Plan the Patch Architecture

Now we turn the block diagram into an empty Poly Grid patch. The patch will not make music yet. Its purpose is to give every later module a sensible place.

The Idea #

Grid does not have reusable subpatches or a separate interface editor. Layout therefore carries part of the documentation. Labels, spacing, signal direction, and test points help you understand the patch after it has grown.

We will use a left-to-right flow:

TIMING | PITCH | MEMORY AND FORM | SOUND LAYERS | MIX AND FX | OUTPUT

Control and trigger signals move toward the sound layers. Audio then continues toward the output.

Build It Step by Step #

1. Add an empty Poly Grid to an instrument track.
2. Click an empty area of the Grid to open the device settings in the Inspector.
3. Set the device to True Mono so one voice remains active without incoming notes. Do not use Digi Mono for this self-running patch.
4. Turn voice stacking off for now.
5. Set the device phase length to one bar and let it follow the project transport.
6. Place an Audio Out at the far right.
7. Add a final Gain - dB before Audio Out and start with it turned down.
8. Add large Label modules from left to right: TIMING, PITCH, MEMORY + FORM, SOUND LAYERS, MIX + FX, and OUTPUT.
9. Leave generous empty space below every label. The sound-layer and mix areas will need more room than the timing area.
10. Place an Oscilloscope in the timing area and a Value Readout in the pitch area. Leave them disconnected until needed.

If you use colors, choose a simple rule and keep it for the complete course. For example:

• yellow for triggers and timing;
• blue for pitch and other control signals;
• one color per sound layer;
• green for audio mixing and effects.

The exact colors do not matter. Consistency does.

Add Safe Test Points #

Place a Gain - dB or another clear level control at the future output of every sound layer. Do not wait until the final mixer to control loudness.

Add a Peak Limiter in the Poly Grid Post FX chain while experimenting. It is protection against mistakes, especially when feedback or several layers are added. It is not a replacement for keeping the internal levels sensible.

Save the preset as:

Grid System 00 - Skeleton

Checkpoint #

Your patch should now have:

• True Mono operation;
• a one-bar device phase;
• labeled areas with visible space between them;
• Audio Out with a lowered final level;
• an oscilloscope and pitch readout ready for testing;
• no oscillator, random source, or effect inside the patch yet.

Zoom out. You should be able to understand the intended signal direction without reading any cables.

Common Problems #

The patch stops when no note is held #

Confirm that the device is in True Mono. Digi Mono and polyphonic modes still depend on incoming notes.

The layout already feels crowded #

Move the labels farther apart. Empty space is useful during construction. Compact the patch only after the blocks work.

Long cables will have to cross everything #

Do not solve this yet. First keep shared sources near the left and destinations near the right. Later you can use named Modulator Out connections for a small number of truly global signals.

Extend the Patch #

Add a small Comment module below every label and write what the block should receive and produce. For example, Receives device phase / Produces note and detail triggers. These comments are especially useful when you return to the preset months later.

In the next lesson we fill the first area with one timing backbone for the complete patch.
