Sometimes you need to count or tally things. This simple app increments or decrements a counter, automatically or manually, while saying the number aloud. It uses an algorithm to choose different variants of the number sounds, so it's somewhat better sounding than text-to-speech. It counts forward or backward automatically by any integral increment, and can count up to 999,999,999 if you're willing to wait 31 years or so. But it gets more interesting than that. Enumero counts in Latin, binary, hex and morse code. Enumero counts in grey code, picks random numbers and can trip off the first 10,000 digits of Pi (in hex and binary too). Enumero can recite the names of chemical elements. It can play the toy piano, sing a little Solfege and regale you with the very interesting Nerve Events. it can iterate through all possible orders of orders, and play them as a diatonic scale. It can also make up its own words out of bits of phonemes in three different ways. No other app can claim these features! And now Enumero also can be run in Audiobus and Inter App Audio, so you can use it as a random voice in musical compositions. Check out http://www.jhhl.net/iPhone/Enumero.

EchoSketch turns delay and reverb into a live, playable instrument. Shape your sound in real time using a responsive X/Y performance surface designed for intuitive touch expression. At its core are four great-sounding delays: digital, analog, ping-pong, and reverse. The range for each parameter and the XY axes direction can be set independently, allowing you to easily morph between sounds. It works as an Audio Unit plugin or standalone — iOS or Mac. Comprehensive Delays • Digital (patterned after a legendary '80s rack delay), Analog (warm, with tape-style pitch glide), Reverse, and Left/Right Ping-Pong • Delay times can sync to tempo or be set in milliseconds • Feedback features delay-dependent tone shaping — bright for short delays and darker for long ones Convolution Reverb • Stereo or mono Spring, Plate, and Hall • Reverb path is separate from the delay (same as vintage tape echo units), so repeats don’t get washed out Modulation and Filter • Analog-style modulation for chorused, warbly pitch echoes • Tone control — darken or brighten delays, with a center detent for flat Designed for Hands-On Performance • HOLD / LIFT — leave the XY cursor in place, or touch the pad for momentary delay sounds • FREEZE — set the current feedback into an infinite loop and play over it • MOTION — record a gesture on the XY pad and loop it Presets and More • Presets are transferable between hosts • Two looks — light "Trail" and dark "Glow" • Works standalone with live audio or as an AUv3 plugin • Universal — iPad/iPhone also gets you the Mac version — one purchase • Mac: after installing, open EchoSketch once to use it as a plugin in your DAW • Works in AUM, AudioBus, GarageBand, Logic, and other AUv3 hosts
