LH Rubbing is a polyphony software synthesizer app for iPad running on iOS 6.0 or latter.

There are three wave oscillators, one noise oscillator, two LFOs and one three type embedded filter (low-pass, hi-pass and bandpass).

Each wave oscillator can generate three kinds of waveform which are triangle, square and saw wave.

LFO can be attached to different modul for different modulation or control such as OSC Pitch, PW, Filter Cutoff Frequency, Filter Resonance and OSC Output Mixing.

The frequency and amplitude of the 1st LFO can be modified by the 2nd LFO.

Pitch, Filter Cutoff Frequency and Resonance can be controlled by the ADSR envelope generator.

The Keyboard Rubbing brings up vibrato while control the vibrato rate and depth.

Customer Reviews

Surprisingly Lush

This is actually quite a lovely synth. I've managed to program a number of useful patches/some surprisingly unique sounds. Definitely deserves more of my attention.

The responsiveness of knobs/buttons could use improvement. Some are overly sensitive, while others take several touches/long-presses in order to make the necessary changes. A value display while tweaking would be very beneficial, too.


Nothing but a little awesomness here. Very playable synth with great sounds.

Fat and original

This is another one of my favorite synths that can cut thru or wobble or create wandering evolving textures. It has an awesome interface with a killer rubbing effect(a kind of automation). This one deserves your time and is stable.peace christo
