Another new Hokusai update, v1.0.4, should have hit the App Store by the time you read this. It's quite an interesting one... so what have we added?
Well, the biggest "crowd-pleaser", if your emails and tweets are anything to go by, will be the per-track gain control dials. These allow you to set the volume level of each track, nondestructively. You can also double-tap them to mute a track.
For screen-space reasons, the dials only appear when you've zoomed in vertically. A little tip: you can still access mute while zoomed out, though — double-tap the mono/stereo speakers.
(Oh, and you've always been able to solo — when a region is selected, that track is soloed. It's even more convenient if you enable the "Double tap to select" gesture in the system settings.)
Note that mute and gain control are Pro Pack only features!
Also new to the Pro Pack are a couple more filters: the classic Phaser effect, and — since a few folks asked for it — a click track/metronome generator.
We've also upgraded the Time Stretch and Pitch Shift filters, to add high quality (DIRAC LE) processing. The default setting is to work the same way as before (as the old method is much faster!) but you can simply enable High Quality mode for slower, but much nicer, results. Note that DIRAC LE only works between 0.5x and 2.0x speed/pitch adjustment, so if you set the adjustment outside this range, the high quality option will be disabled and it'll use the old method.
This one gets its own section, because it's my personal favourite :)
Many effects in Hokusai have sliders to set their properties. And many of those sliders are what we refer to as "multisliders", meaning that you can set more than one value for them. The filter then adjusts the value while processing, starting with one value, and ending on the other (or oscillating between them). For instance, you can use this with the pitch setting in the synthesiser to generate a rising, falling or warbling tone.
We've upgraded this so that as well as start/stop or oscillating values, you can actually fingerpaint custom changes. Pick fingerpaint mode and the slider is replaced by a tiny graph showing how the value changes over time. Tap this to see a much larger view (full screen on iPhone, "pretty big" on iPad) that you can edit.
Here's a demo, showing the various multislider modes, including the new Fingerpaint:
