statement

Wolkenpumpe is a live improvisation interface based on ScalaCollider / SoundProcesses / Prefuse. It is (C)opyright 2008–2020 by Hanns Holger Rutz. All rights reserved.

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.

Note that you can use this interface through Mellite.

building

Builds with sbt against Scala 2.13, 2.12, Dotty. The last version to support Scala 2.11 was 2.34.0.

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
