OFX_ChainPreset

Extension

Description

OFX_ChainPreset can store presets for OFX_Chain objects: A setting includes which functions are active (by name), and separate parameter settings for each active function.

First code examples:s.boot; // first, prepare for making a proxy chain: ( // some sound functions - first a test source, ( // add a sound source OFX_Chain.add3( \dust, \mix -> { |dens=20, dustdec=0.02, dustfreq= 600| Ringz.ar(Dust2.ar(dens).lag(0.0001), dustfreq, dustdec) }, 0.2, [ \dens, [0.1, 1000, \exp], \dustdec, [0.0001, 0.1, \exp], \dustfreq, \freq ] ); // ... and then some effects to use in the chain OFX_Chain.add3( \ringmod, \filter -> { |in, randrate=5| in.asArray[0] // force mono inputs * SinOsc.ar(LFNoise0.kr([randrate, randrate]).exprange(300, 3000)).sum }, 0.5, // wet/dry mix of 50/50 [ \randrate, [0.5, 50, \exp] ] ); OFX_Chain.add3( \dist, \filter -> { |in, drive=10, amp=0.2| (in.asArray[0] * drive).tanh * amp }, 1, // all wet, just the dito [ \drive, [1, 100, \exp] ], ); OFX_Chain.add3( \comb5, \filterIn -> { |in, drive=10, amp=0.2| (in.asArray[0] * drive).clip2(0.5) * amp }, 0.2, [ \drive, [1, 100, \exp] ], ); OFX_Chain.add( \ampFin, \filter -> { |in, drive=1, limit=1| Limiter.ar(in * drive, limit) }, 1, [ \drive, [1, 100, \exp], \limit, [0.1, 1.0, \exp] ] ); ); // now make a proxy chain and gui for it c = OFX_Chain(\alpha, [\dust, \ringmod, \dist, \ampFin]); c.play; // play the proxy g = c.gui(12).moveTo(0, 800); // 2. make a OFX_ChainPreset for c b = OFX_ChainPreset(c); // declare ampFin as always untouched / not to be stored b.exceptedSlots = [\ampFin]; ) b.slotsToStore; // these slots and their values will be stored when active c.activeSlotNames; // these are currently active c.add(\dust, 0.5); c.add(\ringmod, 1); c.activeSlotNames; // these are currently active b.addSet(\test1); b.settings.list; // repeat unil you find one you like c.proxy.setUni( *c.proxy.controlKeys.collect ( [_, 1.0.rand] ).flat ); b.addSet(\test2); b.settings.prettyList; // two entries // add a slot and add a setting c.add(\dist, 1); b.addSet(\test3); // remove another and addSet c.remove(\ringmod); b.addSet(\test4); c.remove(\dist); c.proxy.set(\dustfreq, 3000, \dens, 7, \dustdec, 0.01); b.addSet(\test5); // now you have 5 different settings - switch between them: b.settings.prettyList; b.settings.names b.setCurr(\test1); b.setCurr(\test2); b.setCurr(\test3); b.setCurr(\test4); b.setCurr(\test5); // now write them to disk b.settings.write; b.settingNames;

Examples

Here is a quick and dirty gui sketch for a OFX_ChainPresetGui, assuming you still have b and c preset from above around:// assumes OFX_ChainPreset b is still around // writing alpha to disk will store here: b.settings.storePath; b.settings.filename; // set the dirpath to something else: b.settings.dirpath; ( w = Window("PCPre", Rect(0,600,500,500)).front; w.addFlowLayout; e = EZPopUpMenu(w, Rect(0,0,150, 20), \pcPre, b.settingNames, { |ez| b.setCurr(ez.item) }, labelWidth: 50); [ \sto, { |but| b.settings.storeDialog('???', b.getCurr, but.absoluteBounds.center, // store settings to disk? { b.settings.write } ) }, \del, { |but| b.settings.deleteDialog( but.absoluteBounds.center, // store settings to disk? { b.settings.write } ) } ].keysValuesDo { |key, fun| Button(w, Rect(0,0,60,20)).states_([[key]]) .action_(fun) }; g = OFX_ChainGui(c, 20, w); // update e when stored names change: q.pcpSkip = q.pcpSkip ?? { SkipJack({ var newnames = b.settings.names; if ( (newnames == q.pcpNames).not) { e.items = newnames; } }, 0.5, w.isClosed); }; )

An example of a OFX_OutputFX / OFX_ChainPreset combination, using the same sound functions as above:m = OFX_OutputFX(s, 2, [\dust, \ringmod, \dist, \ampFin]); n = OFX_ChainPreset(m); n.exceptedSlots = [\ampFin]; // quick and dirty copy of the settings n.settings.list.addAll(b.settings.list); n.settings.names; n.setCurr(n.settings.names.choose.postcs); n.setCurr(\test2); n.setCurr(\test3);
