MAKING SENSE OF THE MODULATION MATRIX

The Pro-1’s modulation matrix is where much of the heavy lifting gets done. Sources range from the Filter envelope, the LFO, and Osc B; each can be routed to five destinations (both oscillators’ pulse widths and frequencies, as well as the cutoff of the filter). Impressively, you can route the sources to each destination either directly or via the Mod wheel, giving a lot of room to modulate your sound. The Pro-1 can also be used with external LFOs and envelopes in your Eurorack case for a very flexible synth voice.
