v25.2 RC1

Testing firmware for parameter takeover

v25.1

• New device supported - Daisy Pod
• Bootloader updated to use separate error state LED when available

v25.0

• Added support for Seed 1.1 on Bluemchen and Daisy Patch
• Daisy Patch can switch audio setup between quad channel mode or stereo for old patch builds. Stereo mode still can run patches that are configured to output 4 channels when building with PATCHIN/PATCHOUT parameters

v24.2.0

Support for PatchSM hardware and Patch.Init() module

Daisy Patch build that uses only external codec added, don't use it if you need 4 channel audio

v24.1.0

• fixed occasional hanging during patch loading
• PLUSRAM support
• support for SSD1306 displays and WM8731 codec (untested)

v24.0.0

• SD card support, finally! Please see SD usage info for explanation about reading files from SD card.
• SD card browser menu
• Option to reboot device added to system menu

Bootloader additions:

• Extra checks for making sure that hardware used for bootloader and firmware match
• Additional code for breaking reboot cycle in case of boot failure

v23.0.0

• KXMX Bluemchen 🌹 support added
• Changed multichannel audio mode to be based on number of patch inputs/outputs (use PATCHIN=4 PATCHOUT=4 when building patches to get quad audio on DaisyPatch)
• Daisy Patch UI fixes (because you can't deal with C strings without bugs, ever)
• ADC tweaks to get more stable sampling
• OwlProgram fork previously used for Owlsy is no longer needed or maintained - upstream patches work with H7 MCU and multi-channel audio

v22.1.0

• QSPI chip is still accessed by patches for reading LUTs, enabling cache for it improves performance in some patches
• Added pushbutton parameter ID support (takes its input from button 1, sets its output to button 3)
• Changed "Gates" menu to include pushbutton. It can be triggered by encoder click in that menu.
• Use hysteresis for parameter display, no more jumping values due to ADC noise
• Fixed DMA buffer location for serial MIDI TX buffer
• Merged various updates/fixes from upstream OWL firmware

Current parameter mappings happens to be the same as used by RebelTechnology Lich:

• input params - A, B, C, D
• output params - F, G (E is “expression pedal input” on original Owl module/pedal, so it shouldn’t be used as an output, Lich does the same thing)
• input buttons - 1 = pushbutton, 2
• output buttons - 3 = pushbutton

v22.0.0

This is a major update that allows loading binary compiled with upstream OwlProgram repo.

• Memory layout changed to be compatible with OWL - this breaks compatibility with old patch binaries, storage must be erased after updating via "System" > "Erase patches" menu
• Added backwards compatible mode for running stereo patches (detected automatically). This allows running patches from official Rebeltech library.
• Additional fast RAM sections used as dynamic memory, typically giving noticeable performance improvements
• Added resource storage access from upstream
• Added support for bootloader updates via MIDI
• FAUST patches will be built with faster memory buffer processing code, requires recent compiler version
• Experimental SOUL patches support
• New "System" menu for some firmware functions previously available from MIDI only

v21.1.0

Second Owlsy release has the following changes:

• Enabled USB audio channels - device is usable as quad channel USB audio interface capturing its inputs
• Raised MCU clock from 400 MHz to 480 MHz
• Reclocked SAI to run codec at exactly 48000 Hz
• Various updates to resource menu for upcoming flash resources support
