Bandlimited wavetable-based oscillator plugins for LADSPA hosts
BLOP comprises a set of LADSPA plugins that generate bandlimited sawtooth, square, variable pulse and slope-variable triangle waves, for use in LADSPA aware audio applications, principally as components of a modular synthesis network. . 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, like a analogue-type sequencer, sync-square and ADSR envelope.
