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

Enso is a looper. Not a phrase sampler, not a beat slicer: a real looper, built in the image of the pedal loopers and reel-to-reel tape systems that defined the form, then extended well past what hardware can do. Press one button and it records; press it again and you are looping. Up to five minutes of stereo audio, host-synced or free-running. The play and record heads are completely decoupled, each with its own through-zero speed control from -4x to +4x. Play backwards at half speed while overdubbing forwards at double, and things get strange in the best way. Four sectors give you separate loop regions to crossfade between and overdub within, and a built-in effects section (tape-style saturation and hiss, filters, and chorus) can sit in the feedback path so your loop ages like tape with every pass. Enso runs as an AUv3 plugin in your favorite host, and includes a standalone mode for sketching. FEATURES - Full automatic looping engine: simple to learn, exceedingly powerful, with one-button looping control, both host-synced and free time. - Independent play and record heads: through-zero speed from -4x to +4x on each, with selectable increment and decrement values. - Dub In Place: work like a traditional digital looper, or like a tape looper with the effects and speed changes in the feedback path. - Sector crossfading: define four start and end points, crossfade between them, and overdub or re-record within them. - Effects section: tape-style saturation and hiss, high- and low-pass filters, and a stereo chorus. - MIDI Slice mode: play your loop from a MIDI controller, automatically sliced into 4 to 16 equal pieces. - Full MIDI CC implementation: an assignable MIDI CC page covers most of the looping engine, tuned for foot control. - Auto RTZ: automatically return to zero at a chosen interval to keep loose material in sync. - Cross-platform preset format: XML presets that can store the buffer, compatible with the desktop version of Enso. No subscriptions and no nonsense. Buy it once and it is yours, with free updates. Enso is also available for Mac, Windows, and Linux at audiodamage.com.
