Whitebox has released Dialsynth, a free cross-platform instrument for Ableton Live with Max/MSP. It's a one-dial recall of 24 hidden presets ranging from rich pads to quirky leads.
Continuing the Whitebox exploration of simple one-touch instruments, Dialsynth provides an immediate solution to "where do I start on this piece of music?" The synth engine is Pluggo's Laverne teamed with a simple reverb and chorus.
Ableton Live and Max for Live (Max/MSP) are required to run this instrument.
