The MBSEQ_HW.V4 File
Forum Discussion Thread - for comments, corrections, or questions about this article
This file contains configuration information about your SEQ's hardware - button, LED, and encoder assignments, some low level settings, etc. This file has to be in the root of your SD Card in order for the Wilba Frontpanel to work, because without this file, the SEQ core won't know anything about the buttons and LEDS on your frontpanel.
The MBSEQ_HW.V4 file is actually pretty well self-documented. If you want to understand it, read through the example MBSEQ_HW.V4 files available in this directory in the MIOS Subversion Repository.
Buttons, encoders, and LEDs are assigned in this file by specifying the Shift Register (the 74HC165 IC chips on your PCB) and Pin to which they are attached.
Config File for the Wilba Frontpanel
If you've just built a MIDIbox and all you want is for your Wilba Frontpanel to work, then you really don't need to understand this file. Here is a standard MBSEQ_HW.V4 file for the Wilba Frontpanel. Just make sure that file exists in your SD Card root.
Example MBSEQ_HW.V4 files
- For the standard SEQ V4 - This is not the Wilba Frontpanel - it's the “traditional” frontpanel referred to on this page.
Adding Modules to Your SEQ
Some modules, like the TPD (Track Position Display) module, the AOUT_NG module (provides CV outs), and hardware Button LED Matrices (BLMs) require amendments to the MBSEQ_HW.V4 file. To learn a bit about how this works, see, for example, the configuration documentation on this page about the TPD module.
