Great Scott! This ER-101 with ER-102 Expander by Orthogonal Devices may look like the control panel in Doc Brown's DeLorean time machine from Back to the Future—still, it can control and manipulate time in your modular rig and a wide array of other features that separates this sequencer from the rest.
With its real-time composition capabilities, you can create hundreds of steps in a sequence with variable duration, gate length, and scales. The ER-101 is a favorite among Eurorack enthusiasts because it allows them to create melodies and rhythms easily.
It can set both swing and gate lengths on a per-step basis, which makes it perfect for ratcheting and odd gate rhythms that are in time with the sequence. There's also built-in musical scales so you can quickly dial in melodic sequences in tune with whatever scale you choose. Another intriguing feature: the module can also produce smooth transitions that allow for a seamless flow from one pattern to the next. It's also ideal for creating full songs as well as live performances, as each track includes its own adjustable loop points.
Also included in this listing is the ER-102 expander, which extends the module's CV and gate outputs while increasing the number of modulation choices, enabling users to execute processes in groups of steps. The expander also has an SD card slot that may save numerous sequences and settings. When combined with the 101, the pair are a force to be reckoned with.
The seller is open to offers and has included the original silver faceplates. Check out the full listing now—it won't last long!
