Hi friends - I’m pleased to share a new alternative firmware for Plaits. The changes are minor but add two quality of life features I’ve personally been wishing for. I hope some of you also find them useful.
First and foremost, this revision adds frequency locking for Plaits in the style of Frap Tools Brenso. To lock or unlock coarse frequency, you long-press (2+ seconds) both buttons at once. The FM attenuverter continues to work as a fine frequency control when the FM input is unpatched, and the V/Oct and FM inputs continue to work as normal when patched.
This gesture replaces the calibration procedure, so if the module needs to be recalibrated for any reason after installing this alt firmware, you’ll need to revert to the stock firmware first. This can also be seen as a benefit, as you’re less likely to end up accidentally recalibrating your module.
In addition to making it harder to inadvertently detune the oscillator, this frequency locking frees up the frequency knob for other purposes. When frequency is locked a hidden parameter is now exposed, controlled manually by the frequency knob, for crossfading between the main and aux synthesis models (full-CCW for the main model, full-CW for the aux model). This crossfaded output will be present at the aux output while the main output continues to output only the main synthesis model as in the stock firmware. This replaces the need for an external mixer/crossfader in order to use both models at once, though it is not under voltage control - for voltage controlled crossfading you’ll still need to use an external module or two.
If you’d like to use the aux crossfading without the frequency locking, you can simply switch into frequency locked mode, adjust the crossfade, and then switch back out; the aux crossfade setting you’ve chosen will be maintained.
Frequency locks and aux crossfade settings are preserved across power cycles.
Thanks to @joeSeggiola for sharing his script for generating and playing new firmware files, which helped speed up my development cycles.
