Mandala Mk2
Download the firmware binary file from the link below, and unzip it.
The firmware must be uploaded to the Mandala with the Teensy Loader software.
Plug a micro USB cable between your computer and the Teensy board on the back of the module.
Start the Teensy Loader program, go to File > Open HEX file, and select the firmware file on your computer.
Press the white button on the Teensy board. The upload will start, and after a few seconds the module will restart.
Done!
Global note: your saved presets have a good chance to be lost, as the file format may evolve (for the better!)
1.0.9
- Fixed: Track synchronization issue when playing with the track lengths.
- Fixed: Track copy: issue if the source track was rotated
- Added: Customizable CV range (shuffle)
- Fixed: Clock input was triggered on falling edge.
- Fixed: Display the right BPM in slave mode. Calculated from the clock source, can show a few inaccuracies.
1.0.11b
- Improved readability of the menus. Big rewrite of the menu system.
1.0.11c
- Fixed: Melodic shuffle (CV controlled) was using the currently displayed track as CV reference.
- Added: clock input divider, clock output divider
- Live mode : press the track button to send a trigger, quantized against the clock.
- Microstepping is back
- Link tracks: a track can reference another track and its steps stay in sync (excepted if they are locked)
1.0.13
- Fixed bug in the external clock + reset signal handling.
- MIDI input clock handles up to 400bpm. MIDI output clock is still relatively unstable.
- In slave mode, microsteps were not working
- Adjusted the current step display to get something more relevant in terms of position on the circle.
- Loading an empty quicksave now requires a long press: is prevents accidents !
- Linked tracks : the slave tracks are now shown with the same color as the ref. track.
- Pressing SYS now hides the menu if it was already displayed (i.e. toggle mode).
- Transposition modulation now works
- Linked tracks are displayed with the same color as the reference track.
- Click on an empty quicksave now does nothing. A long press is required to actually load the empty quick save. It prevents accidental clearing!
1.0.14
- Fixed live mode menu item: now reflecting the real state.
- Finally added the per-track clock division!
1.0.15
- When muted while playing a trig: the trig output stays high (rare event)
- The screen automatically turns off after 5 minutes.
- Fixed: When displaying a track that is quantized, the tempo slows down
- Master mode: displaying cv mappings was also slowing down the real bpm
- Quick saves now also store the track's envelope information, clock divider and track links
- Check preset file compatibility to avoid byd surprises when loading if the file structure changed between firmware versions.
- Display the active substeps on the screen when we are in substep edition mode
- Live mode: also triggers envelopes!
- Fix clock div in glide mode
1.0.16
- Added root note in the track menu. Used to display the correct notes on screen, according to the VCO tuning.
- When live mode is enabled, the track copy feature is now disabled. It prevents unwanted copy when we just want to triiiiiigger steps manually.
- New on-screen display for transposed tracks
- Really fixed now : when muted while playing a trig: the trig output stays high (not so rare event! )
- Fixed a bug in the input clock divider. Counting was really bad.
- Fixed: in slave mode: live mode was crashing the sequencer, due to SPI reading in an interrupt context.
1.0.17
- The shuffle range was only taken in account when shift+clicking Sh. It works now with simple clicking on Sh.
