Stroke Machine iPad Groove Sequencer (Teaser)

the-stroke-machine

Wolfram Franke (Waldorf) has introduced a new groove synthesizer for iPad, Stroke Machine.

Stroke Machine’s high-contrast (even garish?) user interface is designed for usability, especially for performance in ‘dim light situations’.

Stroke Machine’s synthesizer engine features Oscillator, Filter, Overdrive and Effect models, fast Envelopes and LFO, sample-exact Pattern Sequencer and a Sample, Sound and Pattern library.

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.

Here’s a sneak preview video for Stroke Machine:

Overview:

  • 12 drum and percussion sound parts
  • 12 melodic sound parts
  • number of voices only limited by CPU
  • 4 multi-effect busses
  • pattern with up to 8 bars and 16th resolution, bar nominator and denominator freely adjustable
  • swing
  • modulation sequencer for smooth or quantized automation of each continuous sound and bus parameter
  • 128 patterns including all sounds in direct access
  • track solo and mute
  • sample import
  • audio export of a pattern or the whole performance
  • AudioBus support
  • WIST support

Per voice:

  • 2 oscillators with waveforms sine, triangle, sawtooth, pulse with pulse width modulation
  • sine waveforms can be changed in slope, symmetry and saturation for additional overtones
  • sample playback
  • frequency modulation of each oscillator by white noise and oscillator 1 by oscillator 2
  • ring modulation
  • noise generator with white and pink noise, variable density and multimode filter
  • transient generator with crack, rattle, spike, click and thump generators
  • multimode filter with 6 dB low or high pass, 12 dB and 24 dB low, band or high pass and band stop
  • drive stage with light, medium, hard, clip, tube and fuzz overdrive and tone control
  • redux stage (decimator) with sample rate and bit reduction
  • fully parametric two-band equalizer with shelf and band types
  • glide generator with portamento and glissando for melodic sounds
  • voice allocation poly, mono and 3 alternate groups
  • 1 LFO with waveforms sine, triangle, pulse, positive pulse, sawtooth, 4 step ramp, 8 step ramp, sample & hold, random, rate synchronizable to clock
  • 2 Envelopes with (ADSR) or without (2 decay stages with breakpoint) sustain and variable slope for each stage
  • modulation sources LFO, envelope 1 and 2, velocity, note number, 4 random generators, pitch bend and modulation wheel
  • any continuous parameter can be modulated
  • voice mixed into one of four effect busses

Per effect bus:

  • sum drive stage with various types and tone filter
  • compressor
  • modulation effect with 2 to 6 stage chorus, 4 to 12 stage phaser or multimode filter
  • space effect with stereo modulation delay, synchronizable to clock, natural, plate, or non-linear reverb

Minimum requirement: iOS 6.0

Stroke Machine is available in the App Store for US $14.99.

  1. This looks very powerful and extensive but that 30 odd second teaser doesn’t sound that different to lthe other drum synthesis machines on iOS, in my opinion.
    I would like to see and hear more in depth demos for this and the option to change that ‘challenging’ colour sheme.

  2. nothing wrong with bright colors in a UI but at least be consistent. this looks like it was an attempt to use every color in the picker….

  3. I wouldn’t be put off by the color scheme. I just purchased it based on the reputation of the developer and so far it sounds fantastic. I’ll have to use it for a while to give it a fair review, but I can already tell there is quite a bit of sonic capability. High quality set of stock samples to play with straight away as well.
