Beetlecrab Audio Tempera firmware

See the archived v2.2 manual. - Reverse grains parameter sets the percentage chance of an emitter emitting a grain in reverse. - On-grid PolyAT sensing. It acts as a per-voice modulator and can be targeted to any of the parameters. - Patina effects: Age, Slip and Compress to dirty up Tempera's output - Step LFO modulator, an up to 16-step per-voice modulator source. - Euclidean grain sequencing per emitter, up to 16 steps - Reverb model much improved on the previous, handles well transient sounds. - Batch loading of samples from a folder to populate some or all tracks at once - Storing project BPM per canvas - Emitter copy-pasting to quickly move emitter configuration to another, even between canvases. - Handy save overwrite the currently loaded canvas in the system info screen. - External MIDI PolyAT works simultaneously with onboard PolyAt. - Canvas merging function to load a canvas while keeping the current audio files. - Trigger a track recording via MIDI on the "MIDI control" channel. First track by note 100 (E7), second by note 101 (F7) and so on. - Hand-tuned MIDI CC curve for grain cell length and density to better map the 127 CC values. - Recording auto-trim option which automatically trims a sample to fit after a Replace recording. - Synced LFO retrigger option to restart a synced LFO on note on, while keeping it tempo-synced. - Crash reporting mechanism: when Tempera crashes, it displays useful info on how it crashed, please send a photo when this happens. - Pitch detector is now both faster and more successful. - Emitter volume allows live tweaking and modulating an emitter's volume. - Improved emitter menu navigation by turning the knob LEDs to an emitter's color - Improved rake filter by adding negative emphasis - Placing emitters with MIDI notes on a dedicated "MIDI control" channel - Improved ADSR which now changes audibly when tweaked on a playing note - Track auto-name when recording into an empty track [...]

See the archived v2.1 manual. - Tempera is now also a live grain FX processor: a track can be continuously recorded into while emitters are placed on it. Rather than the playhead moving across the track, the track itself is scrolling under the finger. - New Rake filter: a custom designed comb filter configuration with an optionally amplitude-modulated feedback path. The rate of the modulation is the same as the comb feedback frequency and both can be key-tracked. - New modulator destinations, sources and visualizations: Note velocity, Note tracking and Grain pan are new routing options, plus each modulator now draws a plotter-scope of its activity. - New filter visualizations in the UI to have a better overview and understanding of what the filter is doing and how it’s being modulated. - New "Align X=off" option where a grain can be emitted in between tracks. When that happens, the grain will play a weighted sum of the neighboring tracks, in other words when smoothly moving across the tracks they will be cross-faded. - New Filter send option to toggle each emitter to go to the main per-voice filter or not, useful to achieve better separation between emitters configured for different purposes. - Reworked and improved Reverb and Delay. The reverb is much smoother and more lush, and the delay’s band pass filter is more pronounced. - New Attack option for grain emission which makes the first emitted grain sharper, which gives a solution to playing long smooth grains with sharp attack at the same time. - Tap tempo and internal clock control, useful when by-ear tempo decisions are more convenient or when Tempera acts as a clock source. - MIDI clock improvements and built-in tempo corrections so Tempera stays in sync with various clock sources. - MIDI Program Change support to quickly load canvases from external MIDI devices. - New exotic and pentatonic scales for the Overlay Keyboard including modes, pentatonics and a few specialty scales.

See the archived v2.0 manual. - Per-emitter FX send level: Adjust the amount of effects applied to each emitter for eg. better separation of percussive and tonal sounds. Layering complex sounds has become much easier. - Double the amount of modulators: From 5 per voice to 10 per voice. - Relative X and Y scrubbing: Easily grain-scrub in two dimensions across the touch grid surface. Perfect pairing for the Tempera concept. - Adjustable LED and emitter colors: Personalize the look of your Tempera, including having better color separation for those of us with a different color perception. - Improved onboard keyboard: The new chromatic piano-like keyboard layout has better usability and clear visual feedback for standalone operation. - Quantized random grain detune: Grains’ random detune can now be quantized to fifths, octaves, or both, providing a natural shimmer or extra harmony. - Reverb upgrade: The new reverb algorithm provides richer and smoother reflections, and faster diffuse properties. Perfect for lush and wide soundscapes. - Modulator visualization: Modulators now provide improved visual feedback so it’s easier to get a clear picture of their behavior. - Stable and reliable MIDI clock sync: Improved clock BPM detection, MIDI clock sync is now durable and reliable. - Canvas quicksave: Save your project (“canvas” in Tempera lore) immediately with a quick and handy shortcut. - New shortcut for emitter editing: Newly added shortcut makes it easier to edit, cycle and organize emitter configurations. - New global MIDI channel parameter: Integrate Tempera easily into a bigger setup, while allowing for per-emitter MIDI channels. - Delay upgrade: A dot mode is added, along with smoother filter coloring. - Micro SD card USB bridge: It is now possible to bridge the micro SD card contents over USB to a computer. - Bug fixes & polishing: The amount of bugs fixed, streamlining and polishing is too long to list. :-)

See the archived v1.5 manual. - New per-emitter Tone filters: consists of a stereo pair of 1-pole LP and HP filters and it has two parameters: Width and Center. It can work as a sweepable “DJ style” filter, or a smooth bandpass to give each emitter a place in the mix. - New modulator destinations: per-emmiter Volume, Grain size, Grain Density, and Tone. - Picking an audio slice from a long audio file: It is now possible to load a long audio file into Tempera (up to 5 minutes) and pick an up to 11s window from it to load into a Track. - Random Name Generator to save time when saving canvases (no more AAAA.canvas!) - Many new new global settings, like Velocity curve, Max volume, Audition volume, new recording mode Mix which blends half of old with half of new, adjustable Display brightness. - Small things, like Round button + keyboard to show/hide the overlay keyboard, and a new Chromatic scale option. - New Horizontal overlay keyboard variant. - The MIDI parameter table has been updated. - A lot of polishing and of course many bug fixes

- Added Emitter lock parameter that prevents a placed emitter from being overwritten - Added record overdub/replace modes - LED brightness adjustment - A bunch of bug fixes (midi clock, midi channels, emitter latch mode, USB midi, …)
