WMD Metron is a 16 track Trigger and Gate sequencer with tons of deep features, real-time control, and a very easy to use interface.
METRON can be expanded to have up to 64 CV tracks as well by adding the Voltera expander (4 CV tracks per Voltera)
Metron also sends commands via S.BUS to communicate to other modules that are on the same powered bus board. These messages are MIDI program changes that are primarily used for recalling presets on other modules using the METRON interface.
In this video, Alex goes through how to set up your METRON to send these program changes to the Malleko Voltage Block, allowing you to change the Voltage Block's presets remotely and automatically from METRON. this is great for a Eurorack live performance, where you are using METRON as the master sequencer, but would like to recall presets on your voltage block. METRON's S.BUS function allows you to send multiple messages in one sequence, per variation, or per track. Eseentially treated as a 17th track, you can also change the pattern length of the S.BUS track independent of the other tracks, meaning you can have a polymetric feel to your program changes.
