Before I go to bed, I would like to ask for volunteers to bang on this pre-release candidate. Specifically I want you to bang on the new CUSTOM UNIT which lets you build your own units using other existing units and tell me your thoughts. Download links at the bottom.
CUSTOM UNIT QUICKSTART
- Insert a CUSTOM UNIT
- Focus press the unit’s header to get the unit’s menu.
- Select Edit Controls.
- Press and hold “change” (S1) while turning the encoder to set the active control type.
- Press “Add Control” (S2) to add a control of the active type to the unit.
- Press UP when you are done.
- Build the internal chain: Press the CUSTOM UNIT’s “open” button to view the unit’s internal chain. Build something here. The input of this internal chain is the input of the custom unit. The output of this internal chain is the output of the custom unit.
- Use the custom unit’s controls to control parameters anywhere inside the custom unit’s internal chain: Whenever you assign an input to a branch of a unit in this internal chain, notice that you have “Local Sources” that you can select (in addition to the usual “External Sources”). These local sources are the controls that you added to the custom unit.
Some of the major things that I would like you to ignore for now:
- 6-track recorder is disabled (under reconstruction)
- Lack of UI for renaming for parameters of custom units.
- Lack of UI for reordering of parameters of custom units.
- Lack of promised new units. They are coming!

There is a possibility that quicksaves and presets made with this new version are not backwards compatible. So to be safe you should make a copy of your ER-301/sc directory before switching firmware.
er-301-v0.1.6p15-48kHz.zip (1.3 MB)
er-301-v0.1.6p15-96kHz.zip (1.3 MB)
Note: If you installed the unpatched version of this firmware, then you will find that the Firmware Update screen has a bug that prevents you from installing another firmware via the FRONT sD card. This bug gets fixed in patch 2 but in order to install it you will need to so via the Emergency Manual Update Procedure (E.M.U.P.):
The Emergency Manual Update Procedure
(This is not the normal firmware update procedure! You only need to do this if the regular updater using the FRONT card fails for some reason.)
- Download the firmware archive that you want to install and unzip its contents on your PC.
- Unscrew your ER-301 from the case and look at the back. There is a SD card on the back. I will call this the REAR SD card. Take out the REAR SD card and bring it to your PC.
- Using your PC, copy the 3 files that were in the firmware archive (MLO, SBL, kernel.bin) to the root directory of the REAR SD card of the ER-301. You will overwrite the 3 files on the card already and that is OK.
- Put the REAR SD card back in the ER-301 and power up. You are done.
