Fun and overlooked

I have owned most of the matrix sequencers in this class including the expensive ones. There were honestly just too many to try them all and I had to draw the line somewhere. I wish I had picked this one up a couple of years back. I bet I would have had fun with it. It does not seem to have some of the modern features I would consider necessary for my workflow but it you are on a budget and want to try one of these grid style pattern sequencers, this one has some useful capabilities. With a bit of love from the developer this could be a nice alternative to the rather expensive apps that it is similar to. Seeing as how it hasn't had an update since 2011 I am not sure we will see that.

i want to like this app

This app is o.k.
There's a nice feature that shows "ghost impressions" of all the notes being played. So often with these synth composing programs, you hear what you've programed, but you have to be on the right screen to see where it's coming from.

Editing notes is difficult. How you physically place the notes on the "dots" is way too small. I spend more time adding and deleting wrong notes just because the touch size is so tiny. Very frustrating, I would like this app a lot more if i could just tap the note i want without having to tap it 8 more times to delete and re-enter all the mis-taps. You need miniature fingers to program this synth.

2nd, the tone. The instruments sound alright. Pretty electronic. But there really aren't very many choices.

The layers are confusing. It keeps switching between layers when editing and playing, and i still don't know why? While editing layer one, I'll swipe up to a different instrument (a feature i like a lot), but somehow the layer will change to layer two?

isequence, isyn, and/or electron are still my top three synth composing programs.

Having a lot of fun with this.

A well-designed musical tool that is more complex than it appears at first glance. For instance, the ability to set loop ranges for each pattern means being able to play a 7 note sequence on top of 12 if so desired. There is a nice selection of instruments available, but of course I want more. (Note to developer: how does one access the web interface mentioned in the description, in order to create instruments?)

Another example: adjustable feedback and timing of the delay effect, either in milliseconds or in multiples of a 32nd note ... and fractional multiples if you want. 😎

Very glad to have found this gem.
