Experience the authentic sound of a harmonium anywhere you go! With Jalra's MIDI Harmonium feature, you can connect a simple MIDI keyboard to your phone and carry a professional-quality harmonium in your pocket. Perfect for practice, performances, and music lessons on the go.
🛒What You Need
1. A MIDI Keyboard
You don't need an expensive keyboard! A simple, compact MIDI controller is all you need.
🎯Choosing the Right Size
Get a 32 or 37-key keyboard for the best harmonium experience:
- 25 keys: Too cramped - you'll run out of range quickly
- 32-37 keys: Perfect balance - comfortable playing range without being bulky
- 49+ keys: Too large and heavy for portability
Bonus tip: Look for keyboards with extra keys on the bottom side (like the Donner N-32) - these give you more low-range notes, which is ideal for harmonium playing!
Our top recommendations:
⭐Donner N-32 (Recommended)
Budget-friendly option with great build quality - perfect for beginners!
⭐M-Audio Keystation 32
Popular entry-level controller with 32 mini keys and a volume knob.
⭐Korg microKEY 37
Premium compact keyboard with natural touch.
2. Connection Cable
For Android: USB-C to USB-A cable or adapter (most keyboards come with USB cable)
For iOS: Lightning to USB Camera Adapter or USB-C to USB-A adapter (for newer iPads)
3. Optional but Recommended: Audio Setup
🔊For Better Sound Quality
Connect external speakers via AUX cable (3.5mm) for a richer, louder harmonium experience.
📱Phone Doesn't Have a 3.5mm Jack?
Solution: Get a USB hub with these features:
- ✓ Audio Out (3.5mm) - for speakers/headphones
- ✓ USB Port - to connect your MIDI keyboard
- ✓ PD (Power Delivery) - to keep your phone charged
Search for: "USB-C Hub with Audio Jack" or "Lightning Hub with Audio" (for iOS)

💡Pro Tip: Better Audio Experience
For the best sound quality:
