The next big “Learning Modular Synthesis” project is Eurorack Expansion. The idea behind it is that you already have a semi-modular synth or a small modular system, and now you’re wondering what to add next. As the saying goes, you need to walk before you can run. I’ve built up a core set of deceptively boring yet essential modules that will make it easier to interface your core system with the fun new modules you’re dying to try out.
Modern MIDI controller keyboards come with a lot of input options. However, very few MIDI to control voltage + gate (CV/Gate) converters have enough outputs to take advantage of all these performance inputs, plus restrict how you use them to select operating modes. By contrast, the FH-1 comes with eight outputs (expandable to 64), with all of its operating modes available simultaneously. I’ll explain a couple of approaches to harnessing all that power.
Different oscillators and MIDI to CV converters may have varying ideas of what voltage a given note produces, and what pitch should you hear as a result. If there is a difference, in most cases it can be dialed out with a pitch knob or transpose switch. However, there are occasions when you need the assistance of an additional module to settle these disagreements.
