### 5/5 — Loving it! But please add a Balance control to final output!

*2026-03-24*

Excellent app. My only issue is that I output this to a rotary speaker. So I only need one output channel. If this app allowed me to send its output to the Left channel while sending nothing to the Right channel, I could then utilize the Right channel for a different app that does not go into the rotary.

### 1/5 — Confusing

*2025-03-23*

I paid a dollar just to see if I’d bought the update! I own the older version. Then I realized that the price of this version is $99! Since it’s my bad for not noticing the price increase, I’ll accept the charge. But $99 for an iPad organ?

### 3/5 — Invert drawbars?

*2024-09-23*

I can’t find a way to do this, which means the drawbars on my controller are working the opposite way organ drawbars do. This is a common feature in every organ app I’ve ever had, and it is a major oversight in an organ app that costs as much as this. If I’m just missing it somewhere, please let me know.

### 5/5 — This is good for my playing

*2024-04-06*

I like this app I was looking for a realistic Hammond organ app for no cost and I found VB3-II  the features are realy great if your looking for an Hammond organ app this will be the one your looking for
