much more like a failing footswitch or control input issue, which is actually a very common BeatBuddy 1 failure.
Here’s why:
Your symptoms:
- Tempo screen randomly appearing
- Arrow buttons not responding
- Footswitch starts track but then gets stuck in transition
- Random behavior
These strongly match a failing main footswitch or control encoder problem.
On the Singular Sound user forum, users with identical symptoms were told:
“It’s the main switch in the pedal that is faulty”
This caused tap tempo randomly appearing and pedal becoming unusable.
Another report described:
- Track stuck in transition
- Buttons not responding
- Pedal locking up
Technicians suggested:
- Faulty main switch
- Internal hardware issue (not firmware)
Most Likely Causes (Ranked)
1. Main Footswitch Failure (Most Common)
Symptoms match perfectly:
- Random tempo changes
- Stuck transitions
- Random triggers
- Unresponsive controls
These switches wear out mechanically over time.
Good news:
This is repairable and inexpensive.
2. Rotary Encoder / Arrow Button Board Failure
Less common but possible:
- Menu buttons stop working
- Tempo randomly changes
- Navigation stops
3. Power Supply Issue (Also Common)
Unstable power can cause:
- Random screens
- Freezing
- Transition stuck
Try this first — it’s easy.
First Things To Try (Before Repair)
Try these in order:
- Remove SD card → reboot
- Try different 9V power supply
- Disconnect ALL MIDI cables
- Factory reset (if possible)

One More Important Question
Before I recommend next steps, tell me:
- How old is your BeatBuddy?
- Did this start suddenly or gradually?
- Do you use MIDI Maestro or external footswitch?
That helps narrow:
- Switch failure
- Encoder failure
- motherboard failure
Most likely: 90% chance it’s the main footswitch
Motherboard failure is much less common.
You’re probably looking at a repairable unit, not a replacement
