After a short wait Yonac bring us their new synth, KASPAR. An iOS synth that harnesses the power of 8 polyphonic synths. The synth features a new cutting edge Multi-Engine Automorphing SuperSynthesis technology. It has a total of 24 oscillators, 8 filters, 8 arps and layering abilities. In addition to extensive MIDI capabilities, Inter-App Audio, and Audiobus, it also works as an Audio Unit plug in.

Here are some the features:

  • 8 fully-featured polyphonic synth engines, each with,
    • 3 oscillators (24 systemwide total!)
    • Over 20 unique waveforms per oscillator

    • 14 types of filters to choose from
    • Dedicated filter envelope
    • Arpeggiator with multiple modes
    • Chordmaker – easily program & play chords by touching a single key
    • Powerful modulation features (see below)


  • Each synth has a dedicated mod assign matrix with 6 slots

  • 2 LFOs per synth
  • Modulation envelope
