New Silencio patches based on Faust examples

[gogins]

I have finally got Csound's Faust opcodes running on my system. I have explored some of the Faust examples in their Web IDE, and I see that a few of the patches are superior to similar Csound patches.

• [x] Find out how to adapt Faust examples and other Faust code to Csound instrument definitions using the Silencio pattern.
• [x] Identify a some of the better Faust examples, those best suited to my style of composition, and get them working as Csound instruments. On investigation, most of these do much the same as Csound equivalents. The best ones are bells and such with no pitch control.
• [x] See if Faust's spatialization is better then mine, if so replace mine with Faust's in silencio. No, Faust's spat is not periphonic.
• [x] See if Faust's UI runs standalone from Csound instrument definitions. No, the Faust UI is abstract unless it is compiled to a specific architecture.

Faust examples to evaluate:

• [x] The greyhole reverb sounds good and does some more exotic things.
• [x] JPRev also sounds pretty good.
• [x] FMSynth2. Done.
• [x] modularInterpInstr. Done.
• [x] turenas, possibly usable, especially in limited range. Done.
• [x] NLFfm -- nice, has frequency control. Done.
• [x] djembeMIDI, very limited control over frequency, nice hand drum sound. Done.
• [x] rain, Sounds great, but has no control for changing pitch. Will try tunable bandpass or resonant filter. Done with svfilter.
• [x] wind, Sounds great, but has no control for changing pitch. Will try tunable bandpass or resonant filter. Done with svfilter.
• [x] bubble, sounds great and has pitch! Done.
• [x] germanBell -- nice. Figured out how to get this to work. Sounds great, has no frequency control. Done.
• [x] churchBell. Sounds great, but has no control for changing pitch. Done.
• [x] frenchBell. Sounds great, but has no control for changing pitch. Not doing, I have enough bells.
• [x] englishBell. Sounds great, but has no control for changing pitch. Not doing, I have enough bells..
• [x] russianBell. Sounds great, but has no control for changing pitch. Not doing, I have enough bells..
• [x] brassMIDI. As with STK brass doesn't actually sound very good. Not doing.
• [x] ControllableNonPhysicalString -- nice. No frequency control. Not doing.
• [x] HammeredString -- nice. Sounds good, has no frequency control. Not doing.
• [x] WaveSynth, redundant with Csound. Not doing.
• [x] drums, no frequency control, but sounds good. Not doing at this time.
• [x] PianoHammeredString, Sounds good, has no frequency control. Not doing.

The faustcompile opcode will usually required options similar to "--import-dir \"/home/mkg/faust/libraries\" -lv 1", 1. Note that the -vec option did not work for this example.

All performance control will normally be implemented using UI controls, which are abstract unless compiled for certain architectures. Here's a complete orchestra:

gi_faust_compiled faustcompile {{
declare name "GermanChurchBell";
declare description "German church bell physical model.";
declare license "MIT";
declare copyright "(c)Romain Michon, CCRMA (Stanford University), GRAME";

import("stdfaust.lib");

process = pm.germanBell_ui <: _,_;

}}, "--import-dir \"/home/mkg/faust/libraries\" -lv 1", 1

print gi_faust_compiled

instr 1
i_faust_dsp faustdsp gi_faust_compiled
faustctl i_faust_dsp, "strikePosition", 2
faustctl i_faust_dsp, "strikeCutOff", 65000
faustctl i_faust_dsp, "strikeSharpness", .5
faustctl i_faust_dsp, "gain", .5
faustctl i_faust_dsp, "gate", k(1)

a_left, a_right faustplay i_faust_dsp
outs a_left, a_right
endin

Questions:

• [x] What is "MIDI-enabled?" _It means MIDI data is bound to UI elements, see https://faustdoc.grame.fr/manual/midi. But this is not relevant here, where Csound binds MIDI data to pfields.
• [x] Do MIDI-enabled objects take real values? Yes.
• [x] What determines the name of a UI control? The label, but the label can have embedded metadata (I would say rather, attributes).
• [x] Do the Faustgen opcodes support multiple Faust compilations? Yes, the handle appears to be a simple index into a table of compiled objects.

I an closing this issue and opening a new one for a general maintenance of the patches.
