In this tutorial, we're going to make a simple drum rack consisting of a kick drum, snare, and hi-hat.

External Connections

You will need to make four cable connections to get started. Three of them will be gate or trigger signals for each of the three drums, which you will generate using another module. For this tutorial we will use channel 1:

  1. Patch OUT1 to your mixer or sound card.
  2. Patch your incoming kick drum gate/trigger to A1
  3. Patch your incoming snare drum gate/trigger to B1
  4. Patch your incoming hi-hat gate/trigger to C1

For more information about which inputs are appropriate for various signal types, see Front Panel Inputs.


You can use any kick, snare, and hi-hat samples that you like. The following zip file contains one sample of each. If you'd like to use these, then unzip these to your SD card. Place them in the ER-301/samples directory. If the samples directory doesn't exist, you can create it.

Saving Your Work

A drum rack is pretty handy to have around for quick recall. So let's save our work. We're going to do 3 different kinds of saves here. Refer to Persistence for full details about the various save options. Here's a quick overview of the three saves we'll be performing:

  • Quicksave: this saves the entire state of the ER-301 including all four channels, and any global chains (not used in this tutorial) for recall. These are great for recalling when you power up, or if you want to completely switch gears on what you're doing.
  • Channel Chain Save: this will save everything on Channel 1, so we can restore this drum rack without affecting anything on the other channels
  • Mixer Channel Save: we'll save one individual mixer as a preset. This will make it easy to add a new drum to the rack.
