Should be a zero rating

App doesn’t function if it even starts. Crashes most times when I try to use it. Stay away and save your 3 dollars.

Needs updating

Just doesn’t work anymore, shouldn’t be on App Store if it’s not being updated anymore. Don’t waist your money.

Awesome for my setup

I have few mono synths and a puc+ (Bluetooth midi device)
And this sequencer is so much fun! I set the velocity to open the cutoff on my nyborg12 synth and it’s an instant Depeche Mode...
For $2.99 it’s great.

Complex, fun, frustrating

Grabbed this on sale 'cause it looked like fun, and it is fun. But it would be a whole lot better if there was some kind of tutorial. There is a manual available via the devs website. But a quick start option would be helpful. I have no idea what I'm doing. Also, why doesn't the app quit when told to? It has to be manually swiped from memory.

FAQ

What does midiSequencer do?

midiSequencer is a step sequencer designed to help you create unique sounds and rhythms from your iOS and hardware synthesizers. It allows for on-the-fly melodic tune creation with detailed control over each step's parameters, enabling experimental music making.

What are the key features of midiSequencer?

Key features include step sequencing with extensive parameter control (pitch, velocity, length, MIDI channel, swing, probability), chord creation, built-in MIDI FX like echo and filters, and extreme tempo control. It also supports musical ornaments for more complex patterns.

Does midiSequencer make sound on its own?

No, this app makes no sound on its own. It functions as a controller, sending MIDI data to other CoreMIDI-compatible apps or external hardware synthesizers. You will need separate synth apps or hardware to produce sound.

What devices and iOS versions are supported?

The app is universal and supports iPhone 4s and later, and all iPads. It requires iOS 8 or greater, meaning iPad 1 is not supported. To connect to external MIDI equipment, you may need a suitable iPad MIDI interface or use MIDI Network sessions over Wi-Fi.

You can create your own chords using an on-screen keyboard or select from common chord types. Each step can send out up to 128-note chords, adding a layer of harmonic complexity to your sequences.
