Stroke Machine

Stroke Machine is a professional Groove Synthesizer for the iPad.

Program your own rhythm and groove patterns and switch between them in a live performance. Mute or solo individual instruments, change parameters on the fly and record your performance as high-quality audio file for sharing or later editing on your computer.

The high-contrast user interface is perfectly suited for dim light situations on stage and assists in sound creation in the studio. Choose between a colorful and a subdued user interface skin as you like.

Stroke Machine's powerful synthesizer engine features high-quality Oscillator, Filter, Overdrive and Effect models, extremely fast Envelopes and LFO, sample-exact Pattern Sequencer and a sophisticated Sample, Sound and Pattern library.

The deep sound creation possibilities include two oscillators with typical analog waveforms and sample playback, frequency and ring modulation and a separate white and pink noise generator with integrated multimode filter. All tone generators are summed into a transient generator, followed by another multimode filter and a drive module with several types, a sample rate and bit depth reduction stage, and a two-band equalizer with shelf and bell curves.

Freely assignable modulations with an easy-to-understand user interface offer maximum flexibility easily surpassing even expensive hardware synthesizers.

Each sound is mixed into one of four effect busses, each featuring a sum overdrive, a compressor, a modulation effect like chorus, flanger, phaser or sum filter, and a space effect like delay or clocked delay, or natural, plate or non-linear reverb.
