This synth combines the STK model of a resonant stiff bar with a sampler. Overtone vibration modes of a bar are modeled with four resonators (biquad filters). Resonance, gain and relative pitch of the resonators can be set with precision. Graphic control is provided to set the volume weighting of each mode across 10 velocity bands. The sampler portion supports microtuned, non-looped playback of a .wav sample. The resonant filters, envelope, vibrato, and sampler are calculated and cross-faded per sample in a single pass.
