Beetlecrab Audio Tempera granular sampling instrument

Small scratches in the powder coating on the bottom near the micro SD card slot and near the 12V DC input, and even smaller ones on the bottom as pictured.

Updated to the latest firmware (v2.3) today and works perfectly.

Information from the website:
"Tempera is an electronic musical instrument, a hardware granular synthesizer which allows for a full hands-on approach to sound design and live performance. Blend tones like paint on canvas with pristine audio processing in a compact, sturdy build.

Grain skip probability

A probability setting determines how often grains are randomly omitted. This introduces sparse, stuttering textures with controllable density

Envelope follower modulator

Internal or external audio can be turned into a modulation source, converting dynamics into control signals.

Cross-modulation

Speed, size, and phase of any modulator are now routable as modulation targets

Per-emitter grain pitch

Grain detune for adjustment or as a modulation target.

Cell marker nudging

Live recordings don't always land neatly on the grid. Cell markers can be nudged for precise alignment with transients or natural phrasing.

Quad-macro control

A single macro knob controls four parameters at once. Macro states can be stored and recalled for instant macro changes.

Waveform zoom fit

The selected waveform can be stretched across all four displays, magnifying transients and overall shape for a better glance.

Grain shape tilt

The grain amplitude envelope can be tilted, creating an asymmetric shape towards asymmetric articulations, between plucked to reversed-swell.

Spec'd to the brim

• Global stereo pool of 4096 grains can be spread across 16 voices of polyphony, or all channeled into a single voice
• Per-voice ADSR amplitude envelope
• Per-voice multi-mode filter, including 12 dB/oct resonant low-pass, band-pass, high-pass, 24 dB/oct resonant low-pass ladder, rake and a formant filter
• Ten per-voice modulators, including attack-decay and attack-release envelopes, smooth and S&H noise functions, multiple LFO shapes, aftertouch and mod wheel, with many modulator destinations, allowing multiple sources to be routed to a single destination
• Per-emitter 6 dB/oct tone-shaping with variable-width band-pass filter
• Up to 64 placed emitters per voice, each configured to trigger sporadically or as an avalanche of grains
• Four concurrent emitter configurations with optional Euclidean sequencing, played all at once or on different MIDI channels for multi-timbrality
• Integrated FX chain with high-fidelity Chorus, Delay, Reverb and Patina, all processing at once
• 8GB internal storage fits more than 200 canvases (8 samples each), extendable by a plugged in micro SD card
• Built-in onboard microphone to sample audio without external equipment
• Record and resample Tempera's audio output internally
• Live grains processing for real-time granularization of the audio input
• Onboard overlay PolyAT keyboard with multiple layouts for standalone operation
• Each of the 8 loaded stereo samples can be up to 11 seconds long
• Dimensions 20.0×14.6×3.4 cm (5.4 cm including knobs)"
