Orthogonal Devices ER-101 ER-102 Review (Part 1) Euroroack Modular Indexed Quad Sequencer & Controller - Clickable Index (2018)
Click on SHOW MORE to see INDEX of the video and more info in the description.

The Orthogonal Devices (OD) ER-101 is a Eurorack Modular Four Tracks Gate and CV Sequencer with 1 Gate and 2 CV channels per Track.

The ER-102 is the Sequencer Controller expander module which augments overall sequencing and modulation capabilities and also adds CV/Gate Recording.

In Part 1 of this ER101 and ER102 Review video series,
(Subscribe to this YouTube Channel, do not miss next episode!), we take a look at the overall features of both modules and we focus more on the main features of the ER-101, from a high-level understanding of this unique Sequencer to hands-on examples including Step Editing, Math Transforms, Smooth, etc...

Does the Orthogonal Devices ER-101 Sequencer and User Interface Paradigm work?

In Part 2 we will focus hands-on on the Orthogonal Devices ER-102 Sequencer Controller module
