Multimode Ladder Filter vs Beat Remixer

A 4-pole (24 dB/oct) ladder filter modeled after the topology designed by Robert Moog in 1965. Four cascaded one-pole stages with tanh saturation at input and feedback produce warm analog-style distortion that scales with drive and resonance. Five filter modes (lowpass, highpass, bandpass, notch, and resonant) cover everything from classic subtractive sweeps to sharp self-oscillating leads. Resonance drives the filter to self-oscillation at high values, generating a sine tone at the cutoff frequency. A dry/wet control enables parallel filtering.

Turn your music into a live remix. BeatRemixer lets you rearrange and perform your tracks on iPhone and iPad. Load a song, explore its eight-beat phrases, and build a new arrangement by moving, repeating, and combining your favorite sections. Keep the original track alongside your remix, jump between phrases during playback, or queue them to play in sequence. Similar phrases are grouped and labeled, making it easy to find variations and try different combinations. Add your own touch with hands-on performance controls. Loop a section, jump between beats, change tempo and pitch, and trigger effects and samples as the music plays. Features include: • Automatic BPM detection with manual tempo and beat-grid adjustments. • Drag-and-drop phrase arrangements with repeats and looping groups. • Live phrase switching and playback queues. • Beat jump pads, loop controls, pitch adjustments, effects, and samples. • Optional colored waveforms showing low, mid, and high frequencies. • Batch BPM analysis to prepare your downloaded music library. • Undo and redo, with arrangements saved automatically for each track. • Layouts designed for iPhone and iPad, in portrait and landscape. • Supports new iPhone Duo, opened and closed, in both portrait and landscape. • Record live remixes and manage recordings.
