Patch map

The following image shows the 1000 patches of the Matrix-1000, each represented by a small colored square. There are 50 squares per row, so each bank is two rows.

Red squares are patches that either use filter modulation or have a click. These are likely the last features that I will try to simulate.

White square patches have a noise component in them. Most of them are in the “FX & Perc” bank.

Yellow patches use only square wave DCOs, blue patches use only the variable waveform, and green patches use both square and waveform DCOs.

This patch map suggests that it should be possible to simulate most patches even before implementing filter modulation, and that I may be able to simulate up to one fourth of the patches (there are 250 yellow squares) after implementing the square wave, the filter and digital control (including envelopes, LFOs and matrix modulation).

It’s also interesting to note that there are two black squares. These correspond to patches with no oscillators and no noise. How is it possible for these patches to produce sound then? The two patches are called heart and zap and loading them in an editor shows that their filter resonance is set to the maximum possible value, so these patches are using the ability of the filter to self-oscillate and produce a sinusoidal output even when it has no input signal.
