The WAV Trigger Pro improves on the previous versions with a more powerful processor, enhanced MIDI processing - including velocity switching and multi-timbral support - and MIDI USB Device **and** MIDI USB Host support (see note), all in a smaller 1.75in. x 1.5in. footprint! It supports up to 4096 uncompressed 16-bit, 44.1kHz mono, and stereo WAV files matching CD audio quality. The WAV Trigger Pro supports polyphony and can play and mix up to 24 tracks simultaneously and independently with exceptionally low latency (2-3ms typically). Control track playback via eight programmable trigger inputs, I2C (Qwiic), or MIDI (USB or Serial UART). The board can function as both a USB MIDI device *and* host, meaning if the WAV Trigger Pro has power in USB MIDI Host mode, it can supply up to 500mA@5V to a connected MIDI device over USB-C, allowing for USB MIDI control with no computer required! Audio output is over two unbalanced channels (Left & Right). These audio outputs are only routed to a 0.1"-spaced plated through-hole (PTH) connector, so some *soldering is required*. The WAV Trigger Pro also includes a new feature: **Presets**! Presets are spreadsheet (.csv) files that describe up to 8 actions per MIDI note based on channel and velocity. These actions can toggle an independent track with specific gain, balance, attack, release, and pitch. This allows multiple sounds to be mixed during the performance. Assigning action velocity ranges allows for velocity switching per note. Create preset files using a spreadsheet program (Excel or Google Sheets™), then load them onto the microSD card. **Note:** Using the WAV Trigger Pro as a MIDI USB Host requires uploading alternate firmware and adjusting the solder jumpers.
