Sinevibes has updated its Circuit multi-band waveshape modelling Audio Unit plugin.

Changes in v1.0.3 include:

• New LFO rate display design with "rotating arc" cycle indicator.
• Fixed LFO waveform selector setting undefined value when pointer was dragged too far right.
• New effect presets.

The update is free to all existing users, and is available for $29 to new customers.

Additionally, Sinevibes has published two new sound design tutorials for Circuit:

• Circuit on drum beat: in this tutorial you will learn how to process a house beat loop consisting of synthesised kick drum, clap, hi-hat, and vinyl noise.
• Circuit on synth bass: in this tutorial you will learn how to process a simple synth bass made out of two square waveforms.

These tutorials include full interface walkthroughs, audio examples, as well as source sample downloads.
