CONTROLLER * It is now possible to place additional modules next to Controller module on its row. All modules placed on that row will be present on screen in Controller mode. * Improved color selection for Controller label background/foreground colors. * Rack position and zoom is now correctly saved and restored when entering and exiting Controller mode. APP FEATURES * Imroved handling of external assets, e.g. samples loaded to sampler modules. We fixed a couple of bugs in this area and made it easier to share patches that use external assets. Please read the updated External Assets section in the app manual for details.

Response from developer

Добрый день, можете, пожалуйста, написать на support@mifki.com в чем проблема с автосохранением и/или как бы вы хотели, чтобы это работало? Спасибо.

The Controller Panel!!

A MiRack lover for 3+ years, being on a break from due to no MiRack update, logging in 3 days ago, seeing the V4.50 update (!!!) I was happy!

But then, the Controller Panel? In ~2 1/2 days, I’ve used it as the beginning panel for a new:

- double 4 Step binary pitch sequencer!
- individual clock for each of the 8 steps! FWD/REV control for each
- 2 to 8 steps for each Step’s pitch
- 4 binary pitch buttons = 16 diff. Pitches for each step.
- quad quantizer

More coming 8n the future, depending on Panel upgrades.
Will be freely available. (Is now, early as is, at Reddit.)

WtG MiRack ciders!!!,

The promise Updates

I remember, the promise, of many updates soon. But nothing at all...

Insane!

This app along Koala Sampler are the 2 best music apps on the App Store

AUv3 is great - VST and ASIO?

Now that VST and ASIO are open source, it would be an amazing new addition. AUv3 support with the in-app purchase has unlocked such great utility.
