Polyphonic Synthesizer

for Mac/Windows ($24,99)  and iPad ($7,99)  

A versatile, morphable polyphonic synthesizer.

Your new guilty pleasure.

Syndt is a high quality polyphonic synthesizer with a lot of possibilities. The oscillator waveform can be morphed between pure sine to pure square, and supports altering of pulse width. Both the shape and pulse width can be modulated by two independent LFOs. With fine-tuned low pass and high pass filters combined with a separate filter attack setting, (optionally based on velocity) this synth can create some raw and interesting sounds. The additional LFO can be shaped exactly as the oscillator, and optionally controls filters, gain and pitch (using a modulation wheel or just automatically). This LFO can be synchronized to a AUv3 host. Globally there’s a nice stereo chorus, ping pong stereo delay (that also can sync to a AUv3 hosts BPM) and EQ.

  • 1. Oscillator

    This XY Pad sets the wave shape. X axis: pulse width (pure sine to the left, short pulse width to the right). Y axis: morphs between pure sine and square.

  • 2. LFO & more

    A powerful LFO + Delay, Chorus & EQ lies under these tabs.

  • 3. Mini LFO:s & Filters

    These sliders affects the oscillators values. These LFO only output pure sinewaves. If the NOTE ON SYNC is ticked, the LFO will be reset on a new note. If not, it will keep on going. HP & LP Filters with separate resonance control.

  • 4. ADSR

    Controls the Attack time, Decay time, Sustain level and Release time of the voice.
