You'll find the following:
# Avnet Board PolyDaWG/8 Synth Details and Source
8 voice Polyphonic Karplus-Strong string physical model synth redesigned for the small Avnet Spartan-3A development board.
# GateMan I FPGA MIDI Monosynth
Linear Arithmetic Subtractive Monosynth, 4 NCOs with 4 waveforms each. This is the first version of the GateMan synths.
# GateMan II & GateMan III FPGA MIDI Monosynths
Linear Arithmetic Subtractive Monosynth, 4 NCOs with 4 waveforms each. GateMan II contains a state variable filter which replaces the simple IIR filter in GateMan I. GateMan III is also described, the major difference being better use of RAM and fewer flip flops in the design.
# Digital Waveguide Information
General digital waveguide information plus 8 voice Polyphonic Karplus-Strong string physical model synth for Spartan-3E Starter Kit development board
# GateManPoly
Linear Arithmetic Subtractive Polysynth (8 voice), 4 NCOs per voice, each NCO supports 4 waveforms.
# PolyDaWG8 on Spartan-3A DSP.html
Test port of PolyDaWG8 on Spartan-3A DSP 1800 Development Board.
# Xarp-56
Xarp-56 (pronounced 'harp fiftysix') is a 56 voice physical model using the Karplus-Strong string model. Each of the 56 strings is implemented as an individual digital waveguide and not multiplexed/reused as in the PolyDaWG synths.
