Building a Synth Using Macros

Adding an Oscillator and an ADSR Env to the Instrument

Do the same again, but this time connect the Instrument Out to the Input port of the Au­ dio Out Module labeled 2. This will place the sound on both Left and Right Outputs to your audio system. Your connection should look like this. The yellow lamp in the bottom right corner of the Instrument confirms the connection!

7.3Adding an Oscillator and an ADSR Env to the Instrument

Now we need to add an Oscillator Macro, an ADSR Env and make the connections. We al­ so need to insert NotePitch and Gate Modules, so that we can play our Synth via our MIDI keyboard.

7.3.1Inserting an Oscillator

1.First, make sure you are inside the Instrument. To go inside the Instrument, doubleclick the Instrument Object.

2.To insert an Oscillator Macro into the Instrument Structure, right-click if you are in Windows® ([Ctrl]+click if you are in Mac OS® X) on a blank part of the Instrument Structure and choose the Macro > Building Blocks > Oscillators > Osc (pls, saw, tri) menu entry. An Osc 3 Wave Oscillator will appear in the Instrument Structure and In­ strument Panel.

3.In the Instrument Structure connect the Out from the Osc 3 Wave Macro to the Audio Voice Combiner, by clicking and dragging so that the wire connects, much the same as we did before when we connected the Instrument to the Audio Output Terminals.

7.3.3Inserting Pitch and Gate Modules

Next we need to add a couple of components—Modules in REAKTOR terminology. The Note Pitch and Gate Modules will enable our MIDI keyboard to play this Synth.

1.Right-click if you are in Windows® ([Ctrl]+click if you are on Mac OS® X) on an emp­ ty space in the Instrument Structure and choose the Built-In Module > MIDI In > Note Pitch menu entry to insert the Note Pitch Module into the Structure.

2.Repeat the same procedure but choose the Built-In Module > MIDI In > Gate menu entry for the Gate Module.

7.3.4Connecting the Pitch and Gate Modules

Now we need to make connections so that we can play our fledgling Synth.

1.Using the same click and drag techniques as before, connect the NotePitch Module to the P (Pitch) Input of the Osc 3 Wave Macro.

2.Then connect the Gate Module to the G (Gate) Input of the ADSR-Env Macro.
