Voc-Two allows you to create realistic string ensemble and choir sounds without the use of samples.
String Synthesizer is a free VST instrument emulation (no samples here!) of those string synthesizers of the late 70’s made famous by ARP and Solina. It features a full ADSR envelope generator, a small effect section with a phaser, a delay and of course the ‘ensemble’ effect.
Pling4 is a free plucked string model VST instrument with improved sustain and high frequency response thanks to hermite interpolation. The timbre is also significantly improved with a more complex pick impulse for brighter, crisper plucked string patches.
