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.

Price/Quality misaligned

Occasionally an inexpensive app proves to be indispensable and it restores your faith in cheap apps, which is then disappointed by buying many useless cheap apps hoping each will reward your willingness to invest in them but instead just use up memory.
Given the price you might assume that there is a bigger, better app to do what this one does. There isn’t. Now w/ AUv3 support this is the bigger, better app. Nothing else does strings like this. Laplace is closest but, as it’s not focused on strings it does not give the explicit control over string parameters the way this app does. I cannot replicate the sound with anything else.
This should cost $10-$15 if compared to similar quality apps.

One of my most used synth apps

I think I paid $3 for this app, but it’s easily worth $20. Simple intuitive interface reminiscent of the op-1 string synth. I love the new update, excited to try the rest of the bundle. Thanks dude I love your work!

I have the bundle!

The controls are somewhat cryptic but once you know what they do (as the on-screen hints indicate) you will find these are very cool apps.
