This is Wolkenpumpe 6th generation. Generation 5 was based on the old non-tracing Sound Processes version. Generation 4 was based on SuperCollider and SwingOSC, see sourceforge.net/projects/tintantmare. Generation 3 was solely based on SuperCollider. Generation 1 or 2 was based on Max/MSP.

mouse control

  • wheel zooms
  • right-click auto zooms
  • shift-press starts rubber-band selection
  • double-click on panel brings up generator dialog
  • double-click on edge brings up filter insertion dialog
  • double-click on scan-out brings up filter append dialog
  • double-click on node fixes/unfixes position
  • alt-click on node deletes node
  • shift-drag from scan-out brings up connector rubber-band
  • shift-drag on parameter allows to find target value before releasing mouse. While you are dragging, you can press 0 to 9 to select a gliding time (0 = default = no gliding). Pressing a number twice adds randomisation to the gliding time. A rotary knob in the bottom right corner indicates the current gliding time. When gliding is used and the mouse is released, the parameter approaches the target value with a ramp of a duration given by the gliding time. Press Escape to abort a shift-drag.

keyboard shortcuts

Global:

  • 1 zoom 100%
  • 2 zoom 200%
  • O pan to next collector (O is for output)
  • Control-Shift-F toggle full-screen
  • Escape cancel on-screen dialogs
  • Enter new-generator prompt. Start typing the name of generator, this also finds parts of hyphenated names.

Dialogs:

  • Control-Enter commit

Scan-out:

  • custom filter insertion short-cuts via object attribute with key Nuages.attrShortcut or "nuages-shortcut" and value being a string object such as "X" or "shift P".
  • Enter new-filter append prompt
  • Shift-Enter new-collector append prompt. Start typing the name of the filter, this also finds parts of hyphenated names.

Edge:

  • Enter new-filter insertion prompt

Parameter values:

  • n minimum
  • c center
  • x maximum. If parameter is amp or gain: type twice fast (prevents erroneous activation)
  • r random. If parameter is amp or gain: type twice fast (prevents erroneous activation)
  • R multi-channel random. If you used more than one generator channel, this opens up the multiple channels of the parameter. If parameter is amp or gain: type twice fast (prevents erroneous activation)
  • [ decrement
  • ] increment
  • { decrement random inter-channel spread. If you used more than one generator channel, this opens up the multiple channels of the parameter.
  • } increment random inter-channel spread
  • Enter opens dialog to enter numeric parameter value
