Sequle is musical scales based sequencing app. It uses musical scales theory to produce notes for MIDI-interface.

It has six tracks with note lengths, velocities and transpose. Tracks can have invidual pattern lengths and speeds. Song mode for more melodic performances. Minor and major scale and global transpose. It can be clocked either internally or from MIDI clock.

Using scales instead of specific notes makes everything sound good and it gives you more space to just play with the sounds get inspired easily.
Use note length and velocity to create rhytmical melodies. Vary pattern length to create polyrythmic sequences.

This app works with Camera Connection kit and most of the USB->MIDI converters.

The app is free to download but it has a limited playing time. You can purchase the full version with in-app purchase option and support the development.

Absolutely no reason to even try this. No midi configuration options. Horrible UI. If you’re looking for a midi sequencer, get Genome for a grid based seq, or Quantum for an analog style seq. Skip this one... insta-delete.

Developer Response ,

I'm really sorry for the disappointment.

I really would appreciate if I could discuss about the MIDI configuration scenario with users, I really don't find any need for that when using external MIDI gear. You can change the MIDI channel from the config-screen so you can set the correct MIDI channel easily. I know that is MIDI device selection is missing but I cannot find any use for it. Please contact me thru the support website if you have needs / ideas for this!

I personally think Genome and Quantum are for different kind of use. I have them both and they are great apps!

UI style is probably matter of taste, however I tried to make it really accessible and fast to use.

Sorry again if the app caused disappointment.
