proaudio BLOP comprises a set of LADSPA plugins that generate bandlimited sawtooth, square, variable pulse and slope-variable triangle waves, for use in LADSPA hosts, principally for use with one of the many modular software synthesisers available. They are wavetable based, and are designed to produce output with harmonic content as high as possible over a wide pitch range. Additionally, there are a few extra plugins to assist in building synthesis networks.
