Elsa is a retro style sampling keyboard with tempo based looping. Record, save, load, reverse samples with a multi octave on screen keyboard or plug in your core midi device of choice, soft- or hardware. Elsa comes with three built in effects, a reverb, a resonant filter and a sample rate/bit crusher. Samples are looped in three different modes, one off, forward and/or forward-reverse. The start and end of playback also comes in three modes, one set of start and stop for all, one set per note and/or one set per octave, allowing for many different types of samples. Additionally at playback time, sample length can also be controlled by a set of sample dividers, 1-8.

I have the bundle!

The controls are somewhat cryptic but once you know what they do (as the on-screen hints indicate) you will find these are very cool apps.

Searching for "Elsa"

Turns out a hilarious bounty of Disney Frozen apps. How many of those do kids need? I finally kept scrolling and found this.

I downloaded Strng after a recent interest in physical modeling synthesis without realizing that there are many more great apps you had done. And I'm quite obsessed with sample based synthesis right now (with Samplr iPulsaret iDensity etc).

This is a really lovely bit of gear. Your work deserves more attention. With this app, I feel compelled to make a new synth from every patch that I have ever made on my analog. But with every note of the scale slightly different. Really such subtlety beautiful possibilities here.

This is the kind of thing where the less than 5 star reviews made me mad so I felt the necessity to write this. Your colors are perfect by the way.

Best sampler on iOS!

This is one of my favorite iOS music apps! It's got a nice minimal a e s t h e t i c but has the ability to infinitely warp the hell out of your sample library. The drum pad setting is sick, especially if you put a few slices/hits in the same sample file and you can assign a key per hit. The FX sound great, Ableton Link support is really nice as well. The dark mode is also the bee's knees. Anyway, get this app and learn it's awesomeness!
