App News

Hi people who still read this!
Apple recently decided that old apps that haven't been updated for a while will get purged from the App Store, and three of mine are now not available: Enumero, Banshee, and Tondo.
I've actually wanted to update Tondo and Ellipsynth for some time, and they may be back at some point in refreshed form.

Banshee, I don't think anyone cared about, it had about 374 sales over its lifetime. I'll definitely reuse some of its ideas, though. I have a funny variant that says the name of the note you are playing at you!

What's doing?

Hi Folks, I haven't checked in for a while!
Here's the story:
I have a pretty good version of Droneo 1.4 in January... but it had a number of bad issues in it:
For years, the control rate calculations like evolution and patters, were done at the beginning of the buffer computation cycle. But changing the engine to AudioBus meant that the size of the buffer - and the speed at which it updates, was not under Droneo's control. So that meant that evolution would proceed at an undetermined pace.
Also, the conversion to AB also made my good old iPhone 4 hiccup with more than about 4 reeds, since it wasn't efficient enough and also maybe because the audio IO is now floating point based, which doesn't seem to bother the newer devices but might be slower on the old ones. Why do I care? because the iPhone 4 is my home entertainment system device.
Droneo 1.4 had a number of innovations that you will never see. But that won't matter becasue I'm working on
Droneo 2.0 (and abandoning Dronica, which was to be basically what Droneo 2.0 will be).
I've been going back and forth about whether to make a new app or just replace the old one since about 2011!

Anyway Droneo 2.0 is going to be pretty modern. It'll support all the iOS device sizes in portrait and landscape.
It will deliver the promise of Dronica, that is, it simplifies and empowers the features of Droneo: no limits on number of reeds, Churning, Consorts, and Mirrors are replaced with evolution between states (scaled beats), and the pace of that evolution is governed by a heartbeat. Voice banks are being replaced with a tag-based system, and old banks and patches will be legible. There'll be a tighter connection to the Droneo Voices web service, so you can post and retrieve Droneo voices to the public. I'm not sure, but I think you'll be able to stuff them in iCloud too, and pick up your own Drones on different devices.

The Tone Spiral is gaining power as it includes thousands of Scala scales as Guides. It may also be able to import and export scales from Gestrument.

The interval Spec is also expanding, adding ideas that are also in PolyHarp: for example, I have a notation that expresses a number as its prime factors, so you won't have to figure out what 3^24th is, etc. (in that case, it'll be "24;" more on that later). This makes a lot of sense if you want to quickly suss out the consonance between various intervals - you can just subtract the powers of the primes. Of course, negatives and other real numbers are allowed, ;.5 is the square root of two, for example. Polyharps' parade of roman numeral intervals (I,IV,VI#...) are also supported.

It'll be localizable, (I pity the translators...)

The wavetables (timbres) that are the heart of the synthesis are getting updated: they'll have better resolution, may contain several cycles of waves, and may also allow generating them and importing them from audio copy.

I mentioned the beats in passing, basically, a beat is a bundle of volume, pan, timbre and a passel of evolution parameters.

It'll save voices to Audiobus and also act as an IAA generator.

The instructions won't be one huge page anymore.. I'll see if I can make it so that it exists both as a web page and PDF doc. I may need to write some scripts to help me with that.

So, a lot of work! I'm about 1/4 done with it. So that'd Droneo 2.0


PolyHarp is the other main thing obsessing me. There are some corners of it that need some work still. PolyHarp builds scales out of chords, can act as a guitar, piano, multi chord strummed device with intervals plucked from hell, in 200 voice polyphony, or act as a MIDI controller.AB, IIA, etc. It is about the most powerful autoharp fantasy ever.
I want to see if I can make the internal synthesizer more efficient and powerful and sound better. It's OK so far, but I think it could be better.

Then there are fixes to AUMI, which I want to experiment with some more in terms of a motion flow tracker. fast movement is hard to track right now, I want to make the frame rate something fierce!

So that's what's going on!

AUMI! and more

On June 1, 2013, my app AUMI, written or Deep Listening Institute, went live! AUMI is a music app that tracks motion in video to trigger sounds or play MIDI.
we have great hopes that AUMI will allow severely disabled people to play music and to get some audio biofeedback, and have some fun!
Also, we, the temporarily abled, can also enjoy it. It runs on all iOs devices with front-facing cameras.

Meanwhile iOs7 is removing the way most of my synthesis apps make their audio. This probably means that people running my apps on older devices will not be able to update them (because Apple doesn't support old iOS versions too well . They think history started with the iPhone 4 and iPad (1). and that original iPad is rapidly being left behind.
So , I'll have to swap out my audio engines and get all that running .

Some apps may have to be retired out of the store, I think.

synthicity itself 1.2.1 is in the store

it's not that different, but it's a little mooe efficient and can do 64 voices if you are careful.

synthicity 1.2.1

nobody _should_ care, but there's a new synthicity coming that's a bit improved from 1.2. the main think you may notice is that it goes up to 64 voices if you have a fast enough machine and you drop that sample rate.
