土曜日

MIDIReceiverから始めましょう。構造はポリフォニックになっているため、 mLast変数は必要ありません。 MIDIReceiver.hから、初期化とゲッターを含むmLastVelocity 、 mLastNoteNumber 、 mLastFrequencyを削除します。 getLastNoteNumber 、 getLastFrequencyおよびgetLastVelocity noteNumberToFrequencyも削除しnoteNumberToFrequency 。念のため、クラスは次のようになります。

 class MIDIReceiver { private: IMidiQueue mMidiQueue; static const int keyCount = 128; int mNumKeys; // how many keys are being played at the moment (via midi) bool mKeyStatus[keyCount]; // array of on/off for each key (index is note number) int mOffset; public: MIDIReceiver() : mNumKeys(0), mOffset(0) { for (int i = 0; i < keyCount; i++) { mKeyStatus[i] = false; } }; // Returns true if the key with a given index is currently pressed inline bool getKeyStatus(int keyIndex) const { return mKeyStatus[keyIndex]; } // Returns the number of keys currently pressed inline int getNumKeys() const { return mNumKeys; } void advance(); void onMessageReceived(IMidiMsg* midiMessage); inline void Flush(int nFrames) { mMidiQueue.Flush(nFrames); mOffset = 0; } inline void Resize(int blockSize) { mMidiQueue.Resize(blockSize); } Signal2< int, int > noteOn; Signal2< int, int > noteOff; };

MIDIReceiver.cppのadvance機能を変更します。

 void MIDIReceiver::advance() { while (!mMidiQueue.Empty()) { IMidiMsg* midiMessage = mMidiQueue.Peek(); if (midiMessage->mOffset > mOffset) break; IMidiMsg::EStatusMsg status = midiMessage->StatusMsg(); int noteNumber = midiMessage->NoteNumber(); int velocity = midiMessage->Velocity(); // There are only note on/off messages in the queue, see ::OnMessageReceived if (status == IMidiMsg::kNoteOn && velocity) { if(mKeyStatus[noteNumber] == false) { mKeyStatus[noteNumber] = true; mNumKeys += 1; noteOn(noteNumber, velocity); } } else { if(mKeyStatus[noteNumber] == true) { mKeyStatus[noteNumber] = false; mNumKeys -= 1; noteOff(noteNumber, velocity); } } mMidiQueue.Remove(); } mOffset++; }

ここでは3つのことが変更されました。

mLastメンバーがmLast
いずれかのキーが押されると、 noteOnシグナルnoteOn生成されます（ノート番号はmLastNoteNumberと異なってはいけません）
また、任意のキーを放したときにnoteOff信号noteOff生成されます（ノート番号はmLastNoteNumberと等しくないはずmLastNoteNumber ）

SpaceBass.hに渡します。ここでは、次のものを削除する必要があります。

Oscillator.h 、 EnvelopeGenerator.hおよびFilter.hの #include "VoiceManager.h" 、代わりに#include "VoiceManager.h"記述します
mOscillator 、 mEnvelopeGenerator 、 mFilter 、 mFilterEnvelopeGeneratorおよびmLFO
filterEnvelopeAmountおよびlfoFilterModAmount
メンバー関数onNoteOn 、 onNoteOff 、 onBeginEnvelopeCycle 、 onFinishedEnvelopeCycle

コードは見た目が良いですね。プラグインクラスは、 VoiceManagerとのVoiceManager相互作用しなくなりVoiceManager 。
privateセクションに追加します。

 VoiceManager voiceManager;

SpaceBass.cppのクラスコンストラクターを変更します。

 SpaceBass::SpaceBass(IPlugInstanceInfo instanceInfo) : IPLUG_CTOR(kNumParams, kNumPrograms, instanceInfo), lastVirtualKeyboardNoteNumber(virtualKeyboardMinimumNoteNumber - 1) { TRACE; CreateParams(); CreateGraphics(); CreatePresets(); mMIDIReceiver.noteOn.Connect(&voiceManager, &VoiceManager::onNoteOn); mMIDIReceiver.noteOff.Connect(&voiceManager, &VoiceManager::onNoteOff); }

mMIDIReceiver 、プラグインクラスではなくVoiceManagerに接続されました。 EnvelopeGenerator VoiceManagerクラスとVoiceクラスによって管理されるようになったため、それらをConnect()フックしなくなりました。
今、コンパイラは誓います ProcessDoubleReplacingは、削除したばかりのものを指します。新しい実装は非常に簡単です。これはVoiceManager::nextSampleへのVoiceManager::nextSample ：

 void SpaceBass::ProcessDoubleReplacing( double** inputs, double** outputs, int nFrames) { // Mutex is already locked for us. double *leftOutput = outputs[0]; double *rightOutput = outputs[1]; processVirtualKeyboard(); for (int i = 0; i < nFrames; ++i) { mMIDIReceiver.advance(); leftOutput[i] = rightOutput[i] = voiceManager.nextSample(); } mMIDIReceiver.Flush(nFrames); }

オシレーター、エンベロープジェネレーター、フィルターとの相互作用がすべて消えていることに注意してください。
Reset()本体では、これらのコンポーネントにアクセスできなくなったため、 VoiceManagerですべてのコンポーネントのサンプリングレートを変更する必要があります。

 void SpaceBass::Reset() { TRACE; IMutexLock lock(this); double sampleRate = GetSampleRate(); voiceManager.setSampleRate(sampleRate); }

setSampleRateはまだ実装されていません。VoiceManager.hヘッダーの publicセクションに追加します。

 void setSampleRate(double sampleRate) { EnvelopeGenerator::setSampleRate(sampleRate); for (int i = 0; i < NumberOfVoices; i++) { Voice& voice = voices[i]; voice.mOscillatorOne.setSampleRate(sampleRate); voice.mOscillatorTwo.setSampleRate(sampleRate); } mLFO.setSampleRate(sampleRate); }

基本的に、この関数は、各音声および各コンポーネントに対してsetSampleRateを呼び出すだけです。 Oscillator::mSampleRate静的に呼び出すことができますが、それでも各音声の両方のオシレーターに対してupdateIncrementを呼び出すupdateIncrementがあります。しかし、私の意見では、最初のオプションはより透明です。

インターフェイスハンドルが機能しないことを除いて、すべてが正常になりました。しかし、それらを完成する前に、オシレーターのトーン変調を追加しましょう。

トーン変調

これまで、リファクタリングはほとんど構造的でした。コードの一部をプラグイン構造の別の部分に移動し、不要な部分をすべて削除しました。私はこの時点までトーンの変調を延期しました、なぜならそれはポリフォニーとは何の関係もありません;私はすべてを1つの山に入れたくありませんでした。

関数Voice::nextSample return直前に以下return追加します。

 mOscillatorOne.setPitchMod(mLFOValue * mOscillatorOnePitchAmount); mOscillatorTwo.setPitchMod(mLFOValue * mOscillatorTwoPitchAmount);

ご覧のとおり、トーンのモジュレーション値は、GUIノブに関連付けられたパラメーターの値を掛けたLFO値によって決まります。
Oscillator.hのprivateセクションに追加します。

 double mPitchMod;

そして、コンストラクターの初期化リストに：

 mPitchMod(0.0),

publicセクションでは、セッターが必要です。

 void setPitchMod(double amount);

Oscillator.cppに関数自体を記述します。

 void Oscillator::setPitchMod(double amount) { mPitchMod = amount; updateIncrement(); }

トーンの変調値を設定することにより、再生周波数自体を変更するため、 updateIncrementを呼び出す必要があります。そして、この関数内では、何らかの形でmPitchModを考慮する必要があります。 updateIncrement書き換えましょう：

 void Oscillator::updateIncrement() { double pitchModAsFrequency = pow(2.0, fabs(mPitchMod) * 14.0) - 1; if (mPitchMod < 0) { pitchModAsFrequency = -pitchModAsFrequency; }

ここで何が起こっていますか？ mPitchModeは-1から1まで変化しますが、491.3 Hzの表現をプラスする方が便利です。 powはヘルツへの変換に役立ちますが、 fabs呼び出すと負の値が失われfabs （絶対値）。次のifは負の値を返します。最後に1を引く必要がありますmPitchModがゼロのとき、式pow(2.0, 0) mPitchMod pow(2.0, 0)は1を与え、1 Hzのトーン変調を得るためです。これは間違っています。
次に、基本周波数mFrequencyと取得したヘルツ単位の値からCalculatedFrequencyを計算しcalculatedFrequency 。

  double calculatedFrequency = fmin(fmax(mFrequency + pitchModAsFrequency, 0), mSampleRate/2.0);

まず、これらの2つの周波数を追加します。 fminは、サンプリングレートの半分を超えないようにします。ナイキスト周波数を超えてはなりません。そうしないと、エイリアシングが発生します。 fmaxは、周波数がゼロを下回らないようにします。
さて、位相増分を追加します。

  mPhaseIncrement = calculatedFrequency * 2 * mPI / mSampleRate; }

もちろん、今はcalculatedFrequencyを使用しているcalculatedFrequencyを除いて、すべてが以前と同じです。

インターフェイスハンドル

パズルの最後のピース！その後、シンセの準備が整います！

LFOノブから始めましょう。それらは音声に影響を与えないので、それらに関してはすべてが他のパラメーターと多少異なります。 OnParamChange関数OnParamChange新しい関数に置き換えます。

 void SpaceBass::OnParamChange(int paramIdx) { IMutexLock lock(this); IParam* param = GetParam(paramIdx); if(paramIdx == mLFOWaveform) { voiceManager.setLFOMode(static_cast<Oscillator::OscillatorMode>(param->Int())); } else if(paramIdx == mLFOFrequency) { voiceManager.setLFOFrequency(param->Value()); } }

どのパラメーターが変化しているかを確認し、 setLFOModeまたはsetLFOFrequencyを呼び出します。これらの2つの関数はまだ作成されていません。VoiceManager.hの publicセクションで実行してみましょう。

 inline void setLFOMode(Oscillator::OscillatorMode mode) { mLFO.setMode(mode); }; inline void setLFOFrequency(double frequency) { mLFO.setFrequency(frequency); };

ご覧のとおり、どちらもmLFOセッターを呼び出すだけです。

他のパラメーターには、C ++の機能メカニズムを使用します。これらは非常に強力で便利なものですが、言語ガイドではあまり話されていません。それらについて知る価値があることに同意すると思います。では、これはどのような問題ですか？

ノブを回すと、パラメーターIDとその値でOnParamChangeがOnParamChangeれます。 0.3値でmFilterCutoffと言います。次にVoiceManager次のVoiceManager 。 「各Voiceに0.3フィルタースライスを設定します 。」さらに、おそらく、次のようなsetFilterCutoffForEachVoice関数を呼び出します（デモのためだけに示します）。

 VoiceManager::setFilterCutoffForEachVoice(double newCutoff) { for (int i = 0; i < NumberOfVoices; i++) { voice[i].mFilter.setCutoff(newCutoff); } }

すべてがうまくいくように思えますが、異なるパラメーターに対して約10個のそのような関数が必要になります。それぞれがわずかに異なりますがforすべて同じです。「これは変更です。 すべての投票に適用する必要があります 。」と言うことができればうれしいです。 C ++では、そのような機会は自然に存在します。関数を取得し、最初にいくつかの入力値を入力し、それを呼び出してさまざまなものを処理できます。これはJavaScriptのFunction.prototype.bindに似ていますが、データ型の互換性チェックのみがあります。
このアプローチを試してみましょう！ VoiceManager.hに追加します。

 #include <tr1/functional> // #include <functional> if that doesn't work

public追加：

 typedef std::tr1::function<void (Voice&)> VoiceChangerFunction;

VoiceChangerFunctionは、 Voice&を最初のパラメーターとして取り、 voidを返す関数です。実際、これが関数である必要はまったくありません。 ()で呼び出すことができるものはすべて() 。
その後、関数を追加します。

 inline void changeAllVoices(VoiceChangerFunction changer) { for (int i = 0; i < NumberOfVoices; i++) { changer(voices[i]); } }

VoiceChangerFunction 、すべてのボイスをVoiceChangerFunctionし、すべてのボイスに適用します。
この下に、関数自体を追加します。それらはすべてほぼ同じように見えます。それぞれが音声と音声およびその他のパラメーターへのリンクを取り、その音声を変更します。

 // Functions to change a single voice: static void setVolumeEnvelopeStageValue(Voice& voice, EnvelopeGenerator::EnvelopeStage stage, double value) { voice.mVolumeEnvelope.setStageValue(stage, value); } static void setFilterEnvelopeStageValue(Voice& voice, EnvelopeGenerator::EnvelopeStage stage, double value) { voice.mFilterEnvelope.setStageValue(stage, value); } static void setOscillatorMode(Voice& voice, int oscillatorNumber, Oscillator::OscillatorMode mode) { switch (oscillatorNumber) { case 1: voice.mOscillatorOne.setMode(mode); break; case 2: voice.mOscillatorTwo.setMode(mode); break; } } static void setOscillatorPitchMod(Voice& voice, int oscillatorNumber, double amount) { switch (oscillatorNumber) { case 1: voice.setOscillatorOnePitchAmount(amount); break; case 2: voice.setOscillatorTwoPitchAmount(amount); break; } } static void setOscillatorMix(Voice& voice, double value) { voice.setOscillatorMix(value); } static void setFilterCutoff(Voice& voice, double cutoff) { voice.mFilter.setCutoff(cutoff); } static void setFilterResonance(Voice& voice, double resonance) { voice.mFilter.setResonance(resonance); } static void setFilterMode(Voice& voice, Filter::FilterMode mode) { voice.mFilter.setFilterMode(mode); } static void setFilterEnvAmount(Voice& voice, double amount) { voice.setFilterEnvelopeAmount(amount); } static void setFilterLFOAmount(Voice& voice, double amount) { voice.setFilterLFOAmount(amount); }

ただし、それらをchangeAllVoices関数に渡すことはできません。誰もが複数の引数を取るため、 VoiceChangerFunction関数ではありません。最初の（ Voice& ）を除くすべての引数を事前に入力します。そして、これはそれらをVoiceChangerFunction関数にVoiceChangerFunctionます。
