## What is Program Changer?

Program Changer is a super simple tool to send and receive MIDI Program Changes.

The big keypad allows for quick entry to switch your synthesizer patches, audio mixer presets, lighting desk scenes, or whatever you can link to a MIDI Program Change command. Use the plus and minus keys to quickly jump up and down.

Alternatively, Program Changer can just give you a big display of incoming Program Change numbers in 'receive' mode.

Program Changer sends and listens to all MIDI devices or network sessions available. I'm seriously considering Audiobus support for inter-app MIDI commands. Let me know if you need this, then I might hurry up.

If you have any questions or feedback, don't hesitate to contact me directly via contact@oscarbouwmans.nl.

### 5/5 — One small suggestion…

*2022-05-09*

This is (almost) exactly what I have been looking for to change patches on my guitar synth.  Not being a programmer, I have no way of knowing how much effort would be required, but it would be great to be able to scroll by holding the up/down increment buttons down.

### 4/5 — Nice!

*2021-05-31*

Good for what it does. Would like bank changes as well.

### 3/5 — peccato...

*2020-06-01, version 1.0*

l’idea è semplice e geniale, é quello che ci vuole per scorrere i preset del tuo strumento dove spesso si selezionano con difficolta, o si vedono male.invece dei bei tasti grandi illuminati e touch,con il tastierino numerico per saltare da uno all’altro é l’ideale. per cambi in sicurezza, solo che l’unico preset che mi seleziona è il numero 1...nient’altro...do 3 stelle sulla fiducia, e sull’idea ma l’app non mi lavora come vorrei.peccato...

### 1/5 — It doesn't work correctly

*2020-04-30, version 1.0*

After sending any program change number, it sends immediately another program change to program number one.

### 5/5 — Yaaaaaaaassssssssssss!

*2020-02-29*

Exactly this!

### 5/5 — Simple and free

*2019-01-06*

It works.
