1. New options added. They are on the “options.txt” file which is found on the root directory of any microSD card that has been mounted in a Morphagene. See the MG155 changelog on page 34 of the manual for more information on this file.
The new options mcr1, mcr2, and mcr3 allow user-definable Morph Chord Ratios (detuning of 2nd through 4th Genes with Morph at its highest settings). Historical settings have been 2.00000 (+1 octave), 3.00000 (+1 octave & 5th), and 4.0000 (+2 octaves). Now you can set any ratio from 0.06250 (-4 octaves) to 16.00000 (+4 octaves). Ratios are accurate to five decimals. You can also make one or more individual Genes play in reverse with this setting by using negative numbers. A value of 1.00000 results in unison (no detuning). A list of 12-TET ratios is provided as comments in the text file for easy copy/paste.
2. The Auto-level procedure has been replaced with an improved input gain staging, accessed with a 4-step gain selection (blue-green-orange- purple). To use, Hold Record, and Press Shift to step through the gain settings: Blue: low -3db, Green: modular level, Orange: medium +6db, Purple: high +12db.
3. Playback gain is reverted to pre-mg157 level to improve TLA and Record-Into-New-Splice functions.
4. Internal processing improved to work with (2) and (3) to significantly improve signal-to-noise ratio on input and playback.
5. Minor bug fixes.

We check Make Noise's official download page for the Make Noise Morphagene every day. One message per release. No spam, no newsletter.
Download the firmware zip and unzip it. Remove the microSD card from the Morphagene. Patch the output of a phone or computer into the Morphagene Left Signal IN, set the playback volume to 80% and silence every other sound (airplane mode on a phone). Power on the system while holding the REC button; when only the SPLICE window is green, release REC. Play the WAV file: the windows flash while the data arrives and all lights flash when it is done. Turn the system off, then power on while holding SPLICE, release it, turn Vari-Speed fully counter-clockwise and fully clockwise, press SPLICE and power-cycle once more. Check the Reel and Splice colours on power up, then put the card back. If it fails, retry with the volume at 60%.
