a - In the menu bar for grain clouds, after the envelopes, is the the ? some kind of random envelope?
? switches envelope types randomly for each consecutive triggered grain, selecting a random option from the other 4 windows.
b - What comes next? Is the circle with the vertical line though it for mono, vs the next LR option, which seems to mean stereo?
pretty close! the one with the vertical line is the “unity” button, which preserves the underlying spatialization of the sampled audio file - if a stereo file is sampled, you get the stereo mix faded in/out as it is in the actual file. if the file is mono, you get a mono grain. If both mono and stereo are sampled, you get the mono mixed with the stereo.
the L/R button ping pongs the grains back and forth between left and right channels for each consecutive grain trigger. there’s a stereo “width” control on the cloud when this option is selected (constraining the ping pong effect) and a pan control for the first option.
c - what is the next option? The arrow pointing NE, the two lines, the two ‘arrows’? - No idea…
yeah this is a funky one . normally when you throw a cloud offscreen it gets deleted. this button defines the “edge behavior” or “wrap behavior,” in which clouds thrown off screen are not deleted, but wrap around to the other side of the screen instead. this is useful for more generative applications.
the arrow with the perpendicular blocking line at the end is the default mode - cloud gets deleted when going offscreen.
the zig zag sort of arrow is a “pacman” style edge wrap - the cloud will jump straight across the screen to the opposite edge from the one where it went offscreen.
the two non-parallel lines are a sort of “projected path” jump - basically the cloud continues moving along the same linear trajectory. imagine drawing a line backwards along the heading of the cloud as it’s moving - this is the path it will follow on a loop.
this feature is mainly useful when you turn on the accelerometer (with the G button) and let the clouds drift.
d - what is the next - XY with arrow pointing East, X + same arrow, Y + same arrow, NO + same arrow. Sorry if this is obvious? It isn’t to me.
speaking of the accelerometer… these are “gravity constraints” - XY means the accelerometer applies in both X and Y directions, X applies just to the X direction (so the cloud can not drift in Y), and vice versa for the Y button. NO means this cloud opts out of any gravity input. this button doesn’t have any effect if the gravity button (g in the main menu) is off.
e - and then the # before the amp envelope. I was sort of assuming this was the semitone offset for the cloud, but I don’t see how it works
yep! semitone offset. when you toggle it on, the multiplier-style pitch parameter hides and a new semitone one appears. touch the pitch param and you’ll see you are presented with some semitone guide lines. the unit for pitch also changes to “st”
Hope this helps! Sorry for the super long winded reply!
