Strng is a string synthesiser inspired by the karplus-strong algorithm. The physical modelling starts with a short burst of noise that then guided by a tuned delay buffer and string tension filter, generates plucked string like sounds. No samples are used. Strng is 16 voice polyphonic and can be controlled with an in app 25 key chromatic keyboard or connect prefered midi controller through USB or Wifi. To further shape the sound two post effects are available, a ping-pong stereo delay and two channel resonant filter controlled by two LFOs. Connect to other apps through AudioBus, inter app audio or load in DAWs as AUv3. +++ String synthesis engine +++ 16 voice polyphonic +++ Audiobus, IAA and AUv3 +++ Core MIDI, bluetooth midi and limited MPE +++ 25 multitouch keyboard with aftertouch control +++ Factory presets, save and load your own settings, drag'n drop from files app +++ Aftertouch modulation for attack, sustain, bit crush, resonant filter and detune lfo +++ Stereo ping-pong delay +++ Two channel resonant low pass filter LFOs
