The PLATE reverb (G_RTYPE 5: firmware/src/fx.c (the constants, plate_gain), firmware/src/fx_bus.c (rev_plate)) follows the topology, the line lengths (scaled), the allpass and feedback structure and the control laws of the reverb of the CHOMPI firmware (MIT): - firmware/chompi-tape/code/src/reverb.h and fx_engine.h (the same reverb in the TAPE, TEMPO and WAVE firmwares), which are Emilie Gillet's Rings / Clouds reverb (pichenettes/eurorack, MIT; the Griesinger plate of Dattorro's paper) in DaisySP form, and CHOMPI's own control laws (firmware/chompi-tape/code/src/DSPEngine.h: the in-loop low-pass and the diffusion at its reverb knob 0.70) - firmware/chompi-tempo/code/src/granularDelay.h and granularDelay2.h (TEMPO's granular delay: no header of its own and no third-party lineage in the files; it uses DaisySP's fonepole / fclamp helpers only): the idea of a tempo-synced delay that retriggers, reverses and shifts its repeats by an octave on a random share of the clock edges. L/RRY's DELAY MODE RAND and OCT+ (firmware/src/fx_bus.c dly_ev) is written again from that idea in integer C, no source line copied; so is the host harness tests/graindelay_test.c (which carries the notice below) Rewritten as integer C for L/RRY (Q15 coefficients, 16-bit lines at half the sample rate, the lines' lengths x 0.546, in ROOM's two buffers), 2026. The host comparison harnesses tests/revcompare_test.c and tests/graindelay_test.c follow the same sources. These files stay under the MIT licence below; the rest of L/RRY / Felucca is GPL-3.0-only (LICENSE). The name and logo of CHOMPI are trademarks of CHOMPI Club and are not covered by this licence; L/RRY's reverb is called PLATE and its delay modes RAND and OCT+, and they do not use them. ------------------------------------------------------------------------------- 1.
