Standard Opcodes

lorisread ktimpnt, ifilcod, istoreidx, kfreqenv, kampenv, kbwenv[, ifadetime ]

Import a set of partials from an SDIF file, applying control-rate frequency, amplitude, and bandwidth scaling and store the modified partials in memory.

lorismorph  isrcidx, itgtidx, istoreidx, kfreqmorphenv, kampmorphenv, kbwmorphenv

Morph two stored sets of bandwidth-enhanced partials and store a new set of partials representing the morphed sound.

ar lorisplay ireadidx, kfreqenv, kampenv, kbwenv

Render a stored set of partials applying control-rate frequency, amplitude, and bandwidth scaling envelopes.
